Abstract: The effect of preserving the fresh tilapia fillet by the high concentration ozone ice was studied in that assay. The results showed that the shelf-life could be lengthened 3~4 days preserved by 5mg/kg ozone ice, and the total volatility basis nitrogen (TVBN) was degreed and the bacteria colony was decrease to 82%~97%. The bactericidal effectiveness of ozone ice is strong enough to attain the better preservation effect. Being a convenient, simple, environmental friendly method, it could be adopted in the preservation and transportation of seafood. The passive situation of utilization of ozone in preservation was broken, a new effective procedure was setup for the aquatic product preservation.
