摘要
以樱桃番茄(Lycopersicum esculentum var.cerasiforme)千禧作为试验材料,在低温条件下采用不同浓度的壳聚糖醋酸溶液(pH 5.5~5.8)对其进行涂膜处理,测定其总糖、维生素C含量、硬度和腐烂率的变化。结果表明,壳聚糖涂膜处理能明显降低其腐烂率,延缓果实硬度、总糖含量和维生素C含量的下降,质量分数1.5%的壳聚糖醋酸溶液涂膜处理保鲜效果较好。
Different concentrations of chitosan coating(pH 5.5~5.8) was used to treat cherry tomato(Lycopersicum esculentum var.cerasiforme) under low temperature to study its preservation effect.The changes of contents of total sugar,vitamin C,hardness and rot rate of cherry tomato were determined.The results showed that rot of cherry tomato was obviously delayed by chitosan coating,while the decreasing of fruit hardness,total sugar and vitamin C,and 1.5%(m/m) chitosan coating was also postponed,indicating its great efficiency in cherry tomato’s fresh-keeping
