| 目的 研究ε-聚赖氨酸盐酸盐/壳聚糖复合涂膜对樱桃的保鲜效果。方法 以“美早”樱桃为保鲜对象，采用壳聚糖涂膜、ε-聚赖氨酸盐酸盐/壳聚糖复合涂膜保鲜樱桃，以未涂膜处理的樱桃为空白对照，并用一次性打孔水果包装盒包装樱桃，研究冷藏贮藏期间不同处理组樱桃的主要品质指标随贮藏时间的变化情况。结果 ε-聚赖氨酸盐酸盐/壳聚糖复合涂膜在降低樱桃质量损失率、凹陷率、腐烂率等方面表现更佳；在贮藏6 d后，ε-聚赖氨酸盐酸盐/壳聚糖复合涂膜处理组樱桃的可滴定酸质量分数为0.52%，Vc含量为59.5 mg/kg，与未涂膜的空白组樱桃相比，可以在一定程度上减缓樱桃中可滴定酸和Vc含量的降低；ε-聚赖氨酸盐酸盐/壳聚糖复合涂膜能够更好地改善贮藏期间樱桃的硬度和色泽。结论 ε-聚赖氨酸盐酸盐可以与壳聚糖协同作用，对樱桃发挥更好的保鲜作用。 |

| The work aims to study the effects of ε-polylysine hydrochloride/chitosan composite film on the preservation of cherries.The cherries were coated with chitosan film and ε-polylysine hydrochloride/chitosan composite film for preservation, respectively, and the uncoated cherries were used as blank control group.Then, the cherries were packaged in disposableperforated fruit box.The changes in main quality factors of the cherries in different groups were studied during cold storage.ε-polylysine hydrochloride/chitosan composite filmshowed the best effects inreducing the weight loss rate, sag rate and rot rate of cherries. After 6 days of storage, the content of titratable acid of the cherry treated with ε-polylysine hydrochloride/chitosan composite film was 0.52%, and the Vc content was 5.95 mg/kg.Compared with the uncoated cherries, the decrease of titratable acid and Vc content in coated cherries was slowed down.ε-polylysine hydrochloride/chitosan composite filmcouldalso improve cherry hardness and color during storage.ε-polylysine hydrochloride can work with chitosan to play a better role in keepingthequalityofcherries. |
