Abstract Effect of environment factors,such as salt concentration,water activity,temperature and time of fermentation,sugar concentration on total bacteria count,lactic acid bacteria and micrococcus was studied with response surface experiment design of SAS software.Scientific mathematical models were founded.Optimization the process conditions of traditional fermented sausage,it can be found that the best technology was salt concentration 5%,Aw 0.95,fermentation temperature 14℃,fermentation time 20d,sugar concentration 2%.The sensory evaluation between the optimum conditions to produce fermented sausage products and the traditional process for the production of sausage products,new technology products fermented for 20 days compared with the traditional process of fermentation products with 30 days, the result represented the sensory evaluation was no significant difference,the new technology was feasible.Applied the mathematical model to predict the number of microorganism during fermentation, the result was credible.It gave some information to regulate fermentation,provided safetyof fermented sausage products and shortened production cycle,and also was an important elements of prediction microbiology.
