To explore the effects of different irradiation doses treatments on the quality changes of Actinidia arguta during the shelf life after the end of cold storage.
In this study, Actinidia arguta were treated with different irradiation doses. By comparing the fruit’s appearance, decay rate, firmness, color, soluble solids content, titratable acid and total phenol content, the effects of different irradiation doses on the storage performance of Actinidia arguta during the shelf life after refrigerated storage were determined.
The 1.5 kGy irradiation treatment showed a significant effect in delaying the ripening and softening of Actinidia arguta and maintaining the comprehensive quality of the fruit. After 50 d of refrigerated storage, the fruit treated with this dose still had a shelf life of 8 d, maintained a firmness of 0.52 N, and had a decay rate controlled at 49.2%. The fruit color was also well preserved. In addition, the loss rate of flavor and nutrient substances inside the fruit was significantly reduced (P<0.05).
For Actinidia arguta, the 1.5 kGy irradiation treatment effectively inhibits softening caused by postharvest physiological ripening, controls the decay rate, and slows down the degradation of nutrients.Meanwhile, it ensures that the sensory and physiological quality of the fruit is not negatively affected. Thus, it is a feasible fresh-keeping method that can significantly improve the storage quality of Actinidia arguta and extend their shelf life after refrigerated storage.
