臭氧水对军曹鱼片的减菌效果和品质的影响

Sterilization and quality effects of ozone water on cobia fillets

摘要: 文章研究比较了不同质量浓度的臭氧水处理军曹鱼(Rachycentron canadum)鱼片对其减菌效果和品质的影响。在15 ℃条件下分别以质量浓度为4 mg·L^-1、5 mg·L^-1、6 mg·L^-1和7 mg·L^-1的流动臭氧水处理军曹鱼片，以减菌率、感官和色泽为评价指标。结果表明，质量浓度为7 mg·L^-1的流动臭氧水处理军曹鱼片10 min可以达到一个较好的减菌效果，减菌率达到81.12%，且该臭氧水质量浓度对军曹鱼的品质影响较小。

Abstract: In order to study the sterilization and quality effects of ozone water on cobia fillets, flowing ozone water at various concentrations of 4 mg·L^-1, 5 mg·L^-1, 6 mg·L^-1 and 7 mg·L^-1 was experimented to screen the optimal condition at 15 ℃. Comparing the effects of sterilization ratio, sensory evaluation and color difference in different groups, we find that the treatment with 7 mg·L^-1 flowing ozone water for 10 min on cobia fillets gets a better sterilization ratio of 81.12% without reducing the quality.
