摘要
分离和纯化了导致大咯馇腐败的主要微生物,并作为优选天然复合保鲜剂的供试菌。对大咯馇的初始菌相进行了分析比较,确定各种腐败菌的分离率为:细菌为96.83%,霉菌为3.16%,初步分离优势腐败细菌1株,并用最大浓度保鲜液对优势腐败菌在平板上进行了抑菌性试验,抑菌圈为3.70cm,效果显著。对保鲜剂的单一成分及浓度进行正交试验,筛选出复合保鲜剂的最佳配比为T1,T2,T3的质量分数分别为5.0%,0.4%,1.0%。
The main bacteria causing the spoilage of Da gezha are isolated and purified.The initial proportion of bacteria of dagezha are compared.The proportions of these bacteria in the initial counts are bacteria 96.83% and mold 3.16% and the dominant bacteria in the initial count is bacteria a.The result of antibacterial properties of preservative TX on bacteria a is 3.70 cm of antibacterial zone.The results of orthogonal test are summarized as follows：the best ratio of compound preservative is 5.0%T1：0.4%T2：1.0%T3.
