Effects of frying by different frying oils on fatty acid profile of silver carp (Hypophthalmichthys molitrix)

 The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p<۰.۰۵) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-۳ fatty acids. Frying by sunflower oil increased PUFA significantly (p<۰.۰۵), which caused to decrease in SFA and MUFA. The ω-۶/ω-۳ ratio of control samples (۰.۲۲۴) after shallow fat frying and deep frying, increased to ۱.۲۸۷ and ۰.۶۱۵ to ۲.۲۹۰ and ۱.۵۳۸ and to ۹.۳۸۱ and ۵.۹۵۰ by olive oil, canola oil and sunflower oil, respectively. Results suggest that frying oil can change the fatty acid composition of fish. The changes are depending to the kind of frying oil and method of frying which used.
