Abstract:

The aim of the study is to explore the effect of storage temperature on the storage quality of passion fruit, and provide reference for improving the postharvest-storage quality of passion fruit. The passion fruit ‘Tainong No.1’ was used as experimental material. The mature fruits were stored at 4℃, 8℃ and room temperature, respectively. The quality indexes were measured every 2 days. The results showed that low temperature storage (4℃ and 8℃) could significantly delay the color change and the shrink of fruit, and maintain high sensory quality and prolong shelf life. There was no significant difference in total soluble solid (TSS), titratable acid (TA), TSS/TA and sensory quality of fruits (P>0.05). At the room-temperature storage, the TSS was significantly higher than that of low temperature storage from day 4 to day 6 (P<0.05), and significantly lower than that of low temperature storage at day 14 (P<0.05). The TA was significantly lower than that of low temperature storage after 10 days (P<0.05). The TSS/TA was significantly higher than that of low temperature storage after 6 days (P<0.05). The sensory quality was significantly higher than that of low temperature storage from day 2 to day 6 (P<0.05), and significantly lower than that of low temperature storage after 10 days (P<0.05). The weight loss rate of fruits increased with the extension of storage time and the increase of storage temperature. In conclusion, the fruit quality at room temperature storage is better than that of low temperature storage for the first 6 days, but low temperature storage could maintain high sensory quality and prolong shelf life.
