【摘要】 研究了热空气处理和贮藏温度对水蜜桃硬度、果皮色泽、色素含量、呼吸作用、乙烯释放、脂肪氧合酶 (LOX)与过氧化物酶 (POD)活性的影响。结果表明 :4 0℃热空气处理 2 4小时可保持果实的硬度、抑制果皮中叶绿素的降解 ,推迟了呼吸高峰的出现 ,保持了细胞膜的完整性 ,热处理抑制了乙烯的释放 ,降低了LOX和POD活性。

【Abstract】 The effects of hot air treatment and storage temperature on firmness, soluble solids, pH, peel color, and respiration of peach, ethylene release and activity of LOX and POD were studied The results showed that the treatment with hot air at 40°C for 24h could maintain firmness, inhibit the degradation of chlorophyll in fruit peel, delay respiration summit, and maintain better cell membrane integrity. Hot air treatment could inhibit ethylene release, as well as decrease activity of LOX and POD
