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。
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% chitosantreatment 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.
