摘要
以长角豆胶、黄原胶为涂膜基质,添加具有抗菌作用的黄连、艾叶提取物,对番荔枝进行涂膜处理,于常温及8、12℃低温进行贮藏试验,研究黄连和艾叶复合涂膜保鲜剂结合低温对采后番荔枝感官品质和生理生化指标的影响。结果表明:涂膜保鲜结合低温贮藏,可有效保持番荔枝果实硬度,降低番荔枝采后裂果率、霉果率和褐变指数,抑制淀粉酶、PPO等活性,减缓可溶性固形物及淀粉转化速率。其中,复合涂膜结合8℃贮藏效果略优于12℃。低温条件下中药黄连和艾叶复合涂膜保鲜剂对延缓番荔枝果实衰老起到一定的促进效果。
In the paper,effects of the compound film-coating antistaling agent of Locust bean gum with xanthan gum on Annona squamosa Fruits quality at low temperature of 8℃,12℃ and room temperature were studied. The antistaling agent was composed of Locust bean gum with xanthan gum for the coating matrix,the antimicrobial Chinese medicinal herb such as Coptis chinensis and Artemisia argyi was taken as film-forming additives. The results showed that,compared with control group,cracking rate,bad fruit rate and browning index could be reduced,enzyme activitivity of amylase and PPO could be inhabited,the rate of soluble solids and starch transformation could be slowed down. The effect of composite film-coating at 8℃ of storage was slightly better than that preserved at 12℃. Under low temperature condition,the composite film-coating antistaling agent of Chinese medicine C. chinensis and A. argyi played a certain role in delaying the aging of A. squamosa.
