摘要
本文研究速冻草莓在-12、-18、-40℃三种温度下十四周贮藏中可溶性多酚氧化酶(PolyphenolOxidase,简称PPO)、过氧化物酶(Peroxidase,简称POD)及维生素C的变化,结果表明:不同温度下冻藏的草莓维生素C含量均呈下降趋势;冻藏初期可溶性多酚氧化酶、过氧化物酶活性上升,后期显著下降。
The changes of soluble polyphenol oxidase (PPO), peroxidase (POD) and vitamin C content of frozen strawberry in fourteen weeks' storage were studied at storage temperatures of- 12,- 18and-40 ℃. The results indicate that the content of vitamin C is showing a tendency to decrease, soluble polyphenol oxidase (PPO) and peroxidase (POD) activities increase at the early stage and significantly decrease late.
