modifications in fat and fatty acid composition of silver carp that take place at each stage of canning process (precooking and sterilization) were evaluated. results showed, precooking led to decrease total fat and increase conjugated dines. the amounts of free fatty acids and thiobarbituric acids had no changed during precooking but these compounds like conjugated dine were increased after st...

This study was conducted to find the effects of fruit ripening and extraction method on the quantity and quality of the Koroneiki olive oil. The oil samples extracted in six ripening stages were used for further quality analysis. Quality assessment of the oil was conducted according to the standard methods and the composition of fatty acids was measured by gas chromatography. The results showed...

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...

ten varieties of iranian soybeans are cultivated in different areas of the country; persia or sahar (sr), hill (hl), williams (wz), gorgan 3 (gn), clarke (kl), hawkey (hk), zaan (zn), harcor (hr), dare (dr) and simes (ss), grown in tropical regions. samples of these 10 varieties were obtained from the institute of plant and seed research. after sample preparation, their oils were extracted and ...

Introduction: Nonalcoholic fatty liver disease (NAFLD) is a global disease which its prevalence is about 10-35%. Several factors are involved in the pathogenesis of the disease. The present study was conducted to evaluate the effect of fasting during Ramadan on plasma free fatty acids in patients with NAFLD.Methods: This cross-sectional study was performed during the month of Ramadan in June-Ju...

Biodiesel is an alternative fuel for diesel engines consisting of the alkyl monoesters of fatty acids from vegetable oils or animal fats. Most of the biodiesel that is currently made uses soybean oil, methanol, and an alkaline catalyst. The high value of soybean oil as a food product makes production of a cost–effective fuel very challenging. However, there are large amounts of low–cost oils an...

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...
