摘要: 以生姜提取物为主要原料,研制一种对樱桃番茄保鲜效果显著的生姜复合抗氧化剂。在常温(20℃)条件下分别以不同的生姜复合抗氧化剂对樱桃番茄进行涂膜保鲜处理,以常温对照组作对比。测定了在贮藏过程中(0~12d)樱桃番茄的感官指标、总酸含量、总糖含量、可溶性蛋白含量、VC含量的变化及失重率、硬度等理化性能指标。结果表明:生姜复合抗氧化剂能减少樱桃番茄水分的散失,降低霉变率,维持较高的营养成分。保鲜效果最好的生姜复合抗氧化剂的组成及配比为:生姜提取物+抗坏血酸+柠檬酸(3:1.5:0.5)。

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).
