香菇低温贮藏中不同部位的生理生化变化
The Changes of the Physiology and Biochemistry at Different Sites in Shiitake Mushrooms (Lentinula edodes) Stored at Low Tempreture
摘要
Abstract
The aim of this study was to research the changes of the physiology and biochemistry at different sites in shiitake mushrooms stored at low temperature (4℃). The results showed the SOD and CAT activity and the VC content in pileus and upper part of stipe were higher than those in epidermis and lower half of stipe. The increasing rate of reducing sugar, the content of O2-, H2O2 and MDA in pileus and upper part of stipe were lower than those in epidermis and lower half of stipe. The total phenolic content in pileus was the highest. The PPO activity in epidermis was the highest while the PPO activity in pileus and upper part of stipe were lower. There was a sharp increase (P<0.01) of PAL activity in epidermis at 7 d, and the PAL activity in pileus was the highest in the early 7 d. These suggested that the pileus and upper part of stipe were of stronger capacities of antioxidation, anti-aging and anti-browning than that of epidermis and lower half of stipe.关键词
