摘  要：
对腌制蔬菜中的腐败菌进行分离与鉴定,结果表明:腌制蔬菜中腐败菌主要为6株细菌,其中4株球菌,1株链杆菌,1株杆菌,都为革兰氏阳性菌。对腐败菌的抑菌剂进行筛选与优化,结果表明:Nisin、脱氢醋酸钠、尼泊金复合酯钠对腐败菌有明显的抑制作用。正交试验优化得到复合防腐剂最佳配方为:Nisin0.4g/L、脱氢醋酸钠0.3g/L、尼泊金复合酯钠0.2g/L。在该复配条件下对于实验中分离得到的6种腐败菌及食品中常见的腐败菌(金黄色葡萄球菌和枯草芽孢杆菌)都有良好的抑制效果,抑制率都在96%以上。

摘  要：
Separation and identification of spoilage bacteria from pickled vegetables indicated that there were six dominant Grampositive bacteria including four strains of coccus,one strain of streptobacillus and one strain of bacillus.Meanwhile,the screening and optimization of bacteriostatic agents on spoilage bacteria were conducted.An obvious suppression effect of Nisin,sodium dehydroacetate or sodium Nipagin on spoilage bacteria was observed.Moreover,a compound preservative was optimized to be 0.4 g/L Nisin,0.3 g/L sodium dehydroacetate and 0.2 g/L sodium Nipagin ester through orthogonal test.This compound preservative exhibited an excellent suppression effect on six strains of bacteria separated from pickled vegetables and common spoilage bacteria such as Staphylococcus aureus and Bacillus subtilis in food.The suppression rate could reach up to 96%.
