Abstract：In order to investigate the effects of direct reheating，water bath reheating，microwave reheating and steam reheating on the flavor of Sichuan cuisine twice-cooked pork，in this study，the flavor characteristics of twice-cooked pork treated by four reheating methods are systematically analyzed by combining electronic nose and electronic tongue in inteligent sensory technology with amino acid analyzer and headspace gas chromatographyion mobility spectrometry （HS-GC-IMS）.The results indicate that electronic nose and electronic tongue can effectively identify the aroma and taste characteristics of twice-cooked pork. Microwave reheating significantlyenhances thenutritional valueof twice-cooked pork.A total of17 freeamino acids are detected，and the content of total free amino acids in the twice-cooked pork treated by microwave reheating reaches the highest of （202.08±6.68）mg/g . The partial least squares discriminant analysis （PLS-DA） model shows that the flavor difference between direct reheating and steam reheating is the most significant. According to variable importance in projection （VIP） value，22 key diferential aroma substances are screened， including 1-penten-3-ol，cis-2-pentenol and so on，which can be used as volatile markers to distinguish the aroma characteristics of twice-cooked pork by different reheating methods. This study has provided an important theoretical basis for reheating method of twice-cooked pork and provided data support for the further exploration of effect of different reheating methods on the flavor of twice-cooked pork.
