摘要:

本实验针对乳酸菌降低发酵烤肠亚硝酸盐残留量进行了研究,以发酵烤肠的亚硝酸盐的残留量、pH值为指标,并兼顾产品的品质。针对影响发酵烤肠的四个主要因素:发酵菌种(植物乳杆菌、嗜热乳链球菌:保加利亚乳杆菌=1:1混合菌、德国科汉森乳酸菌)、接种量、发酵温度和发酵时间进行了单因素试验;在确定较优工艺参数的基础上,以产品的亚硝酸盐残留量的降解率和感官评分为指标,进行了正交试验,最终确定最优化的工艺参数为:发酵菌种是德国科汉森复合乳酸菌,接种量为2.0%,发酵温度为30℃,发酵时间为22h。

Abstract:

With nitrite residue, pH value and sensory score as indexes, the effects of Lactobacillus fermentation conditions, such as Lactobacillus species (Lactobacillus plantarum, Streptococcus thermophilus plus Lactobacillus bulgaricus with the ratio of 1:1 and Germany Kehansen Lactobacillus), inoculation amount, fermentation temperature and fermentation time on quality of fermented roast sausages were investigated through single-factor test, and then these conditions were optimized to reduce  the nitrite residue and enhance the sensory score through orthogonal test. The results showed that the optimum fermentation process is as follows: fermenting sausage with 2.0% of Germany Kehansen Lactobacillus at 30 ℃ for 22 h.

Key words: fermentation, Lactobacillus, nitrite residue, fermented roast sausage
