Abstract
The processing technology and changes of physicochemical properties of fermented sausage were researched.Employing orthogonal experiment design,the optimal formula were that the ratio of Lactobacillus bulgaricus and Streptococcus thermophilus 1∶1,sugar 8% and salt 2.5%.The optimal technology was that starter cultures 1.5%,fermented temperature 42℃ and fermented time 12h.The changes of pH and color parameters of fermented sausage during fermentation and maturation initial stages were also studied.
