Abstract: To explore the effects of different light modes on the storage quality of cherry tomatoes during postharvest refrigeration, the four treatment modes of red and blue LED composite light were used to illuminate cherry tomatoes when they were stored in the refrigerator at 4 ℃, as follows: light for 10 min+no light for 50 min, light for 30 min+no light for 150 min, light for 4 h+no light for 20 h, and no light treatment were used as the control group. The effects of each treatment on the weight loss rate, color, vitamin C content, total phenol content, flavonoid content, and lycopene content of cherry tomatoes during cold storage were studied. The results showed that compared with the control group, the different LED lighting modes could slow down the loss of nutritional quality of cherry tomatoes during storage. The combination of light for 4 h+no light for 20 h had the most significant effect on maintaining the appearance of cherry tomatoes and delaying the degradation or increasing nutrient content during the refrigeration process. On the 8th day of refrigeration, the weight loss was only 2.72%. Compared with the control group, the vitamin C content, total phenol content, and flavonoid content were increased by 20.74%, 47.93%, and 43.59% on the 4th day, respectively, and the lycopene content was increased by 19.59% on the 6th day. This condition is suitable for combining with cold storage technology to maintain the quality of cherry tomatoes after harvest. This study provides an important reference for improving the quality of fruits and vegetables refrigerated after harvest by different treatment modes of red and blue light.
