摘要
The effect of frying on fatty acid profile, free amino acids and volatile compounds of grass carp (Ctenopharyngodon idellus) fillets was investigated by comparing two frying time points (2 and 4 min). Although frying decreased overall fatty acid content with different degree of degradation between the two frying time points, the content of C18: 2 n-6 and C18: 3 n-3 was significantly increased (P<0.05). By contrast, the total free amino acids content increased from 53.36 nmol/kg in raw to 65.03 and 72.18 nmol/kg in samples fried for 2 and 4 min, respectively. It appeared that frying likely increased the content and number of volatiles since 13 and 4 novel volatiles were formed during 0-2 and 2-4 min of frying, respectively. It can be concluded that frying improves the taste and flavor of food, but decreases the nutritional value of grass carp fillets to some extent.
