Abstract The objective of this study was to investigate the volatile and non-volatile compounds of stewed pork with different processing methods (TS: traditional stewing, TSE: traditional stewing with enzymatic degradation, TSEM: traditional stewing with enzymatic degradation and Maillard reaction, HS: high-temperature stewing, HSE: high-temperature stewing with enzymatic degradation, HSEM: high-temperature stewing with enzymatic degradation and Maillard reaction). The odor compounds results showed that HS, HSE and HSEM had higher types and contents of volatile compounds than TS, TSE and TSEM, especially HSEM. All stewed pork from traditional and high-temperature stewing methods were classified into two groups using an electronic nose due to different flavor characteristics. Non-volatile compounds results displayed the contents of total amino acids in HS, HSE and HSEM were higher significantly (P
