    摘要:

    分别以浓度0.00%,0.25%,0.50%,0.75%的水溶性蜂胶与1.50%的壳聚糖、1.00%的氯化钙配制复合涂膜剂,对鲜切苹果进行涂膜处理,检测鲜切苹果在不同时期失重率、褐变度、可滴定酸含量、抗坏血酸含量和硬度等指标,以探究蜂胶对鲜切苹果的保鲜效果。结果表明:加入0.50%水溶性蜂胶的鲜切苹果处理组对硬度和可滴定酸有较好的保鲜效果,加入0.75%水溶性蜂胶的处理组对失重率、褐变度和抗坏血酸含量有较好的保鲜效果,而涂膜剂中加入水溶性蜂胶对鲜切苹果的菌落总数有一定负面影响。涂膜剂中加入适量的水溶性蜂胶对鲜切苹果短期内的贮藏品质保持有促进作用。

    Abstract:

    In order to study the effect of propolis compound coating agent on fresh-cut apple. The compound coating agent was prepared with 0.00%, 0.25%, 0.50% and 0.75% water-soluble propolis, 150% chitosan and 1.00% calcium chloride to coat the fresh-cut apple. The weight loss rate, browning degree, titrate acid contents, ascorbic acid content and hardness of fresh-cut apples in different periods were detected to investigate the effect of propolis to fresh-cut apple. The physical and chemical indexes of fresh-cut apple in different storage periods were compared and analyzed. The coating agent with 0.50% water-soluble propolis was added to the hardness and titratable acid of fresh-cut apple. The coating agent with 0.75% water-soluble propolis had better effect on weight loss rate, browning degree and ascorbic acid content of fresh-cut apple, while the coating agent with water-soluble propolis had some negative effects on the total colony of fresh-cut apple. To sum up, adding proper amount of water-soluble propolis in the coating agent could improve the quality of fresh-cut apple in short term.
