Abstract:

In order to achieve the optimal ozone sterilization processing, grass carp was used as the raw material to explore the effects of ozone concentration, ozone treatment temperature and ozone treatment time on the quality of grass carp slices through evaluating water content, water-soluble protein content, free amino acid content, total sugar content, crude fat content, color, sensory evaluation and microorganism lethal rate. Results indicated that the optimal ozone treatment processing conditions were 0.85 mg/L ozone at 10 ℃ for 10 min treatment. Under the optimal ozone treatment processing conditions, the contents of water, water-soluble proteins, free amino acids, total sugar and crude fat, the degree of whiteness, sensory evaluation score and microorganism lethal rate were 79.55%, 155.67 mg/g, 0.63 mg/g, 8.23 mg/g, 6.34%, 48.12, 8.99 and 98.33%, respectively.

Key words: ozone, grass carp slices, quality
