The study showed that Sous-vide (SV) cooking improved the quality and digestion characteristics of braised pork, with lower fat content and malondialdehyde value compared to traditional cooking methods. SV samples had higher protein content and total sulfhydryl content, indicating potential health benefits. Additionally, SV cooking produced bioactive and antioxidant peptides, along with similar flavor compounds to traditional cooking methods.
This study aimed to evaluate the effect of Sous-vide (SV) cooking on the quality, flavor and digestion characteristics of braised pork. Traditional (TD) sample had the highest fat content and malondialdehyde (MDA) value, but the lowest protein content and total sulfhydryl (SH) content (P < 0.05). The SH content in SV samples decreased with the heating time, but MDA content increased (P < 0.05). In addition, alpha-helix content of TD samples was higher but beta-sheet content was lower than SV samples. LC-MS/MS indicated that SV samples at 65 degrees C for 8 h had potential bioactive and antioxidant peptides. GC-MS mainly identified 395 volatile components and SV samples at 70 degrees C for 8 h and 75 degrees C for 8 h had similar flavor compounds to TD samples. Thus, Sous-vide cooking produced better quality and digestion characteristics of braised pork. These findings give a new insight into the associations of processing methods with meat quality.
