摘    要:试验采用不同浓度的壳聚糖处理晚红葡萄.结果表明:在常温下贮藏至第10天时,用3%壳聚糖处理葡萄可以减少葡萄果梗的失水萎蔫,用3%的壳聚糖处理的晚红葡萄比对照的失水率降低62.14%.对其耐压力也有影响,用2%的壳聚糖处理的晚红葡萄比对照的耐压力高2.8倍,同时还抑制了PPO、POD酶的活性.

关 键 词:葡萄  壳聚糖  贮藏保鲜

Abstract:The effects of chitosan treatment on postharvest quality of grape(cv.Wanhong) were studies.Results showed that weight loss of grape fruit was reduced by 3% chitosan treatment during 10 d storage at room temperature.The weight loss in chitosan-treated fruit was 62.14% lower than that in control.In addition,chitosan treatment delayed the decrease in firmness and inhibited the PPO and POD activities of grape fruit.The firmness in treated fruit was 2.8-fold that in control.
Keywords:Grape  Chitosan  Postharvest
