چکیده مقاله:
Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to ۳۶, ۴۶, ۴۵ and ۴۵ compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectively. Total concentrations of volatile had increased from ۷۲.۸۰ to ۱۱۱.۰۶, ۷۴.۲۵, ۱۱۲.۱۹ and ۹۲.۳۷ μg/kg, respectively. The concentration and new flavor compounds were increased by chill-reheating, due to the fast oxidation. The concentration of alcohol and aldehydes increased significantly (P<۰.۰۵). The hexanal amount also increased in all samples and indicated a marked development of warmed-over flavor. Quantitative and qualitative (P<۰.۰۵) differences were observed in volatile compounds between raw and cooked samples.
