摘要:

研究强酸电解水、弱酸电解水、臭氧水、次氯酸钠溶液和去离子水对新鲜草莓中微生物的杀灭效果,检测草莓清洗液中菌落总数等变化。结果表明:强酸电解水、弱酸电解水、臭氧水和次氯酸钠溶液清洗10min,草莓菌落杀菌率均达90%以上,清洗15min后杀菌率最高达到94.8%。其中,强酸电解水、弱酸电解水的微生物清除效果与次氯酸钠溶液相当,而其初始有效氯质量浓度仅为次氯酸钠溶液的一半。清洗草莓后的强酸电解水、弱酸电解水、次氯酸钠溶液中无存活菌落,臭氧水与去离子水中仍有菌落存在,且随清洗时间延长水中菌落数有所增加。

Abstract:

The bactericidal activity of strongly acidic electrolyzed water, slightly acidic electrolyzed water, ozonated water,
sodium hypochlorite and deionized water against microorganisms in strawberries was evaluated by measuring total bacterial
counts in the rinsing solutions. A bactericidal efficiency over 90% was achieved by rinsing in each sample for 10 min,
reaching the maximum of 94.8% when the rinsing time was 15 min. Strongly acidic electrolyzed water and slightly acidic
electrolyzed water had similar bactericidal activity to sodium hypochlorite, though their initial active chlorine concentrations
were only half that of sodium hypochlorite. No viable colonies were detected after strawberries were rinsed in strongly
acidic electrolyzed water, slightly acidic electrolyzed water or sodium hypochlorite, while more colonies in ozonated water
or deionized water were detected with increased rinsing time.

Key words: strongly acidic electrolyzed water, slightly acidic electrolyzed water, ozonated water, sodium hypochlorite, strawberry, bactericidal efficacy
