In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The ...

By the reaction of furan-2-carboxylic acids and furfural with diazonium salts 1a-j arylfuran-2-carboxylic 4a-e 5-arylfuran-2-carbaldehydes 5a-f were synthesized. Acids transformed into appropriated acylchlorides 6a-e used for preparation 4-(5-aryl-2-furoyl)morpholines 7a-e . 4-[(5-Aryl-2-furyl)carbonothioyl]morpholines 8a-f prepared from aldehydes by using Willgerodt-Kindler reaction. The struc...

low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. it was thought that the hplc is the best method of the determination of organic acids in the apple juice. in this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extr...

The aim of this study was to evaluate gastrointestinal microbial population response and performance of broiler chickens fed organic acids and silver nanoparticles coated on zeolite under heat stress condition. In this experiment, 375 one-day old broiler chicks (Cobb 500) were randomly divided into 5 treatments containing 5 replicates with 15 birds in each replicate. Five dietary treatments wer...

objective: to modify yeild of milk fat and to improve fatty acids profile of milk fat with supplementation of the diet with fish oil enrich in omega-3 fatty acids, especially, eicosapentaenoic acid (epa) and docosahexaenoic acid (dha). design: clinical trial. animals: ten dairy cows (treatment group, n=5 and control group, n=5). procedure: different amounts of fish oil were fed to the treatment...

milk fat is frequently adulterated to meet the demand which exceeds the supply and to increase profit margins. samples of butter adulterated with different levels (5, 10 and 15% w/w) of margarine were prepared and analysed using different methods including refractive index, iodine, reichert-meissl and polenske values. gc and hplc were utilized to determine fatty acid and tocol profiles of sampl...
