摘　　要：为了寻求牛奶连续接种的最佳工艺,采用中心组合设计研究了牛奶连续接种各参数的不同组合对牛奶连续接种稀释率的影响,建立各参数与牛奶连续接种稀释率之间的回归模型,考查了各参数间的互作效应。获得了牛奶连续接种的最优参数组合为:连续接种温度40.9℃、pH6.8、长径比4.8。In order to obtain optimum conditions for the continuous inoculation of milk with microcapsule Streptococcus thermophilus,the influences of different condition combinations on the dilution rate of milk continuous inoculation were studied by using central composite design,and the regression model on the dilution rate of continuous inoculation was established.The results suggested that the best conditions for the continuous inoculation of milk with microcapsule Streptococcus thermophilus were continuous inocu...
