Effect of Chitosan Coating on Physiological and Quality Changes in Typha latifolia L.

Abstract

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.
