摘　　要：在制糖过程中,蔗汁中微生物活动是影响白糖产品品质的一个重要因素。为了消除糖厂有害菌对白糖产品品质的影响,本文主要探索了常用食品防腐剂、天然食品防腐剂、其它试剂以及氯化钠水溶液低压直流电解后对甘蔗压榨过程中危害最严重的明串珠菌类微生物的抑菌效果。实验结果表明,对羟基苯甲酸乙酯钠、注射用青霉素钠、乙二胺四乙酸钠(EDTA-2Na)均能有效抑制糖厂生产中主要的有害菌,其最低有效抑菌浓度分别为0.0016、0.0096、0.0056 g/L;氯化钠水溶液在20 V直流电压电解的抑菌效果与盐浓度的大小以及延迟时间相关,7%左右的盐溶液配合低压电解的抑菌作用最显著。In the process of sugar production, the damaging the quality of sugar products. In order to microbial activity in the cane juice is an important factor in inhibit the harmful effect of bacterium on the quality of sugar products, the antibacterial effect of common food preservatives, natural food preservatives, other reagents and sodium chloride aqueous electrolytes solution on Leuconostoc, the most harmful bacterium during the crushing process of cane sugar mills, was explored in this paper. The results showed that sodium p-hydroxybenzoate, ethyl injection of sodium penicillin, sodium ethylenediamine tetraacetate （EDTA-2Na） could inhibit the main harmful bacterium effectively during the process of sugar production and the lowest effective antibacterial concentration was 0.0016 g/L, 0.0096 g/L, 0.0056 g/L respectively. The antibacterial effect of sodium chloride aqueous electrolytes solution at 20 V is related to the salt concentration and the delay time, and the antibacterial effect of about 7% salt solution with low voltage electrolysis is the most significant.
