摘要：
The aim of this research is to investigate the effect of lactic acid bacteria(LAB) on color stability of fresh pork. Of the seven LAB strains isolated from the Chinese dry-cured hams, H strain was identified as Lactobacillus salivarius(CCTCC M2010374) by serial biochemical tests and16 S rRNA analysis. The fresh pork samples were immersed in the H strain and Lactobacillus fermentum extracts for 1 min after ultrasonic cells disruption and samples immersed in sterile 0.9%(m/V) saline was served as a control group, then samples were vacuum packaged and stored at4℃. Nitrate oxide synthase(NOS) and metmyoglobin(Met Mb) reductase were found in the cells extracts of H strain. After 6 days of storage, H strain group was found to be associated with the highest CIE a~* values(P < 0.05) and the lowest Met Mb(41%). L. salivarius H strain has thus shown a beneficial effect on the color stability of fresh pork. Further research is necessary to elucidate its mechanism.
