Fish spoilage bacteria produced all biogenic amine tested, mainly histamine and serotonin. Ammonia was accumulated more than 13.60 mg/L. Histamine production was in range 37.50 mg/L by Ser. liquefaciens and 86.71 mg/L by Ent. cloacae. The highest putrescine and cadaverine production was observed by Ent. cloacae (17.80 vs. 17.69 mg/L). The presence of OL, OC and BW in the broth significantly affected biogenic amine accumulation by bacteria. The antibacterial effect of olive by products depended on bacterial strains. OL and OC resulted in significant inhibition effect on HIS accumulation by bacteria apart from Ser. liquefaciens and Prot. mirabilis. The study result revealed that usefulness of OL and OC to prevent the accumulation of this amine which may affect human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antimicrobials" title="Antimicrobials">Antimicrobials</a>, <a href="https://publications.waset.org/abstracts/search?q=biogenic%20amine" title=" biogenic amine"> biogenic amine</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20spoilage%20bacteria" title=" fish spoilage bacteria"> fish spoilage bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=olive-by%20products" title=" olive-by products"> olive-by products</a> </p> <a href="https://publications.waset.org/abstracts/19395/ammonia-and-biogenic-amine-production-of-fish-spoilage-bacteria-affected-by-olive-leaf-olive-cake-and-black-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19395.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">502</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">9</span> The Effects of Nanoemulsions Based on Commercial Oils: Sunflower, Canola, Corn, Olive, Soybean, and Hazelnut Oils for the Quality of Farmed Sea Bass at 2卤2掳C</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Ozogul">Yesim Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Durmu%C5%9F"> Mustafa Durmu艧</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Ozogul"> Fatih Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmeray%20Kuley%20Bo%C4%9Fa"> Esmeray Kuley Bo臒a</a>, <a href="https://publications.waset.org/abstracts/search?q=Y%C4%B1lmaz%20U%C3%A7ar"> Y谋lmaz U莽ar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatice%20Yazgan"> Hatice Yazgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of oil-in-water nanoemulsions on the sensory, chemical (total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBA), peroxide value (PV) and free fatty acids (FFA), and microbiological qualities (total viable count (TVC), total psychrophilic bacteria, and total Enterbactericaea bacteria) of sea bream fillets stored at 2 卤 2掳C were investigated. Physical properties of emulsions (viscosity, the particle size of droplet, thermodynamic stability, refractive index and surface tension) were determined. The results showed that the use of nanoemulsion extended the shelf life of fish 2 days when compared with the control. Treatment with nanoemulsions significantly (p<0.05) decreased the values of biochemical parameters during storage period. Bacterial growth was inhibited by the use of nanoemulsions. Based on the results, it can be concluded that nanoemulsions based on commercial oils extended the shelf life and improved the quality of sea bass fillets during storage period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipid%20oxidation" title="lipid oxidation">lipid oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoemulsion" title=" nanoemulsion"> nanoemulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20bass" title=" sea bass"> sea bass</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20parameters" title=" quality parameters "> quality parameters </a> </p> <a href="https://publications.waset.org/abstracts/19018/the-effects-of-nanoemulsions-based-on-commercial-oils-sunflower-canola-corn-olive-soybean-and-hazelnut-oils-for-the-quality-of-farmed-sea-bass-at-22c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19018.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">479</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">8</span> The Impact of the Cell-Free Solution of Lactic Acid Bacteria on Cadaverine Production by Listeria monocytogenes and Staphylococcus aureus in Lysine-Decarboxylase Broth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20%C3%96zogul">Fatih 脰zogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurten%20Toy"> Nurten Toy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20%C3%96zogul"> Yesim 脰zogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The influences of cell-free solutions (CFSs) of lactic acid bacteria (LAB) on cadaverine and other biogenic amine production by Listeria monocytogenes and Staphylococcus aureus were investigated in lysine decarboxylase broth (LDB) using HPLC. Cell-free solutions were prepared from Lactococcus lactis subsp. lactis, Leuconostoc mesenteroides subsp. cremoris, Pediococcus acidophilus and Streptococcus thermophiles. Two different concentrations that were 50% and 25% CFS and the control without CFSs were prepared. Significant variations on biogenic amine production were observed in the presence of L. monocytogenes and S. aureus (P<0.05). The role of CFS on biogenic amine production by foodborne pathogens varied depending on strains and specific amine. Cadaverine formation in control by L. monocytogenes and S. aureus were 500.9 and 948.1 mg/L, respectively while the CFSs of LAB induced 4-fold lower cadaverine production by L. monocytogenes and 7-fold lower cadaverine production by S. aureus. CFSs resulted in strong decreases in cadaverine and putrescine production by L. monocytogenes and S. aureus, although remarkable increases were observed for histamine, spermidine, spermine, serotonin, dopamine, tyramine, and agmatine, in the presence of LAB in lysine decarboxylase broth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell-free%20solution" title="cell-free solution">cell-free solution</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=cadaverine" title=" cadaverine"> cadaverine</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20borne-pathogen" title=" food borne-pathogen"> food borne-pathogen</a> </p> <a href="https://publications.waset.org/abstracts/19420/the-impact-of-the-cell-free-solution-of-lactic-acid-bacteria-on-cadaverine-production-by-listeria-monocytogenes-and-staphylococcus-aureus-in-lysine-decarboxylase-broth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19420.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">541</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">7</span> The Ability of Organic Acids Production by Lactic Acid Bacteria in M17 Broth and Squid, Shrimp, Octopus, Eel Infusion Broth </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20%C3%96zogul">Fatih 脰zogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Sezen%20%C3%96z%C3%A7eli%CC%87k"> Sezen 脰z莽eli虈k</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20%C3%96zogul"> Yesim 脰zogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lactic, acetic, succinic, propionic, formic and butyric acid production by lactic acid bacteria (LAB) were monitored in M17 broth (the control) and some fish (squid, shrimp, octopus, and eel) infusion broth by using HPLC method. There were significant differences in terms of lactic, acetic, succinic, propionic, formic and butyric acid production (p < 0.005) among bacterial strains. Acetic acid production was the lowest by LAB while succinic acid followed by propionic acid was synthesized at the highest levels. Lactic acid production ranged from 0 to 938 mg/L by all LAB strains in different infusion broth. The highest acetic acid production was found by Lb. acidophilus and Lb. delbrueckii subsp. lactic in octopus and shrimp infusion broth, with values of 872 and 674 mg/L, respectively while formic acid formation ranged from 1747 mg/L by Lb. acidophilus in octopus infusion broth to 69 mg/L by Lb. delbrueckii subsp. lactis in shrimp infusion broth. Propionic acid and butyric acid productions by St. thermophilus were 9852 and 3999 mg/L in shrimp infusion broth while Leu. mes. subsp. cremoris synthesized 312 and 9 mg/L of those organic acid in European squid infusion broth, respectively. Apparently, LAB strains had a great capability to generate succinic acid followed by propionic and butyric acid. In addition, other organic acid production differed significantly depending on bacterial strains and growth medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lactic%20acid%20bacteria" title="Lactic acid bacteria ">Lactic acid bacteria </a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20acid" title=" organic acid"> organic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=HPLC%20analysis" title=" HPLC analysis"> HPLC analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20medium" title=" growth medium"> growth medium</a> </p> <a href="https://publications.waset.org/abstracts/72696/the-ability-of-organic-acids-production-by-lactic-acid-bacteria-in-m17-broth-and-squid-shrimp-octopus-eel-infusion-broth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72696.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">385</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">6</span> The Effects of Extraction Methods on Fat Content and Fatty Acid Profiles of Marine Fish Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yesim%20%C3%96zogul">Yesim 脰zogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Fethiye%20Takada%C5%9F"> Fethiye Takada艧</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Durmus"> Mustafa Durmus</a>, <a href="https://publications.waset.org/abstracts/search?q=Y%C4%B1lmaz%20Ucar"> Y谋lmaz Ucar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20R%C4%B1za%20K%C3%B6%C5%9Fker"> Ali R谋za K枚艧ker</a>, <a href="https://publications.waset.org/abstracts/search?q=Gulsun%20%C3%96zyurt"> Gulsun 脰zyurt</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20%C3%96zogul"> Fatih 脰zogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been well documented that polyunsaturated fatty acids (PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have beneficial effects on health, regarding prevention of cardiovascular diseases, cancer and autoimmune disorders, development the brain and retina and treatment of major depressive disorder etc. Thus, an adequate intake of omega PUFA is essential and generally marine fish are the richest sources of PUFA in human diet. 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). The results showed that there were significant differences (P < 0.05) in fatty acids of all species and also extraction methods affected fat contents and fatty acid profiles of fish species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction%20methods" title="extraction methods">extraction methods</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=marine%20fish" title=" marine fish"> marine fish</a>, <a href="https://publications.waset.org/abstracts/search?q=PUFA" title=" PUFA"> PUFA</a> </p> <a href="https://publications.waset.org/abstracts/72687/the-effects-of-extraction-methods-on-fat-content-and-fatty-acid-profiles-of-marine-fish-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72687.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">267</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">5</span> Purification of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) from Fish Oil Using HPLC Method and Investigation of Their Antibacterial Effects on Some Pathogenic Bacteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y%C4%B1lmaz%20U%C3%A7ar">Y谋lmaz U莽ar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Ozogul"> Fatih Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Durmu%C5%9F"> Mustafa Durmu艧</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Ozogul"> Yesim Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20R%C4%B1za%20K%C3%B6%C5%9Fker"> Ali R谋za K枚艧ker</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmeray%20Kuley%20Bo%C4%9Fa"> Esmeray Kuley Bo臒a</a>, <a href="https://publications.waset.org/abstracts/search?q=Deniz%20Ayas"> Deniz Ayas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), that are essential oils from trout oil, using high-performance liquid chromatography (HPLC) method, bioconverted EPA and DHA into bioconverted EPA (bEPA), bioconverted DHA (bDHA) extracts by P. aeruginosa PR3. Moreover, in vitro antibacterial activity of bEPA and bDHA was investigated using disc diffusion methods and minimum inhibitory concentration (MIC). EPA and DHA concentration of 11.1% and 15.9% in trout oil increased in 58.64% and 40.33% after HPLC optimisation, respectively. In this study, EPA and DHA enriched products were obtained which are to be used as valuable supplements for food and pharmaceutical purposes. The bioconverted EPA and DHA exhibited antibacterial activities against two Gram-positive bacteria (Listeria monocytogenes ATCC 7677 and Staphylococcus aureus ATCC 29213) and six Gram-negative bacteria (Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC700603, Enterococcus faecalis ATCC 29212, Aeromonas hydrophila NCIMB 1135, and Salmonella Paratyphi A NCTC 13). Inhibition zones and MIC value of bEPA and bDHA against bacterial strains ranged from 7 to 12 mm and from 350 to 2350 渭g/mL, respectively. Our results suggested that the crude extracts of bioconversion of EPA and DHA by P. aeruginosa PR3 can be considered as promising antimicrobials in improving food safety by controlling foodborne pathogens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=High-Performance%20Liquid%20Chromatography%20%28HPLC%29" title="High-Performance Liquid Chromatography (HPLC)">High-Performance Liquid Chromatography (HPLC)</a>, <a href="https://publications.waset.org/abstracts/search?q=docosahexaenoic%20acid" title=" docosahexaenoic acid"> docosahexaenoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=DHA" title=" DHA"> DHA</a>, <a href="https://publications.waset.org/abstracts/search?q=eicosapentaenoic%20acid" title=" eicosapentaenoic acid"> eicosapentaenoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=EPA" title=" EPA"> EPA</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20inhibitory%20concentration" title=" minimum inhibitory concentration"> minimum inhibitory concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=MIC" title=" MIC"> MIC</a>, <a href="https://publications.waset.org/abstracts/search?q=Pseudomonas%20aeruginosa%20PR3" title=" Pseudomonas aeruginosa PR3"> Pseudomonas aeruginosa PR3</a> </p> <a href="https://publications.waset.org/abstracts/21883/purification-of-eicosapentaenoic-acid-epa-and-docosahexaenoic-acid-dha-from-fish-oil-using-hplc-method-and-investigation-of-their-antibacterial-effects-on-some-pathogenic-bacteria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21883.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">498</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">4</span> Antimicrobial Functions of Some Spice Extracts Such as Sumac, Cumin, Black Pepper and Red Pepper on the Growth of Common Food-Borne Pathogens and Their Biogenic Amine Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatih%20%C3%96zogul">Fatih 脰zogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Esmeray%20Kuley%20Boga"> Esmeray Kuley Boga</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferhat%20Kuley"> Ferhat Kuley</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20%C3%96zogul"> Yesim 脰zogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The impact of diethyl ether extract of spices (sumac, cumin, black pepper and red pepper) on growth of Staphylococcus aureus, Salmonella Paratyphi A, Klebsiella pneumoniae, Enterococcus faecalis, Camplylobacter jejuni, Aeromonas hydrophila, Pseudomonas aeruginosa and Yersinia enterocolitica and their biogenic amine production were investigated in tyrosine decarboxylase broth. Sumac extract generally had the highest activity to inhibit bacterial growth compared to other extracts, although antimicrobial effect of extracts used varied depending on bacterial strains. Sumac extract resulted in 3.34 and 2.54 log reduction for Y. enterocolitica and Camp. jejuni growth, whilst red pepper extract induced 0.65, 0.41 and 0.34 log reduction for growth of Y. enterocolitica, S. Paratyphi A and Staph. aureus, respectively. Spice extracts significantly inhibited ammonia production by bacteria (P < 0.05). Eleven and nine fold reduction on ammonia production by S. Paratyphi A and Staph. aureus were observed in the presence of sumac extract. Dopamine, agmatine, tyramine, serotonin and TMA were main amines produced by bacteria. Tyramine production by food-borne-pathogens was more than 10 mg/L, whereas histamine accumulated below 52 mg/L. The effect of spice extracts on biogenic amine production varied depending on amino acid decarboxylase broth, spice type, bacterial strains and specific amine, although cumin extract generally increased biogenic amine production by bacteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobials" title="antimicrobials">antimicrobials</a>, <a href="https://publications.waset.org/abstracts/search?q=biogenic%20amines" title=" biogenic amines"> biogenic amines</a>, <a href="https://publications.waset.org/abstracts/search?q=food-borne%20pathogens" title=" food-borne pathogens"> food-borne pathogens</a>, <a href="https://publications.waset.org/abstracts/search?q=spice%20extracts" title=" spice extracts"> spice extracts</a> </p> <a href="https://publications.waset.org/abstracts/72668/antimicrobial-functions-of-some-spice-extracts-such-as-sumac-cumin-black-pepper-and-red-pepper-on-the-growth-of-common-food-borne-pathogens-and-their-biogenic-amine-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72668.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">312</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">3</span> The Effects of Nanoemulsions Based on Commercial Oils for the Quality of Vacuum-Packed Sea Bass at 2卤2掳C</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Durmu%C5%9F">Mustafa Durmu艧</a>, <a href="https://publications.waset.org/abstracts/search?q=Yesim%20Ozogul"> Yesim Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Esra%20Bal%C4%B1kc%C4%B1"> Esra Bal谋kc谋</a>, <a href="https://publications.waset.org/abstracts/search?q=Saadet%20Gokdo%C4%9Fan"> Saadet Gokdo臒an</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Ozogul"> Fatih Ozogul</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20R%C4%B1za%20K%C3%B6%C5%9Fker"> Ali R谋za K枚艧ker</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%B0lknur%20Yuvka"> 陌lknur Yuvka </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food scientists and researchers have paid attention to develop new ways for improving the nutritional value of foods. The application of nanotechnology techniques to the food industry may allow the modification of food texture, taste, sensory attributes, coloring strength, processability, and stability during shelf life of products. In this research, the effects of nanoemulsions based on commercial oils for vacuum-packed sea bass fillets stored at 2卤2掳C were investigated in terms of the sensory, chemical (total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBA), peroxide value (PV) and free fatty acids (FFA), pH, water holding capacity (WHC)) and microbiological qualities (total anaerobic bacteria and total lactic acid bacteria). Physical properties of emulsions (viscosity, the particle size of droplet, thermodynamic stability, refractive index, and surface tension) were determined. Nanoemulsion preparation method was based on high energy principle, with ultrasonic homojenizator. Sensory analyses of raw fish showed that the demerit points of the control group were found higher than those of treated groups. The sensory score (odour, taste and texture) of the cooked fillets decreased with storage time, especially in the control. Results obtained from chemical and microbiological analyses also showed that nanoemulsions significantly (p<0.05) decreased the values of biochemical parameters and growth of bacteria during storage period, thus improving quality of vacuum-packed sea bass. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20parameters" title="quality parameters">quality parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoemulsion" title=" nanoemulsion"> nanoemulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20bass" title=" sea bass"> sea bass</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title=" shelf life"> shelf life</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20packing" title=" vacuum packing "> vacuum packing </a> </p> <a href="https://publications.waset.org/abstracts/30150/the-effects-of-nanoemulsions-based-on-commercial-oils-for-the-quality-of-vacuum-packed-sea-bass-at-22c" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30150.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">459</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">2</span> The Use of Thermal Infrared Wavelengths to Determine the Volcanic Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Levent%20Basayigit">Levent Basayigit</a>, <a href="https://publications.waset.org/abstracts/search?q=Mert%20Dedeoglu"> Mert Dedeoglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadime%20Ozogul"> Fadime Ozogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, an application was carried out to determine the Volcanic Soils by using remote sensing. &nbsp;The study area was located on the Golcuk formation in Isparta-Turkey. The thermal bands of Landsat 7 image were used for processing. The implementation of the climate model that was based on the water index was used in ERDAS Imagine software together with pixel based image classification. Soil Moisture Index (SMI) was modeled by using the surface temperature (Ts) which was obtained from thermal bands and vegetation index (NDVI) derived from Landsat 7. Surface moisture values were grouped and classified by using scoring system. Thematic layers were compared together with the field studies. Consequently, different moisture levels for volcanic soils were indicator for determination and separation. Those thermal wavelengths are preferable bands for separation of volcanic soils using moisture and temperature models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Landsat%207" title="Landsat 7">Landsat 7</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20moisture%20index" title=" soil moisture index"> soil moisture index</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20models" title=" temperature models"> temperature models</a>, <a href="https://publications.waset.org/abstracts/search?q=volcanic%20soils" title=" volcanic soils"> volcanic soils</a> </p> <a href="https://publications.waset.org/abstracts/68582/the-use-of-thermal-infrared-wavelengths-to-determine-the-volcanic-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68582.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">305</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">1</span> Valorization of Seafood and Poultry By-Products as Gelatin Source and Quality Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elif%20Tugce%20Aksun%20Tumerkan">Elif Tugce Aksun Tumerkan</a>, <a href="https://publications.waset.org/abstracts/search?q=Umran%20Cansu"> Umran Cansu</a>, <a href="https://publications.waset.org/abstracts/search?q=Gokhan%20Boran"> Gokhan Boran</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatih%20Ozogul"> Fatih Ozogul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gelatin is a mixture of peptides obtained from collagen by partial thermal hydrolysis. It is an important and useful biopolymer that is used in the food, pharmacy, and photography products. Generally, gelatins are sourced from pig skin and bones, beef bone and hide, but within the last decade, using alternative gelatin resources has attracted some interest. In this study, functional properties of gelatin extracted from seafood and poultry by-products were evaluated. For this purpose, skins of skipjack tuna (Katsuwonus pelamis) and frog (Rana esculata) were used as seafood by-products and chicken skin as poultry by-product as raw material for gelatin extraction. Following the extraction of gelatin, all samples were lyophilized and stored in plastic bags at room temperature. For comparing gelatins obtained; chemical composition, common quality parameters including bloom value, gel strength, and viscosity in addition to some others like melting and gelling temperatures, hydroxyproline content, and colorimetric parameters were determined. The results showed that the highest protein content obtained in frog gelatin with 90.1% and the highest hydroxyproline content was in chicken gelatin with 7.6% value. Frog gelatin showed a significantly higher (P < 0.05) melting point (42.7掳C) compared to that of fish (29.7掳C) and chicken (29.7掳C) gelatins. The bloom value of gelatin from frog skin was found higher (363 g) than chicken and fish gelatins (352 and 336 g, respectively) (P < 0.05). While fish gelatin had higher lightness (L*) value (92.64) compared to chicken and frog gelatins, redness/greenness (a*) value was significantly higher in frog skin gelatin. Based on the results obtained, it can be concluded that skins of different animals with high commercial value may be utilized as alternative sources to produce gelatin with high yield and desirable functional properties. Functional and quality analysis of gelatin from frog, chicken, and tuna skin showed by-product of poultry and seafood can be used as an alternative gelatine source to mammalian gelatine. The functional properties, including bloom strength, melting points, and viscosity of gelatin from frog skin were more admirable than that of the chicken and tuna skin. Among gelatin groups, significant characteristic differences such as gel strength and physicochemical properties were observed based on not only raw material but also the extraction method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken%20skin" title="chicken skin">chicken skin</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20skin" title=" fish skin"> fish skin</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20industry" title=" food industry"> food industry</a>, <a href="https://publications.waset.org/abstracts/search?q=frog%20skin" title=" frog skin"> frog skin</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20strength" title=" gel strength"> gel strength</a> </p> <a href="https://publications.waset.org/abstracts/94003/valorization-of-seafood-and-poultry-by-products-as-gelatin-source-and-quality-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94003.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">163</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">&copy;
