Effect of Ligilactobacillus salivarius M18-6 on Flavor Quality and Antioxidant Activity of Fermented Soymilk

In this study, the effect of Ligilactobacillus salivarius M18-6, with the capability to stably and rapidly ferment soybean protein and strong antioxidant capacity, on the flavor quality and antioxidant activity of fermented soymilk was analyzed. This study found that with increasing fermentation tim...

description In this study, the effect of Ligilactobacillus salivarius M18-6, with the capability to stably and rapidly ferment soybean protein and strong antioxidant capacity, on the flavor quality and antioxidant activity of fermented soymilk was analyzed. This study found that with increasing fermentation time, soybean protein and fat gradually decomposed, and the particle size of fermented soymilk showed a downward trend, making its texture more delicate and smoother. Additionally, the volatile components of soymilk before and after fermentation were analyzed by headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-ion mobility spectrometry (GC-IMS). It was found that the concentration of hexanal, which primarily contributed to beany flavor, gradually decreased with fermentation time, and so did the concentration of 1-octen-3-ol. The concentrations of diacetyl, acetoin and 2-heptanone and other flavor substances associated with fruity aroma gradually increased, thereby resulting in good flavor of soymilk. Furthermore, fermented soymilk with L. salivarius M18-6 had potent hydroxyl radical scavenging activity in a Caco-2 cell model of oxidative injury induced by acrylamide. Compared with the oxidative damage model group, the activities of catalase (CAT) and superoxide dismutase (SOD) in Caco-2 cells treated with the fermented soymilk increased by 2.67 and 30.80 times, respectively, and the concentration of glutathione increased by 13.83 times. In summary, soymilk fermented by L. salivarius M18-6 has a significant repairing effect on oxidatively damaged cells.
