Sterilization and quality effects of ozone water on cobia fillets

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.
