the effects of different cooking methods (deep fat frying, boiling and steaming) on lipid content and fatty acid composition of grass carp ( ctenopharyngodon idella ) fillets during chill storage were investigated. fillet samples were cooked and then stored at + 4°c for 4 days. the control and the cooked fillet samples were analyzed for their chemical characteristics. twelve fatty acids were id...

The biosynthetic pathways of saturated and unsaturated fatty acids consist of many steps controlled by various enzymes. One of the methods for improving oil quality is to change the fatty acid profile through genetic manipulation which requires isolation and characterization of the genes and other cis-acting elements, such as the promoter, involved in fatty acid biosynthesis. b-ketoacyl-CoA syn...

In this study rainbow trout (Oncorhynchus mykiss) fillets were vacuum packed, frozen and stored at -18°C and  the effect of this packaging method on proximate composition, fatty acids and amino acid profile and their changes compared to control conditions during 9 months of storage were studied. The results showed that 18 fatty acids were identified. The unsaturated fatty acid (UFA) were 56.77 ...

abstract: olives belong to the family of olea europaea l. is a popular fruit tree. the fruit and the oil extracted from it is consumed worldwide particularly in the mediterranean regions. in this study changes in the fatty acid composition of the oil extracted from olive fruit during the course of maturation is investigated. this work is concerned with the best harvesting point when oleic acid ...

an 8-week feeding experiment was carried out on beluga (huso huso) juvenile to evaluate the effects of different levels of fish oil containing n-3 highly unsaturated fatty acids (n-3 hufas) on fish growth and fatty acid composition. the requirements of beluga juvenile for n-3 hufas were studied by feeding fish diets containing six different levels of n-3 hufas ranging from 1.56 to 17.25% (% of ...

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr...
