Grass carp slices was treated with ultraviolet,ozone and citric acid,and then stored at controlled freezing-point temperature(-0.7 ℃).During storage,the effects of different treatments on the aerobic bacterial counts,total volatile basic nitrogen value(TVB-N),2-thiobarbituric acid(TBA) value,pH value,total acidity and the sensory quality of grass carp were studied to provide data for the processing and storage of grass carp slices.The results showed that all three treatments inhibited microbial growth and d...
