| 目的 探讨魔芋葡甘露聚糖/纳米ZnO复合涂膜对常温贮藏香蕉保鲜效果的影响，为香蕉的采后常温保鲜贮藏提供新途径。方法 以巴西蕉为实验材料，采用KGM涂膜液（A组）和KGM/纳米ZnO复合涂膜液（B组）等2种可食性涂膜液对香蕉进行涂膜处理，以不做任何处理为对照（CK组），置于夏季常温(32±2)℃下贮藏，每天取样测定果实的好果率、褐变指数、质量损失率、可溶性固形物含量、Vc含量等指标。结果 在整个贮藏期间，与KGM涂膜和对照组相比，KGM/纳米ZnO复合膜能显著维持香蕉的好果率，抑制香蕉的褐变，降低香蕉在贮藏期的质量损失率，减少可溶性固形物和维生素C等营养物质的损失。结论 KGM/纳米ZnO复合涂膜液对采后香蕉的常温贮藏效果最好，能够维持香蕉较好的贮藏品质。 |

| The work aims to study the effects of konjac glucomannan/nano-ZnO composite coating on banana preser-vation at room temperature, in order to provide a new way for post-harvest storage of bananas at room temperature. With Brazil bananas as experimental material, two edible coating solutions like KGM hydrosol (group A) and KGM/nano-ZnO composite hydrosol (group B) were used for coating treatment of bananas, and the non-treated bananas were considered as control (group CK). Both treated and non-treated bananas were stored at room temperature of (32±2)℃ in summer. Sampling was done every day to measure the banana's good fruit rate, browning index, weight loss rate, soluble solids content, Vc content and other indexes. The results showed that, in the whole storage period, compared with KGM coating and control group, KGM/nano-ZnO composite coating could significantly maintain the good fruit rate, inhibit the browning, reduce the weight loss rate in the storage period and decrease the loss of nutrients such as soluble solids and vitamin C of banana. The KGM/nano-ZnO composite coating solution has the best effect on the storage of post-harvest bananas at room temperature, which can maintain its high storage quality. |
