Twenty-four feedlot Ile de France lambs (average weight of 15kg and average age of 60 days) were randomized to receive the different diets and slaughtered at 32kg body weight. Increases were observed in the concentrations of the saturated pentadecanoic, heptadecanoic and arachidic fatty acids; of the monounsaturated nervonic fatty acid and of the polyunsaturated α-linolenic, ɣ-linolenic and eicosapentaenoic fatty acids. Increased conjugated linoleic acid (CLA) was also found in the meat of lambs fed on 12.5% mulberry hay. In addition, the omega-3 composition was augmented, while the omega-3/omega-6 ratio was decreased in mulberry hay-fed animals. In conclusion, a more desirable fatty acid profile was observed in lamb meat following the substitution of mulberry hay in the concentrate of fed, resulting in improved nutritional characteristics of the meat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternative%20food" title="alternative food">alternative food</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=feedlot" title=" feedlot"> feedlot</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep%20meat" title=" sheep meat"> sheep meat</a> </p> <a href="https://publications.waset.org/abstracts/9723/fatty-acid-profile-of-meat-from-lambs-fed-on-diets-containing-mulberry-hay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">465</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5426</span> Comparison of Punicic Acid Amounts in Abdominal Fat Farm Feeding Hy-Line Chickens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozcan%20Baris%20Citil">Ozcan Baris Citil</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Akoz"> Mehmet Akoz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effects of fatty acid composition and punicic acid contents of abdominal fat of Hy-line hens were investigated by the gas chromatographic method.

The oil is mainly composed of unsaturated fatty acids (MUFA) where oleic acid dominate with 47,01 % of total fatty acids and PUFA's represented by linoleic acid (19,26 %). Concerning the biological survey, oil, at 10% and 20% doses of diet for 15 and 30 days of two periods of treatment, resulted in beneficial effects on the lipid profile of Wistar albinos rats previously fed with animal and vegetable fats. We observed decreases in total cholesterol, triglycerides (TGA), total lipids and LDL-C, and an increase in HDL-C "good cholesterol" probably related to the presence of a large amount of (MUFA) and (PUFA). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pistacia%20lentiscus" title="Pistacia lentiscus">Pistacia lentiscus</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil"> oil</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20profile" title=" lipid profile"> lipid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=monounsaturated%20fatty%20acids" title=" monounsaturated fatty acids"> monounsaturated fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=polyunsaturated%20fatty%20acids" title=" polyunsaturated fatty acids"> polyunsaturated fatty acids</a> </p> <a href="https://publications.waset.org/abstracts/14884/physicochemical-and-biochemical-characterization-of-an-oil-of-pistacia-lentiscus-fruits-and-its-effects-on-blood-lipid-profile-10364-ejsr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">361</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5423</span> Human Health and Omega 3 Fatty Acids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinpa%20Palmo">Jinpa Palmo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many research, omega 3 fatty acid which is a polyunsaturated fatty acids is proved to be very important and essential nutrients having many different health benefits but apart from other fatty acids, it cannot be synthesise by our human body. Therefore, we have to get these fatty acids by consuming diets and supplements rich in it. Even though human beings can live by consuming other important nutrients but can live much healthier and longer by consuming omega 3 fatty acids. American heart association AHA recommends for daily intake of omega 3 fatty acids specially by those people with coronary heart disease. Fish considering as nutritional valuable animal is mostly due to its lipid content (fish oil) in which these omega 3 fatty acids are present very significantly. Fish does not actually produce these omega 3 fatty acid in their body, but receive these fatty acids through the food web in which phytoplankton are the chief source of these omega fatty acids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title="fatty acid">fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=disease" title=" disease"> disease</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a> </p> <a href="https://publications.waset.org/abstracts/157895/human-health-and-omega-3-fatty-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5422</span> Physicochemical and Biochemical Characterization of Olea europea Var.

The physico chemical characteristics: acidity (0,73%), peroxide value (14, 16 meqO2/kg oil) and iodine value (74,08 g iodine/100 g of oil) are consistent with international standards. The dosage of FA revealed a wealth of oil with UFA (76,7%), mainly composed of 65.43% of MUFA whose major fatty acid is oleic acid (63,57%). The experiment on rats receiving a diet rich in saturated fats and hydrogenated oils revealed that the consumption of Oleaster oil at the dose of 10 g and 20 g for 15 and 30 days improves plasma lipid profile by decreasing the rates of TC, TG, TL, and LDL-C with an increase in the rate of HDL-C serum.

Garden snails (Helix aspersa) were picked up by hand from the Central Anatolia Region of Turkey, in autumn (November) in 2015. Fatty acid methyl esters (FAMEs) and cholesterol analysis were analyzed by gas chromatography (GC). The protein contents of snail muscle were determined with Kjeldahl distillation units. Statistical comparisons were made by using SPSS Software (version 16.0). Thirty different fatty acids of different saturation levels were detected. As the predominant fatty acids, stearic acid (C18:0), oleic acid (C18:1ω9), linoleic acid (C18:2ω6), palmitic acid (C16:0), arachidonic acid (C20:4ω6), eicosadienoic acid (C20:2) and linolenic acid (C18:3ω3) were found in Helix aspersa. Palmitic acid (C16:0) was identified as the major SFA in autumn. Linoleic acid (C18:2ω6), eicosadienoic acid (C20:2) and arachidonic acid (C20:4ω6) have the highest levels among the PUFAs. In the present study, ω3 were found 5.48% in autumn.

The present study analyzed the effects of dose-dependent gamma irradiation on the fatty acid profile of the muscle derived from the candidate species (S. serrata) at both qualitative and quantitative levels. Wild grown, average sized, intermolt male S. Serrata were gamma irradiated (^60C, 3.8kGy/ hour) at the dosage of 0.5kGy, 1.0kGy and 2.0kGy using gamma chamber. Total lipid extracted by Folch method, after methylation, were analyzed for the presence fatty acids adopting Gas Chromatograph equipped with flame ionization detector by comparing with the authentic FAME reference standards. The tissue from non-irradiated S. serrata showed the presence of 12 SFA, 6 MUFA, 8PUFA and 2 TF; PUFA includes medicinally important ω-3 FA such as C18:3, C20:5 and C22:6 and ω-6 FA such as γ- C18:3 and C20:2. Dose-dependent gamma irradiation reduced the number of detectable fatty acids (10, 8 and 8 SFA, 6, 6 and 5MUFA, 7, 7, and 6 PUFA and 1, 1, and 0 TF in 0.5kGy, 1.0kGy and 2kGy irradiated samples respectively). Major fatty acids detected in both irradiated and non-irradiated samples were as follows: SFA- C16:0, C18:0, C22:0 and C14:0; MUFA - C18:1 and C16:1and PUFA- C18:2, C20:5, C20:2 and C22:6. Irradiation doses ranging from 1-2kGy substantially reduced the ω-6 C18:3 and ω-3 C18:3. However, the omega fatty acids such as C20:5, C22:6 and C20:2 could survive even after 2kGy irradiation. Significantly, trans fat like C18:2T and C18:1T were completely disappeared upon 2kGy irradiation. From the overall observations made from the present study, it is suggested that irradiation dose up to 1kGy is optimum to maintain the fatty acid profile and eradicate the trans fat of the muscle derived from S. serrata. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20profile" title="fatty acid profile">fatty acid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20preservation" title=" food preservation"> food preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma%20irradiation" title=" gamma irradiation"> gamma irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=scylla%20serrata" title=" scylla serrata"> scylla serrata</a> </p> <a href="https://publications.waset.org/abstracts/22523/effect-of-dose-dependent-gamma-irradiation-on-the-fatty-acid-profile-of-mud-crab-scylla-serrata-a-gc-fid-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22523.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">276</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5418</span> Ratio of Omega-6/Omega-3 Fatty Acids in Spelt and Flaxseed Pasta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jelena%20Filipovic">Jelena Filipovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Milenko%20Kosutic"> Milenko Kosutic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dynamic way of life has the tendency to simplify and decrease preparing healthy, quick, cheap and safe meals. Spelt pasta is meeting most of these goals. Contrary to bread, pasta can be stored a long time without deterioration in flavour, odour and usability without losing quality. This paper deals with the chemical composition and content of fatty acids in flaxseed and spelt flour. Ratio of essential fatty acids ω-6/ω-3 is also analysed in spelt pasta and pasta with 0%, 10% and 20% flaxseed flour. Gas chromatography with mass spectrometry is used for carrying out a quantitative analysis of flaxseed flour, spelt flour and pasta liposoluble extracts. Flaxseed flour has a better fatty acid profile than spelt flour, with low levels of saturated fat (approximately 9g/100g), high concentration of linolenic acid (57g/100g) and lower content of linoleic acid (16g/100g), as well as superior ω-6/ω-3 ratio that is 1:4. Flaxseed flour in the share of 10% and 20% in spelt pasta positively contributes to the essential fatty acids daily intake recommended by nutritionists and the improvement of ω-6/ω-3 ratio (6,7:1 and 1:1.2). This paper points out that investigated pasta with flaxseed is a new product with improved functional properties due to high level of ω-3 fatty acids and it is acceptable for consumers in regard to sensory properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flaxseed" title="flaxseed">flaxseed</a>, <a href="https://publications.waset.org/abstracts/search?q=spelt" title=" spelt"> spelt</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=%CF%89-3%2F%CF%89-6%20ratio" title=" ω-3/ω-6 ratio"> ω-3/ω-6 ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=pasta" title=" pasta"> pasta</a> </p> <a href="https://publications.waset.org/abstracts/42864/ratio-of-omega-6omega-3-fatty-acids-in-spelt-and-flaxseed-pasta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42864.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">619</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5417</span> Fatty Acid Composition of Muscle Lipids of Cyprinus carpio L.

FTIR spectrum shows no new peak formation, which confirms negligible amounts of trans-fatty acids. There is a decrease in peroxide value and iodine value, which can be correlated to an increase in saturated fatty acids. The total polyphenolic content was observed to be increased by 20.1% after the treatment. There is an increase in reducing power and DPPH % inhibition of rice bran due to plasma treatment.

Thus, humans have been paying more attention to health, thereby reducing consumption of cholesterol enriched food. Egg is considered as one of the major sources of human dietary cholesterol. However, an alternative way to reduce the potential cholesterolemic effect of eggs is to modify the fatty acid composition of the yolk. The effect of palm oil (PO), soybean oil (SO), sesame seed oil (SSO) and fish oil (FO) supplementation in the diets of layers on egg yolk fatty acid, cholesterol, egg production and egg quality parameters were evaluated in a 42-day feeding trial. One hundred and five Isa Brown laying hens of 34 weeks of age were randomly distributed into seven groups of five replicates and three birds per replicate in a completely randomized design. Seven corn-soybean basal diets (BD) were formulated: BD+No oil (T1), BD+1.5% PO (T2), BD+1.5% SO (T3), BD+1.5% SSO (T4), BD+1.5% FO (T5), BD+0.75% SO+0.75% FO (T6) and BD+0.75% SSO+0.75% FO (T7). Five eggs were randomly sampled at day 42 from each replicate to assay for the cholesterol, fatty acid profile of egg yolk and egg quality assessment. Results showed that there were no significant (P>0.05) differences observed in production performance, egg cholesterol and egg quality parameters except for yolk height, albumen height, yolk index, egg shape index, haugh unit, and yolk colour. There were no significant differences (P>0.05) observed in total cholesterol, high density lipoprotein and low density lipoprotein levels of egg yolk across the treatments. However, diets had effect (P<0.05) on TAG (triacylglycerol) and VLDL (very low density lipoprotein) of the egg yolk. The highest TAG (603.78 mg/dl) and VLDL values (120.76 mg/dl) were recorded in eggs of hens on T4 (1.5% sesame seed oil) and was similar to those on T3 (1.5% soybean oil), T5 (1.5% fish oil) and T6 (0.75% soybean oil + 0.75% fish oil). However, results revealed a significant (P<0.05) variations on eggs’ summation of polyunsaturated fatty acid (PUFA). In conclusion, it is suggested that dietary oils could be included in layers’ diets to produce designer eggs low in cholesterol and high in PUFA especially omega-3 fatty acids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dietary%20oils" title="dietary oils">dietary oils</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20cholesterol" title=" egg cholesterol"> egg cholesterol</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20fatty%20acid%20profile" title=" egg fatty acid profile"> egg fatty acid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=egg%20quality%20parameters" title=" egg quality parameters"> egg quality parameters</a> </p> <a href="https://publications.waset.org/abstracts/39973/effects-of-four-dietary-oils-on-cholesterol-and-fatty-acid-composition-of-egg-yolk-in-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5412</span> Biodiesel Fuel Properties of Mixed Culture Microalgae under Different CO₂ Concentration from Coal Fired Flue Gas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ambreen%20Aslam">Ambreen Aslam</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahira%20Aziz%20Mughal"> Tahira Aziz Mughal</a>, <a href="https://publications.waset.org/abstracts/search?q=Skye%20R.%20Thomas-Hall"> Skye R.

Microalgae produced fatty acid methyl esters (FAMEs) as they can store high levels of lipids without competing for food productivity. After lipid extraction and esterification, fatty acid profile from algae feedstock possessed the abundance of fatty acids with carbon chain length specifically C16 and C18. The qualitative analysis of FAME was done by cultivating mix microalgae consortia under three different CO₂ concentrations (1%, 3%, and 5.5%) from a coal fired flue gas. FAME content (280.3 µg/mL) and productivity (18.69 µg/mL/D) was higher under 1% CO₂ (flue gas) as compare to other treatments. Whereas, Mixed C. (F) supplemented with 5.5% CO₂ (50% flue gas) had higher SFA (36.28%) and UFA (63.72%) which improve the oxidative stability of biodiesel. Subsequently, low Iodine value (136.3 gI₂/100g) and higher Cetane number (52) of Mixed C.+P (F) were found to be in accordance with European (EN 14214) standard under 5.5% CO₂ along with 50mM phosphate buffer. Experimental results revealed that sufficient phosphate reduced FAME productivity but significantly enhance biodiesel quality. This research aimed to develop an integrated approach of utilizing flue gas (as CO₂ source) for significant improvement in biodiesel quality under surplus phosphorus. CO₂ sequestration from industrial flue gas not only reduce greenhouse gases (GHG) emissions but also ensure sustainability and eco-friendliness of the biodiesel production process through microalgae. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel%20analysis" title="biodiesel analysis">biodiesel analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title=" carbon dioxide"> carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=coal%20fired%20flue%20gas" title=" coal fired flue gas"> coal fired flue gas</a>, <a href="https://publications.waset.org/abstracts/search?q=FAME%20productivity" title=" FAME productivity"> FAME productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20profile" title=" fatty acid profile"> fatty acid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20properties" title=" fuel properties"> fuel properties</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20content" title=" lipid content"> lipid content</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20culture%20microalgae" title=" mixed culture microalgae"> mixed culture microalgae</a> </p> <a href="https://publications.waset.org/abstracts/67538/biodiesel-fuel-properties-of-mixed-culture-microalgae-under-different-co2-concentration-from-coal-fired-flue-gas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67538.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">328</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5411</span> Study of Coconut and Babassu Oils with High Acid Content and the Fatty Acids (C6 to C16) Obtained from These Oils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fl%C3%A1vio%20A.%20F.%20da%20Ponte">Flávio A.

This work aims to the physicochemical evaluation of babassu oil (Orbinya speciosa) and coconut (Cocos nucifera) of low quality, as well the obtaining the free fatty acids 6 to 16 carbon atoms, with intention to be used as raw material for the biofuels production. The babassu oil and coconut low quality, as well the fatty acids obtained from these oils were characterized as their physicochemical properties and fatty acid composition (using gas chromatography coupled to mass). The NMR technique was used to assess the efficiency of fractional distillation under reduced pressure to obtain the intermediate carbonic chain fatty acids. The results showed that the bad quality in terms of physicochemical evaluation of babassu oils and coconut oils interfere directly in industrial application. However the fatty acids of intermediate carbonic chain (C6 to C16) may be used in cosmetic, pharmaceutical and particularly as the biokerosene fuel. The chromatographic analysis showed that the babassu oil and coconut oil have as major fatty acids are lauric acid (57.5 and 38.6%, respectively), whereas the top phase from distillation of coconut oil showed caprylic acid (39.1%) and major fatty acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=babassu%20oil%20%28Orbinya%20speciosa%29" title="babassu oil (Orbinya speciosa)">babassu oil (Orbinya speciosa)</a>, <a href="https://publications.waset.org/abstracts/search?q=coconut%20oil%20%28Cocos%20nucifera%29" title=" coconut oil (Cocos nucifera)"> coconut oil (Cocos nucifera)</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a> </p> <a href="https://publications.waset.org/abstracts/48733/study-of-coconut-and-babassu-oils-with-high-acid-content-and-the-fatty-acids-c6-to-c16-obtained-from-these-oils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5410</span> Engineering Escherichia coli for Production of Short Chain Fatty Acid by Exploiting Fatty Acid Metabolic Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamran%20Jawed">Kamran Jawed</a>, <a href="https://publications.waset.org/abstracts/search?q=Anu%20Jose%20Mattam"> Anu Jose Mattam</a>, <a href="https://publications.waset.org/abstracts/search?q=Zia%20Fatma"> Zia Fatma</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Wajid"> Saima Wajid</a>, <a href="https://publications.waset.org/abstracts/search?q=Malik%20Z.%20Abdin"> Malik Z.

In this study, we evaluated the role of fatty acid synthesis and β-oxidation cycle of Escherichia coli to produce butyric acid, a 4-carbon short chain fatty acid, with the help of three thioesterases, i.e., TesAT from Anaerococcus tetradius, TesBF from Bryantella formatexigens and TesBT from Bacteroides thetaiotaomicron. We found that E. coli strain transformed with gene for TesBT and grown in presence of 8 g/L glucose produced maximum butyric acid titer at 1.46 g/L, followed by that of TesBF at 0.85 g/L and TesAT at 0.12 g/L, indicating that these thioesterases were efficiently converting short chain fatty acyl-ACP intermediate of fatty acid synthesis pathway into the corresponding acid. The titer of butyric acid varied significantly depending upon the plasmid copy number and strain genotype. Deletion of genes for fatty acyl-CoA synthetase and acyl-CoA dehydrogenase, which are involved in initiating the fatty acid degradation cycle, and overexpression of FadR, which is a dual transcriptional regulator and exerts negative control over fatty acid degradation pathway, reduced up to 30% of butyric acid titer. This observation suggested that β-oxidation pathway is working synergistically with fatty acid synthesis pathway in production of butyric acid. Moreover, accelerating the fatty acid elongation cycle by overexpressing acetyl-CoA carboxyltransferase (Acc) and 3-hydroxy-acyl-ACP dehydratase (FabZ) or by deleting FabR, the transcription suppressor of elongation, did not improve the butyric acid titer, rather favored the long chain fatty acid production. Finally, a balance between cell growth and butyric acid production was achieved with the use of phosphorous limited growth medium and 14.3 g/L butyric acid, and 17.5 g/L total free fatty acids (FFAs) titer was achieved during fed-batch cultivation. We have engineered an E. coli strain which utilizes the intermediate of both fatty acid synthesis and degradation pathway, i.e. butyryl-ACP and -CoA, to produce butyric acid from glucose. The strategy used in this study resulted in highest reported titers of butyric acid and FFAs in engineered E. coli. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=butenoic%20acid" title="butenoic acid">butenoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=butyric%20acid" title=" butyric acid"> butyric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=Escherichia%20coli" title=" Escherichia coli"> Escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=fed-batch%20fermentation" title=" fed-batch fermentation"> fed-batch fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20chain%20fatty%20acids" title=" short chain fatty acids"> short chain fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=thioesterase" title=" thioesterase"> thioesterase</a> </p> <a href="https://publications.waset.org/abstracts/59240/engineering-escherichia-coli-for-production-of-short-chain-fatty-acid-by-exploiting-fatty-acid-metabolic-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59240.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">371</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5409</span> Characterization of Fatty Acid Glucose Esters as Os9BGlu31 Transglucosidase Substrates in Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juthamath%20Komvongsa">Juthamath Komvongsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bancha%20Mahong"> Bancha Mahong</a>, <a href="https://publications.waset.org/abstracts/search?q=Kannika%20Phasai"> Kannika Phasai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukanya%20Luang"> Sukanya Luang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Seong%20Jeon"> Jong-Seong Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=James%20Ketudat-Cairns"> James Ketudat-Cairns</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Os9BGlu31 is a rice transglucosidase that transfers glucosyl moieties to various acceptors such as carboxylic acids and alcohols, including phenolic acids and flavonoids, in vitro. The role of Os9BGlu31 transglucosidase in rice plant metabolism has not been reported to date. Methanolic extracts of rice bran and flag leaves were found to contain substrates to which Os9BGlu31 could transfer glucose from 4-nitrophenyl β -D-glucopyranoside donor. The semi-purified substrate from rice bran was found to contain oleic acid and linoleic acid and the pure fatty acids were found to act as acceptor substrates for Os9BGlu31 transglucosidase to form 1-O-acyl glucose esters. Os9BGlu31 showed higher activity with oleic acid (18:1) and linoleic acid (18:2) than stearic acid (18:0), and had both higher kcat and higher Km for linoleic than oleic acid in the presence of 8 mM 4NPGlc donor. This transglucosidase reaction is reversible, Os9bglu31 knockout rice lines of flag leaves were found to have higher amounts of fatty acid glucose esters than wild type control lines, these data conclude that fatty acid glucose esters act as glucosyl donor substrates for Os9BGlu31 transglucosidase in rice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title="fatty acid">fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20glucose%20ester" title=" fatty acid glucose ester"> fatty acid glucose ester</a>, <a href="https://publications.waset.org/abstracts/search?q=transglucosidase" title=" transglucosidase"> transglucosidase</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20flag%20leaf" title=" rice flag leaf"> rice flag leaf</a>, <a href="https://publications.waset.org/abstracts/search?q=homologous%20knockout%20lines" title=" homologous knockout lines"> homologous knockout lines</a>, <a href="https://publications.waset.org/abstracts/search?q=tandam%20mass%20spectrometry" title=" tandam mass spectrometry"> tandam mass spectrometry</a> </p> <a href="https://publications.waset.org/abstracts/42160/characterization-of-fatty-acid-glucose-esters-as-os9bglu31-transglucosidase-substrates-in-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42160.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5408</span> Cadaver Free Fatty Acid Distribution Associated with Burial in Mangrove and Oil Palm Plantation Soils under Tropical Climate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siti%20Sofo%20Ismail">Siti Sofo Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Noraina%20Wahida%20Mohd%20Alwi"> Siti Noraina Wahida Mohd Alwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Hafiz%20Ameran"> Mohamad Hafiz Ameran</a>, <a href="https://publications.waset.org/abstracts/search?q=Masrudin%20M.%20Yusoff"> Masrudin M.

However, it requires a lot of man power, costly and time consuming. Therefore, the development of a new method to locate the clandestine graves is urgently needed as the cases involve burial of cadaver in different types of soils under tropical climates are still not well explored. This study focused on the burial in mangrove and oil palm plantation soils, comparing the fatty acid distributions in different soil acidities. A stimulated burial experiment was conducted using domestic pig (Sus scrofa) to substitute human tissues. Approximately 20g of pig fatty flesh was allowed to decompose in mangrove and oil palm plantation soils, mimicking burial in a shallow grave. The associated soils were collected at different designated sampling points, corresponding different decomposition stages. Modified Bligh-Dyer Extraction method was applied to extract the soil free fatty acids. Then, the obtained free fatty acids were analyzed with gas chromatography-flame ionization (GC-FID). A similar fatty acid distribution was observed for both mangrove and oil palm plantations soils. Palmitic acid (C₁₆) was the most abundance of free fatty acid, followed by stearic acid (C₁₈). However, the concentration of palmitic acid (C₁₆) higher in oil palm plantation compare to mangrove soils. Conclusion, the decomposition rate of cadaver can be affected by different type of soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clandestine%20grave" title="clandestine grave">clandestine grave</a>, <a href="https://publications.waset.org/abstracts/search?q=burial" title=" burial"> burial</a>, <a href="https://publications.waset.org/abstracts/search?q=soils" title=" soils"> soils</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acid" title=" free fatty acid"> free fatty acid</a> </p> <a href="https://publications.waset.org/abstracts/87338/cadaver-free-fatty-acid-distribution-associated-with-burial-in-mangrove-and-oil-palm-plantation-soils-under-tropical-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87338.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">399</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5407</span> Oil Extraction from Microalgae Dunalliela sp. by Polar and Non-Polar Solvents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Zonouzi">A.

Nowadays, microalgae are being used as nutrient-dense foods and sources of fine chemicals. They have significant amounts of lipid, carotenoids, vitamins, protein, minerals, chlorophyll, and pigments. Oil extraction from algae is a hotly debated topic currently because introducing an efficient method could decrease the process cost. This can determine the sustainability of algae-based foods. Scientific research works show that solvent extraction using chloroform/methanol (2:1) mixture is one of the efficient methods for oil extraction from algal cells, but both methanol and chloroform are toxic solvents, and therefore, the extracted oil will not be suitable for food application. In this paper, the effect of two food grade solvents (hexane and hexane/ isopropanol) on oil extraction yield from microalgae <em>Dunaliella </em>sp. was investigated and the results were compared with chloroform/methanol (2:1) extraction yield. It was observed that the oil extraction yield using hexane, hexane/isopropanol (3:2) and chloroform/methanol (2:1) mixture were 5.4, 13.93, and 17.5 (% w/w, dry basis), respectively. The fatty acid profile derived from GC illustrated that the palmitic (36.62%), oleic (18.62%), and stearic acids (19.08%) form the main portion of fatty acid composition of microalgae <em>Dunalliela </em>sp. oil. It was concluded that, the addition of isopropanol as polar solvent could increase the extraction yield significantly. Isopropanol solves cell wall phospholipids and enhances the release of intercellular lipids, which improves accessing of hexane to fatty acids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20profile%E2%80%8E" title="fatty acid profile‎">fatty acid profile‎</a>, <a href="https://publications.waset.org/abstracts/search?q=microalgae%E2%80%8E" title=" microalgae‎"> microalgae‎</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20extraction%E2%80%8E" title=" oil extraction‎"> oil extraction‎</a>, <a href="https://publications.waset.org/abstracts/search?q=polar%20solvent%E2%80%8E" title=" polar solvent‎"> polar solvent‎</a> </p> <a href="https://publications.waset.org/abstracts/56505/oil-extraction-from-microalgae-dunalliela-sp-by-polar-and-non-polar-solvents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56505.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">376</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5406</span> The Effect of Different Extraction Techniques on the Yield and the Composition of Oil (Laurus Nobilis L.)

It is a plant native to the southern Mediterranean and widespread in Syria. It is a plant with enormous industrial applications. For instance, they are used as platform chemicals in food, pharmaceutical and cosmetic applications. Herein, we report an efficient extraction of Bay laurel oil from Bay laurel fruits via a comparative investigation of boiled water conventional extraction technique and microwave-assisted extraction (MAE) by microwave heating at atmospheric pressure. In order to optimize the extraction efficiency, we investigated several extraction parameters, such as extraction time and microwave power. In addition, to demonstrate the feasibility of the method, oil obtained under optimal conditions by method (MAE) was compared quantitatively and qualitatively with that obtained by the conventional method. After 1h of microwave-assisted extraction (power of 600W), an oil yield of 9.8% with identified lauric acid content of 22.7%. In comparison, an extended extraction of up to 4h was required to obtain a 9.7% yield of oil extraction with 21.2% of lauric acid content. The change in microwave power impacts the fatty acids profile and also the quality parameters of Laurel Oil. It was found that the profile of fatty acids changed with the power, where the lauric acid content increased from 22.7% at 600W to 30.5% at 1200W owing to a decrease of oleic acid content from 32.8% at 600W to 28.3% at 1200W and linoleic acid content from 22.3% at 600W to 20.6% at 1200W. In addition, we observed a decrease in oil yield from 9.8% at 600W to 5.1% at 1200W. Summarily, the overall results indicated that the extraction of laurel fruit oils could be successfully performed using (MAE) at a short extraction time and lower energy compared with the fixed oil obtained by conventional processes of extraction. Microwave heating exerted more aggressive effects on the oil. Indeed, microwave heating inflicted changes in the fatty acids profile of oil; the most affected fraction was the unsaturated fatty acids, with higher susceptibility to oxidation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwaves" title="microwaves">microwaves</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurel%20oil" title=" Laurel oil"> Laurel oil</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent-free" title=" solvent-free"> solvent-free</a> </p> <a href="https://publications.waset.org/abstracts/163430/the-effect-of-different-extraction-techniques-on-the-yield-and-the-composition-of-oil-laurus-nobilis-l-fruits-widespread-in-syria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163430.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">67</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5405</span> Quantitative on Fatty Acid Profiles, Lipid Contents and Fat-Soluble Vitamin A of Freshwater Fish Species in Tonle Sap Lake, Cambodia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sengly%20Sroy">Sengly Sroy</a>, <a href="https://publications.waset.org/abstracts/search?q=Elodie%20Arnaud"> Elodie Arnaud</a>, <a href="https://publications.waset.org/abstracts/search?q=Adrien%20Servent"> Adrien Servent</a>, <a href="https://publications.waset.org/abstracts/search?q=Sokneang%20In"> Sokneang In</a>, <a href="https://publications.waset.org/abstracts/search?q=Sylvie%20Avallone"> Sylvie Avallone</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Cambodia, fish plays an important role for local community in term of food habits, preference and contribution to several nutritional intakes. Consumed on a daily basis, fishes and their derivatives products are good sources of proteins, essential fatty acids and fat-soluble vitamins. They mainly obtain from the Tonle Sap Lake but, during the last decade, the fish population decreased drastically due to climate change and human activities as well. Contamination by agricultural residues and heavy metals were identified. However, fishes are currently used in several nutrition programs for children and pregnant women to improve their nutritional status. The aim of our work was to characterize the nutritional profile and contamination of 10 fish species consumed near the Tonle Sap Lake with a special attention to fatty acid and fat-soluble vitamin profiles. Fish samples were analyzed for their nutritional profiles (AOAC methods for macronutrients and micronutrients), their lipid content (Folch modified method), their Fatty acid (FAME method), their vitamin A (HPLC) and their heavy metals (ICP-MS). The total lipid contents ranged from 1.43 to 10.00% according to fish species. Lipid profile was mainly dominated by saturated fat (from 47.95 to 57.32%) but some fish species were particularly rich in ω-3 and ω-6 especially eicosapentaenoic acid EPA (3.05%) and docosahexaenoic acid DHA (2.82%). The more the fishes were fats, the more they contained vitamin A, DHA and EPA. Vitamin A is particularly abundant in small fishes (250.10 μg RE/100 g) compare to big ones (13.77 μg RE/100 g) because they are consumed as a whole with their organs (liver) and head. However, the contents of heavy metal in some species are higher than the maximum permitted level (MPL) from codex alimentarius, especially Mn. The results obtained provided important information on the most interesting fish in term of human nutrition and the potential risk of contaminants. The fatty acids are important for child development and pregnant women. These data are useful for supply chain stakeholders and the people in charge of nutrition program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fat-soluble%20vitamin" title="fat-soluble vitamin">fat-soluble vitamin</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title=" fatty acid"> fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=freshwater%20fish" title=" freshwater fish"> freshwater fish</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20content" title=" lipid content"> lipid content</a>, <a href="https://publications.waset.org/abstracts/search?q=Tonle%20Sap%20Lake" title=" Tonle Sap Lake"> Tonle Sap Lake</a> </p> <a href="https://publications.waset.org/abstracts/121341/quantitative-on-fatty-acid-profiles-lipid-contents-and-fat-soluble-vitamin-a-of-freshwater-fish-species-in-tonle-sap-lake-cambodia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5404</span> Lipid from Activated Sludge as a Feedstock for the Production of Biodiesel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ifeanyichukwu%20Edeh">Ifeanyichukwu Edeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Overton"> Tim Overton</a>, <a href="https://publications.waset.org/abstracts/search?q=Steve%20Bowra"> Steve Bowra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is increasing interest in utilising low grade or waste biomass for the production of renewable bioenergy vectors i.e. waste to energy. In this study we have chosen to assess, activated sludge, which is a microbial biomass generated during the second stage of waste water treatment as a source of lipid for biodiesel production. To date a significant proportion of biodiesel is produced from used cooking oil and animal fats. It was reasoned that if activated sludge proved a viable feedstock it has the potential to support increase biodiesel production capacity. Activated sludge was obtained at different times of the year and from two different sewage treatment works in the UK. The biomass within the activated sludge slurry was recovered by filtration and the total weight of material calculated by combining the dry weight of the total suspended solid (TSS) and the total dissolved solid (TDS) fractions. Total lipids were extracted from the TSS and TDS using solvent extraction (Folch methods). The classes of lipids within the total lipid extract were characterised using high performance thin layer chromatography (HPTLC) by referencing known standards. The fatty acid profile and content of the lipid extract were determined using acid mediated-methanolysis to obtain fatty acid methyl esters (FAMEs) which were analysed by gas chromatography and HPTLC. The results showed that there were differences in the total biomass content in the activated sludge collected from different sewage works. Lipid yields from TSS obtained from both sewage treatment works differed according to the time of year (between 3.0 and 7.4 wt. %). The lipid yield varied slightly within the same source of biomass but more widely between the two sewage treatment works. The neutral lipid classes identified were acylglycerols, free fatty acids, sterols and wax esters while the phospholipid class included phosphatidylcholine, lysophosphatidycholine, phosphatidylethanolamine and phosphatidylinositol. The fatty acid profile revealed the presence of palmitic acid, palmitoleic acid, linoleic acid, oleic acid and stearic acid and that unsaturated fatty acids were the most abundant. Following optimisation, the FAME yield was greater than 10 wt. % which was required to have an economic advantage in biodiesel production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20sludge" title="activated sludge">activated sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid" title=" lipid"> lipid</a>, <a href="https://publications.waset.org/abstracts/search?q=methanolysis" title=" methanolysis"> methanolysis</a> </p> <a href="https://publications.waset.org/abstracts/37751/lipid-from-activated-sludge-as-a-feedstock-for-the-production-of-biodiesel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37751.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">472</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5403</span> Changes in Chromatographically Assessed Fatty Acid Profile during Technology of Dairy Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lina%20Lauciene">Lina Lauciene</a>, <a href="https://publications.waset.org/abstracts/search?q=Vaida%20Andruleviciute"> Vaida Andruleviciute</a>, <a href="https://publications.waset.org/abstracts/search?q=Ingrida%20Sinkeviciene"> Ingrida Sinkeviciene</a>, <a href="https://publications.waset.org/abstracts/search?q=Mindaugas%20Malakauskas"> Mindaugas Malakauskas</a>, <a href="https://publications.waset.org/abstracts/search?q=Loreta%20Serniene"> Loreta Serniene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dairy product manufacturers constantly are looking for new markets for their production. And in most cases, the problem of product compliance with the composition requirements of foreign products is highlighted. This is especially true of the composition of milk fat in dairy products. It is well known that there are many factors such as feeding ratio, season, cow breed, stage of lactation that affect the fatty acid composition in milk. However, there is less evidence on the impact of the technological process on the composition of fatty acids in raw milk and products made from it. In this study the influence of the technological process on fat composition in 82% fat butter, 15% fat curd, 3.6% fat yogurt and 2.5% fat UHT milk was determined. The samples were collected at each stage of production, starting with raw milk and ending with the final product in the Lithuanian milk-processing company. Fatty acids methyl esters were quantified using a GC (Clarus 680, Perkin Elmer) equipped with flame ionization detector (FID) and a capillary column SP-2560, 100 m x 0.25 mm id x 0.20 µm. Fatty acids peaks were identified using Supelco® 37 Component FAME Mix. The concentration of each fatty acid was expressed in percent of the total fatty acid amount. In the case of UHT milk production, it was compared raw milk, cream, milk mixture, and UHT milk but significant differences were not estimated between these stages. Analyzing stages of the yogurt production (raw milk, pasteurized milk, and milk with a starter culture and yogurt), no significant changes were detected between stages as well. A slight difference was observed with C4:0 - a percentage of this fatty acid was less (p=0.053) in the final stage than in milk with the starter culture. During butter production, the composition of fatty acids in raw cream, buttermilk, and butter did not change significantly. Only C14:0 decreased in the butter then compared to buttermilk. The curd fatty acid analysis showed the increase of C6:0, C8:0, C10:0, C11:0, C12:0 C14:0 and C17:0 at the final stage when compared to raw milk, cream, milk mixture, and whey. Meantime the increase of C18:1n9c (in comparison with milk mixture and curd) and C18:2n6c (in comparison with raw milk, milk mixture, and curd) was estimated in cream. The results of this study suggest that the technological process did not affect the composition of fatty acids in UHT milk, yogurt, butter, and curd but had the impact on the concentration of individual fatty acids. In general, all of the fatty acids from the raw milk were converted into the final product, only some of them slightly changed the concentration. Therefore, in order to ensure an appropriate composition of certain fatty acids in the final product, producers must carefully choose the raw milk.

The Cassia fistula L. fruit pulp aqueous extract (CFAE) was utilized as a growth medium for cultivation of microalga Chlorella minutissima (C. minutissima). This microalga accumulated a high amount of lipids when cultivated with CFAE as a source of nutrition in comparison to BG-11 medium. Different concentrations (10, 20, 30, 40 and 50%) of CFAE diluted with distilled water were used to cultivate microalga. Effects of light intensity and photoperiod were also observed on biomass and lipid yield of microalga. Light intensity of 8000 lux with a photoperiod of 18 h resulted in maximum biomass and lipid yield of 1.28 ± 0.03 and 0.3968 ± 0.05 g/L, respectively when cultivated with 40% CFAE. Fatty acid methyl ester (FAME) profile of bio-diesel obtained shown the presence of myristic acid (C14:0), palmitic acid (C16:0), palmitoleic acid (C16:1), stearic acid (C18:0), linoleic acid (C18:2), linolenic acid (C18:3), arachidic acid (C20:0), and gondoic acid (C20:1), as major fatty acids.

Thus, this study was conducted to evaluate the efficiency of different extraction methods (Bligh and Dyer, soxhlet, microwave and ultrasonics) on the fat content and fatty acid profiles of marine fish species (Mullus babatus, Upeneus moluccensis, Mullus surmuletus, Anguilla anguilla, Pagellus erythrinus and Saurida undosquamis). Fish species were caught by trawl in Mediterranean Sea and immediately iced. After that, fish were transported to laboratory in ice and stored at -18oC in a freezer until the day of analyses. After extracting lipid from fish by different methods, lipid samples were converted to their constituent fatty acid methyl esters. The fatty acid composition was analysed by a GC Clarus 500 with an autosampler (Perkin Elmer, Shelton, CT, USA) equipped with a flame ionization detector and a fused silica capillary SGE column (30 m x 0.32 mm ID x 0.25 mm BP20 0.25 UM, USA).

For the rapid accumulation of biomass, combined with high productivity of total lipids fraction yield recommended to use the Fitzgerald medium (Scenodesmus obliquus, Oocystis rhomboideus) and/or Bold medium (Dictyochlorella globosa). Productivity of lipids decreased in sequence Dictyochlorella globosa > Scenodesmus obliquus > Oocystis rhomboideus. The bulk of fatty acids fraction of the total lipids is unsaturated fatty acids, which accounts for 70 to 83% of the total number of fatty acids. The share of monoenic acids varies from 16 to 36 %, the share of unsaturated fatty acids - from 44 to 65% of total fatty acids fraction. Among the unsaturated acids dominate α-linolenic acid (C18:3n-3), hexadecatetraenic acid (C16:4) and linoleic acid (C18:2). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgae" title="microalgae">microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=lipids" title=" lipids"> lipids</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=culture%20conditions" title=" culture conditions"> culture conditions</a> </p> <a href="https://publications.waset.org/abstracts/10149/influence-of-culture-conditions-on-the-growth-and-fatty-acid-composition-of-green-microalgae-oocystis-rhomboideus-scenedesmus-obliquus-dictyochlorella-globosa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10149.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5398</span> Fatty Acid Composition, Total Sugar Content and Anti-Diabetic Activity of Methanol and Water Extracts of Nine Different Fruit Tree Leaves Collected from Mediterranean Region of Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sengul%20Uysal">Sengul Uysal</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Zengin"> Gokhan Zengin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdurrahman%20Aktumsek"> Abdurrahman Aktumsek</a>, <a href="https://publications.waset.org/abstracts/search?q=Sukru%20Karatas"> Sukru Karatas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, we determined the total sugar content, fatty acid compositions and α-amylase and α-glucosidase inhibitory activity of methanolic and water extracts of nine different fruit tree leaves. α-amylase and α-glycosidase inhibitory activity were determined by using Caraway-Somogyi–iodine/potassium iodide (IKI) and 4-nitrophenyl-α-D-glucopyranoside (PNPG) as substrate, respectively. Total sugar content of the nine different fruit tree leaves varies from 281.02 mg GE/g (glucose equivalents) to 643.96 mg GE/g. Methanolic extract from avocado leaves had the strongest in α-amylase and α-glucosidase inhibitory activity, 69.21% and 96.26 %, respectively. Fatty acid composition of nine fruit tree leaves was characterized by GC (gas chromatography) and twenty-four components were identified. Among the tested fruit tree leaves, the main component was linolenic acid (49.09%). The level of essential fatty acids are over 50% in mulberry, grape and loquat leaves. PUFAs (polyunsaturated fatty acids) were major group of fatty acids present in oils of mulberry, fig, pomegranate, grape, and loquat leaves. Therefore, these oils can be considered as a good source of polyunsaturated fatty acids. Furthermore, avocado can be regarded as a new source for diabetic therapies. <p class="card-text"><strong>Keywords:</strong> <a
