Abstract: In this study,the preservation effects of compound coating antistaling agent of locust bean gum on litchi at room temperature (30.5 ℃) were investigated. The antistaling agent was composed of locust bean gum with xanthan gum for the coating matrix,CMC-Na,citric acid and Tween 80 as film-forming additives,and the Chinese medicinal herb preparation such as clove,Artemisia leaf and rhubarb. The results showed that compared with the control group at room temperature,the rotting rate and weight lost rates of the litchi preserved by the compound coating antistaling agent are lowed obviously,the respiration rate,PPO activity and consumption of nutrient content are inhibited,and the senescence process is suspended during storage.

Key words: locust bean gum, compound coating antistaling agent, litchi, preservation, room temperature
