Abstract: Ginger composite antioxidants for preservation of cherry tomatoes were developed with ginger extract the main material. The ginger composite antioxidants of different formulas were used for coating preservation of cherry tomatoes at the ambient temperature (20 ℃),in comparison with ginger composite antioxidant film at ambient temperature. The indexes such as senseory index,total acid,contents of total sugar,soluble protein and vitamin C,weight losts rate and hardness were assayed during storage (0～12 d). The results indicated that during the storage period,ginger composite antioxidants could decrease the rotting rate,nutrient loss rate and weight loss rate and inhibit and delay the senescent course,and the best preservative formula is ginger extraction + ascorbic acid + citricacid (3:1.5:0.5,W/W/W).
