Abstract:In order to further clarify the inhibitory effect of microbial nitrosation inhibitors (MNI) on the production of N-nitrosamines in sauced beef, the sensory evaluation, pH, thiobarbituric acid reactive substances (TBARs) value, nitrite, biogenic amine and N-nitrosamine contents of sauced beef treated with LS-MNI from Lactobacillus sake (LS) or WBL-45-MNI from commercial starter culture WBL-45 (Staphylococcus xylosus + Staphylococcus carnosus + Lactobacillus sake) were measured. The results showed that adding LS-MNI or WBL-45-MNI to sauced beef significantly improved its color and flavor. The overall sensory score of the WBL-45-MNI group was significantly higher than that of the LS-MNI and control groups (P < 0.05). Furthermore, the nitrite residue and total biogenic amine content were significantly lower than those of LS-MNI and control groups (P < 0.05). None of TBARs values of the three groups exceeded 0.2 mg/kg. For the WBL-45-MNI and LS-MNI groups, the inhibition rates of NDMA were 70.94% and 89.74%, respectively, and the inhibition rates of total N-nitrosamine were 46.79% and 36.50%, respectively. The above results show that LS-MNI and WBL-45-MNI can block the formation of N-nitrosamines in meat products, the overall effect of WBL-45-MNI being more significant.
