Study on Dynamic Changes of Physiological Parameters and Storage Effects during Watermelon Preservation

Abstract

Abstract: The article studies the relationship between the active dynamic changes of polyphenol oxidase and hydrogen- peroxidase during watermelon storage about the changes of respiration intensity, firmness and cell membrane permeation rate so as to seek for a method to preserve watermelon better and the relationship among them. When the activity of polyphenol oxidase reaches the maximum, watermelon arrives at peak of breath. The active dynamic changes of polyphenol oxidase can indicate the arrival of the high breath peak. However it turns out that during the preservation the changes of respiration intensity of watermelon and the active changes of the hydrogen-peroxidase reverse relationship.

Key words: watermelon, polyphenol oxidase, hydrogen-peroxide, respiration intensity, firmness, cell membrane permeater ate
