摘要
以‘中白’品种的番木瓜为试验材料,研究壳聚糖涂膜处理对番木瓜在常温25℃条件下的保鲜效果。结果表明,壳聚糖涂膜处理有效减少水分散失,提高SOD酶活性,降低MDA的积累,维持果实硬度并延缓果实衰老进程,其中以1.0%的壳聚糖涂膜处理效果最好。
Papaya fruit collected from Papaya variety Zhongbai（ Carica papaya L.） were treated by coating with chitosan at three different concentrations and stored at a room temperature of 25 ℃ to observe their quality. The results showed that chitosan coating significantly reduced moisture loss,increased superoxide dimutase（ SOD）activity,and decreased the accumulation of malondialdehyde（ MDA） from papaya fruits. The fruit treated with chitosan coating showed better fruit firmness and a delayed senescence. Of all the treatments the fruits coated with a 10% concentration of chitosan were best fresh kept.
