摘要: 本实验以长角豆胶与黄原胶复配胶为涂膜基质,CMC-Na、柠檬酸和吐温80等为成膜助剂,配以丁香、艾叶和大黄等具有抗菌作用的中草药制剂,配制成中草药复合涂膜保鲜剂,研究了常温(均温30.50℃)下该复合涂膜保鲜剂对荔枝品质变化的影响。结果表明:常温下经该保鲜剂涂膜保鲜的荔枝与对照组相比,果实腐烂率、失重率明显降低,呼吸强度、PPO活性及营养成分的消耗被抑制,延缓了果实的衰老过程。

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
