摘　　要：以采后红地球葡萄果实为材料,用不同浓度的壳聚糖涂膜处理后低温贮藏,研究壳聚糖处理对低温贮藏下红地球葡萄果实保鲜效果的影响。结果表明,用壳聚糖涂膜处理能够降低红地球葡萄果实的失重率,延缓葡萄果实中的Vc含量、还原糖含量、可滴定酸含量及POD活性和SOD活性的降低速度,其中以1.5%的壳聚糖保鲜效果最好。This study was carried out to investigate the effect of different concentrations of chitosan coating on preservation of postharvest Red Globe fruit stored under low temperature. Results showed that chitosan coating treatment could reduced the berrys＇ weight loss rate, delayed the descent speed of Vc, sugar and titratable acid content, and POD and SOD activities. However, the suitable chitosan content was 1.5%.
