A Preliminary Study on the Inhibitory Effect of Ozone on Shrimps Polyphenol Oxidase (PPO)

Abstract: Shrimps melanosis is caused by the formation of melanin as result of a series of biochemical reactions of tyrosine or its derivatives, such as water-soluble chromosome substances under the action of polyphenol oxidase (PPO). This article takes shrimps of East sea as testing object for studying and comparing the impacts of different ozone concentrations and […]
