苹果快递运输中的保鲜瓦楞纸箱研究

Corrugated Carton for Apple Express Delivery

目的研究保鲜瓦楞纸箱对采后苹果的运输保鲜效果。方法对比2种保鲜瓦楞纸箱内的苹果在室温和恒温恒湿等2种环境下的质量损失率、坏果率、果实硬度、可溶性固形物含量,以及包装内部温度、湿度等各项品质理化参数的变化。结果在常温(10～18℃)和恒温恒湿(温度为26℃,相对湿度为73%)等2种贮藏条件下,A1组保鲜瓦楞纸箱内果品的品质和商业价值可以保持3 d,2种情况下的质量损失率分别为0.98%和1.37%,果实硬度保持在8.2 kg/cm^2和8.9 kg/cm^2,可溶性固形物质量分数分别为11.9%和14%,明显优于A2组。结论 A1组保鲜瓦楞纸箱能有效抑制采后苹果的呼吸作用,基本满足快递运输的需要。

The work aims to study the fresh-keeping effect of postharvest apples transported by corrugated carton. The change in weight loss rate, decay rate, fruit hardness, the content of soluble solids, internal temperature of the pack-age and humidity, etc. of apples in two kinds of corrugated cartons were compared under the room temperature and con-stant temperature and humidity. The results showed that the quality and commercial value of fruit could be maintained in group A1’s corrugated cartons for three days under two storage conditions： room temperature （10~18 ℃） and constant temperature and humidity （26 ℃, 73%）. Under the above-mentioned two conditions, the weight loss rates were 0.98% and 1.37%, respectively, and the fruit firmness was maintained at 8.2 kg/cm2 and 8.9 kg/cm2. The mass fraction of soluble solids was 11.9% and 14%, which was significantly better than that in group A2. The group A1’s corrugated cartons can effectively inhibit the respiration of postharvest apples, and basically meet the needs of express delivery.
