Abstract: The microbiological and chemical compositions were studied during dry fermentation and ripening of sausage which fermented by Lactobacillus casei and Pediococcus pentosaceus,and the natural fermented sausages and the ones added with bacteriostatic agent were compared.The results showed that Lactobacillus casei and Pediococcus pentosaceus can marked increase the total number of living bacteria,effectively restraint maleficent bacteria,rapidly decrease the pH and AW value,significantly reduce the nitrite remnant allowance,and give the fermented sausages better security guarantee;In the function of inhibiting maleficent bacteria and decreasing the pH and AW value,Lactobacillus casei is stronger than Pediococcus pentosaceus,and is more suitable for the requirement of the fermented sausage security.

Key words: Lactobacillus casei, Pediococcus pentosaceus, fermented sausage, microbial change, physico-chemical and biochemical change
