“…Besides, the SAA content in the D group was >5 times that in the G group, and showed an upward trend with the extension of fermentation time. The possible reason for the result might lie in the fact that in the fermentation process, suitable temperature and lower salt concentration made protease activity higher, which degraded proteins in pickled peppers into amino acids ( Chen et al, 2024 ). As the fermentation progressed, the content of UAA in the D group gradually decreased, while that in the G group generally showed a gradual upward trend and slightly decreased at 90 d of fermentation.…”
