| 摘 要： | 在蒲菜贮藏过程中，通过评价其外观品质及测定其失重率、腐烂指数、维生素C含量、纤维素含量和多酚氧化酶活性等指标，研究壳聚糖涂膜对蒲菜采后生理和品质的影响。结果表明：蒲菜在采后前20d维生素C含量迅速下降，失重率和纤维素含量上升较快，10d后腐烂迅速增加，而多酚氧化酶活性呈“低－高－低”变化。壳聚糖涂膜能抑制蒲菜储藏期间的蒸腾失水和多酚氧化酶活性，保持较低的纤维素含量和较高的维生素C含量，从而延缓蒲菜的衰老与品质下降，延长储藏寿命，达到保鲜目的。 |

| Abstract: | In order to study the effect of chitosan coating on keeping fresh to Typha latifolia L., the sensory quality of T. latifolia L. as well as its rate of weight loss, decay index, Vitamin C content, fibrin content and polyphenol oxidase(PPO) activity, were determined after treated with chitosan coating. During its storage process, the content of Vitamin C decreased while the weight loss and the content of fibrin increased rapidly during the first 20 days of storage, followed by a rapid increment in decay index during the later days of storage, but the PPO activity changed with the rate of "low-high-low". Chitosan coating could inhibit the weight loss and the PPO activity, maintain lower levels of fibrin content but higher content of vitamin C, thereby delayed the senescence process and quality loss and prolonged storage life of T. latifolia L. |
