臭氧水、电解水和高盐溶液对冷藏大黄鱼品质的影响

Effect of ozone water, electrolyzed water and high salt solution on the quality of large yellow croaker during the refrigerated storage

摘要: 以感官评价、细菌总数、TVB-N、K值、pH作为品质指标,比较了臭氧水（2.3mg/L）、电解水（ORP 500mV）和高盐溶液（10%NaCl）减菌处理对大黄鱼品质的影响。结果表明,臭氧水和电解水处理组具有显著抑制细菌总数和产H2S菌的增长,减缓TBA、TVB-N、K值上升的作用,臭氧水效果更佳,而高盐溶液处理组无显著作用。臭氧水处理可延长大黄鱼贮藏时间3⁶d,可以作为大黄鱼保鲜较好的减菌处理技术。

Abstract: Based on the sensory evaluation, total bacterial count (TVC) , total volatile basic nitrogen (TVB-N) , K value, pH, the influence of ozone water (2.3mg/L) , electrolyzed water (ORP 500mV) andhigh salt solution (10%NaCl) on the quality of large yellow croaker was studied comparatively. The results showed that treatment of ozone water and electrolytic water significantly inhibited the growth of the TVC and H2S producing bacteria, delayed the increase of 2-thiobarbituric acid (TBA) , TVB-N, K value, especially for the former one. Whereas, no significant changes of high salt solution was observed compared with control. The treatment of ozone water could extend the shelf life of large yellow croaker 3 ⁶ days, which could be used as a good technique of reduction bacteria in the preservation of large yellow croaker.
