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

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.
