摘  要:
以0℃冷藏为对照,采用 0℃、CO2>40ml/L和0℃、CO2<40ml/L贮藏条件处理富士苹果,并对贮藏中果肉褐变指数、保护酶活性、膜质过氧化水平进行测定。结果表明: CO2>40ml/L贮藏条件导致果肉褐变,在150d的贮藏过程中,褐变果实果肉中的超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性均呈下降趋势,丙二醛(MDA)水平则显著升高。

摘  要:
Fuji”apples were treated with 0℃、CO2>40ml/L and 0℃、CO2<40ml/L respectively with 0℃ storageas control test. The browning index and activities of SOD, POD and CAT, MDA level of the flesh tissue were investigatedrespectively. The results showed that CO2>40ml/L could induce flesh browning. Activities of SOD, POD and CAT decreasednotably and MDA level and relative electrical conductivity increased sharply in the browning fruits during storage.
