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 package and humidity, etc. of apples in two kinds of corrugated cartons were compared under the room temperature and constant 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.
