This study investigated the effects of salt (3% and 6% w/w) and rice flour (10% and 20% w/w) addition in sour meat， a traditional Chinese fermented meat. It was found that salt has greater effect than rice flour addition in spontaneous fermentation. Low-salt groups had lower pH and higher titratable total acid. In the low-salt groups， the dominant genera were Lactobacillus and Lactococcus， whereas Staphylococcus， Weissella， and Tetragenococcus were dominant in the high-salt groups. Higher total free amino acids and essential amino acids， organic acids， hexanoic acid ethyl ester and octanoic acid ethyl ester were found in the low-salt groups. The RDA analysis revealed that Lactococcus was closely related to product quality， with the S3F10 (3% salt and 10% rice flour) group outperforming the others in the sensory evaluation. Therefore， 3% salt and 10% rice flour were considered more appropriate for the production of healthy and tasty fermented sour meats.
