Abstract

Abstract: In order to study on effect of different treat of LED composite light on preservation of broccoli, fresh broccoli was used as the main materials.By measuring the indicators at 4 ℃ low temperature conditions, such as sensory quality, vitamin C content, chlorophyll content and broccoli ethylene production rate, effect of LED composite light on preservation for broccoli was determined.The results showed that treatment with LED composite of red and blue was better for the quality of broccoli compared with non-light treatment.The former could extend storage time by 10-15 d.Meanwhile, it could got a higher score of sensory evaluation, prevented the rapid decline in important nutrient substance vitamin C content of broccoli, delayed the time of the evolution of ethylene and the appearance of respiration peak, decreased the respiration variable peak, and reduced membrane lipid peroxidation damage of broccoli during storage.

Key words: LED composite light, Broccoli, Storage, Quality control
