To extend the shelf life of pitaya at room temperature (25 ± 1 °C), study the preservation of fresh pitaya packed by a multi-functional integrated bag, the AP bag, which is prepared by the intelligent hydrogel antiseptic film and the high permeability silicon window film. Compared with the experimental group, a set of parameters of the naked put in the control group have been measured, such as top air of bags, body composition, hardness of pitaya, total soluble solid content, total acid, and vitamin C content. At room temperature, the shelf life of pitaya naked put was just 6 days, and pitaya’s shelf life could be extended by 4 days with the AP bags, and it could keep the overall appearance of pitaya better. Since the gas permeation rate of the AP Bags is high, it can prevent pitaya from browning effectively and slow down the firmness reduction, and the micro-atmosphere effect inhibits the respiration of the fruit effectively. AP could effectively reduce the decrease of hardness and the water loss, and at the same time, the total soluble solid content and the total acid of AP were higher than the control group.
