The results showed that increasing salt concentration could significantly decrease T21 moisture proportion and relaxation time (p less then 0.05), which was more beneficial to the lipase activity. The TG hydrolase activity increased first and then decreased with the salt concentration increasing during dry-salting process, and 3% salt concentration was the point of inflection. Western blot (WB) analysis detected both ATGL, HSL and their phosphorylated proteins, which were increased with the salt content increase. The microstructure analysis showed that the lipid droplets were split into small lipid droplets with the increase of salt content, which was more conducive to the triglycerides hydrolysis.In this study, a high-throughput strategy combined with MALDI TOF/TOF-MS and Discovery Studio 2017 was developed to screen peptides with certain functions from hydrolysate. Two dominant peptides, Ile-Cys-Arg-Asp (ICRD) and Leu-Cys-Gly-Glu-Cys (LCGEC), were predicted to have antioxidant activity by Discovery Studio 2017. Then the activity in vitro of peptides had been confirmed via DPPH assay. Both two peptides decreased apoptosis induced by UVB treatment in HaCaT cells and altered Keap1/Nrf2-ARE pathway transcription. Furthermore, the antioxidant activity of LCGEC was achieved after 6-week treatment in mice via regulating the Keap1/Nrf2-ARE pathway, inhibiting the release of proinflammatory cytokines, increasing the abundance of 3-indolepropionic acid and short-chain fatty acids production in feces and modulating gut microbiota compo
