in this study, the oil yield, fatty acid (fa) composition and the physicochemical and quality characteristics of salvia macrosiphon crude seed oil were determined. the main fatty acids ranked in the following order of abundance: α- linolenic acid> linoleic acid> oleic acid. the n3 /n6 fa ratio and polyunsaturated fa/ saturated fa ratio were 1.6 and 7.23, respectively. the fa composition reveale...

seasonal variation of fatty acids composition of milk and various milk products have been subjected to many investigations.however ,most of the researches are concerned with a single product and apparantly there is no inforation about the extent and the factors which contribute to changes in fatty acids composition of lipids in the process of ghee-making by the  traditional methods.thus compara...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P<0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fat,...

lipids play an important role in maintaining human health. thermal process cause to changes in nutritional value as well as changes in the profile of fatty acids in fish. the aim of this study was to evaluate the effect of frying on chemical composition and profile of fatty acids is fish shaary. for doing this project, 10 kg of the fish were purchased from the market of behbahan and with ice we...

Background: Mastitis in sheep caused by Staphylococcus spp. is a serious concern for dairy farming. Aims: The objective of this study was to evaluate the impact of the intramammary infection (IMI) caused by Staphylococcus spp. on the long-chain fatty acid profile and composition of ewe’s milk. Methods: The experiment was conducted in a herd of Zoslachtena Valaska sheep. Half-udder milk samples ...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

Maternal adipose tissue is a major contributor to breast milk long-chain fatty acids, probably through the pool of plasma NEFA. The fatty acid composition of the erythrocyte membrane (EM) is a biochemical index of the intake of fatty acids not synthesized endogenously and of PUFA and long-chain PUFA fatty acid status. The present study investigated the associations between breast milk fatty aci...

  Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil .  Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...

hydrogenation of oils might be considered as the largest reaction in the edible oil industry. the reaction consists of the addition of hydrogen at the double bounds of fatty acids. although for some reasons this might be considered a desirable reaction but for some others it might create problems in the food and nutrition chain circle due to the formation of saturated and trans fatty acids. soy...
