Fermentation characteristics of low-temperature fermented venison product were studied. Venison and pork were chosen as raw materials. Lactobacillus plantarum (Lp) , Bifidobacterium(Bb), lactic acid Streptococcus(St) and dry yeast (Bs) were starters in the fermented venison product. Changes of water content, pH value, volatile basic nitrogen,sodium nitrite content, amino acid content and POV during the fermentation were investigated by four-factor three-level orthogonal experiment. Optimal procession parameters were as follows: total inoculation of Bs and St was 0.3% , Bs: St=1: 1 ,inoculation of Lp was 0.5×107, temperature during the fermentation was 25℃, and fermenta-tion duration was 24 h. Optimal proportions of primary materials were:pork to venison ratio 6:4, pig fat 10%, potato starch 9%, and glucose 8%.
