红桔浮皮枯水果生理生化指标的测定

:测定了红桔浮皮枯水果的生理生化指标 ,结果表明 :浮皮果的密度为 6 43.0～ 80 0 .0kg/m3,枯水果的密度低于 6 43.0kg/m3。与正常果比较 ,枯水果的总酸含量、果肉水分含量及出汁率明显下降 ,过氧化氢酶的活性明显减弱 ,而呼吸率和乙醇含量明显升高 ,果胶甲酯酶的活性明显增强。浮皮枯水果的若干生理生化指标之间存在显著的相关性

Determination of Physiological Biochemical Indexes of Puffy and Granulated Tangerine Fruit

The physiological biochemical indexes of puffy and granulated tangerine fruit were determined, the results indicated that the density of puffy fruit ranged from 643.0kg/m\+3 to 800.0kg/m\+3 and that of granulated fruit was below 643.0kg/m\+3. In comparison with the normal fruit, the granulated fruit had obviously lower total acid content, moisture content in meat and juice rate and obviously higher respiration rate and ethanol content; in granulated fruit, the activity of catalase abated and that of pectinesterase strengthened markedly. There were significant correlations between some physiological biochemical indexes of puffy and granulated fruit.
