壳聚糖精油生物涂膜剂对苹果保鲜效果的研究
Effect of Chitosan Oil Biological Coating Agent on Apple Preservation
摘要
Abstract
In this study, apples were stored under the conditions of relative humidity of 95% and 8℃, to investigate the effect of chitosan (1.5%), oil processing (0.25%) and chitosan (1.5%)+oil processing (0.25%) on the apple weight loss rate, titratable acid, polyphenol oxidase (PPO), total phenols, cell membrane permeability and the quality of sensory. Results indicated that, three treatments had inhibitory effect on apple. Especially, 1.5% chitosan + 0.25% essential oil treatment had the best effect. After 150 days storage, the color and texture of apples were all normal, and there were no rotten fruits. What's more, weight loss rate reached a value of 8%, titratable acid was 0.25%, the PPO was 13%, the total phenol was 26% and membrane permeability was 35%, which are all better than the control group, 1.5% chitosan treated group and 0.25%essential oil treated group.关键词
