摘　　要：目的研究淀粉复合膜包装贮藏樱桃过程中,复合膜扎孔对樱桃保鲜的影响。方法以"美早"樱桃果实为实验材料,采用淀粉复合膜密封聚丙烯硬质塑料盒包装樱桃,研究贮藏期间复合膜不扎孔、扎5孔、扎10孔、扎15孔、扎30孔等时对冷藏樱桃果实主要品质指标的影响。结果在樱桃果实贮藏20 d内,无孔包装与微孔包装樱桃果实品质无显著性差异(p>0.05);贮藏20天后,扎10孔和15孔包装的樱桃果实品质下降速度显著(p<0.05),低于其他微孔包装;在贮藏40 d后,扎10孔包装可以显著(p<0.05)延缓樱桃果实好果率、可溶性固形物、Vc含量、硬度等指标的下降。结论对保持樱桃果实在贮藏期间的品质而言,选用扎10孔或15孔的淀粉复合膜包装,在(0±0.5)℃,相对湿度90%~93%,不使用任何其它保鲜措施的情况下,可使樱桃贮藏期延长到60 d以上,好果率最高可达到85.9%。The work aims to study the effect of perforation in starch-based composite film on cherry preservation during storage period. Fresh ＂Meizao＂ cherries were selected as experimental materials, and then put into hard polypropylene plastic box sealed with starch-based composite films. One of the experimental groups was non-perforated, while other experimental groups were respectively perforated in order to obtain 5, 10, 15 and 30 holes during storage. The effect of such non-perforation and perforation on the main quality indicators for cherries under cold storage was studied. As a result, there was no significant difference in the quality of cherries with the non-perforated and micro-perforated packages during 20 days（p0.05） for cherry fruit preservation. The 10 holes and 15 holes of the packages could significantly reduce the rate of decay of the cherry fruit（p0.05） after storage for 20 days, lower than other micro-perforated packages. The decline of the good fruit rate, total soluble solid content, Vc content, firmness and other indicators was delayed remarkably when cherries were preserved by micro-perforated package with 10 holes（p0.05） after storage for 40 days. For the preservation quality during the storage, the cherry fruit packaged with starch-based composite films in 10 holes or 15 holes without any other preservation measures enabled the storage period of cherries to be extended to over 60 days and the highest good fruit rate to be 85.9% under the conditions of（0±0.5） ℃ and relative humidity of 90%～93%.
