WANG Lei(Harbin Commercial University, Harbin, 150028, China)
The tomatoes' physical properties and post harvest physiological status were analyzed combined with ozone freshkeeping mechanism and characteristics. The tomatoes' ozone freshkeeping technical method was studied and the changes of tomatoes' outside sense, water, VC content, starch, deoxidized sugar, total acid, rotten rate, rigidity, soluble solid content,etc. were analyzed. It was proved by experiments that tomatoes' freshness, sense, taste did not changed by applying ozone freshkeeping packaging technology under normal temperature, the tomatoes' quality were excellent and this method can prolong the freshkeeping period more than 14 days.
