Abstract:

Effects of different concentrations of NaCl on acidity and TVB-N of Qinchuan beef and effect of different lactic acid bacteria (Lacidophilus and S.thermophilns, at the ratio of 1:1) addition and different fermentation time on beef acidity, TVB-N and shear force in the fermentation process were investigated. The results showed that when the concentration of NaCl, lactic acid bacteria addition and fermentation time are 30 g/L, 2 to 3 g/L and 2 to3 h, respectively, the beef quality (TVB-N no more than 5.0 mg/100 g, shear force no more than 39.20N, acidity no more than 1.0g/kg) is the best. In conclusion, lactic acid fermentation may significantly (p < 0.01) improve the beef quality.

Key words: Qinchuan beef, lactic acid bacteria, fermentation, quality change
