Abstract:
With strawberry as materials，the fresh-keeping effect of compound paintfilm liquid of chitosan and extraction from ginger and garlic with different matching on fruits at room temperature was studied by using 8 kinds of paintfilm liquids included chitosn at 0.5%～2.0% with or without extraction from ginger and garlic.The results showed that rot index after 4 days in treatment 7 (1.5% chitosan with extraction from ginger and garlic) was lowest，being 1.110.The depression effects on fruitweight loss rate during storage by T3(1.5% chitosan without extraction from ginger and garlic),and T7 and T8 (1.5% and 2.0% chitosan with extraction from ginger and garlic)were more obvious，with the fruit weight loss rate being 9.02%,6.94% and 7.74% resp.T7 had littlest effect on fruit total acid content and VC content.Painting fruits with T7 compound paintfilm liquid had best fresh-keeping effect.It restrained increment of fruit rot index and weight loss rate significantly，delayed decrement of fruit total acid and VC contents and its effect was obviously better than with other treatments.
