    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.
