| 摘 要： | 采用CIELab表色系对干燥金银花的颜色劣变现象进行分析,结果表明,金银花在热风干燥过程中影响颜色劣变的因素是酶促褐变,以及叶绿素在热风干燥过程中的损失。绿原酸是酶促褐变中酶的底物,反应需要氧气参与,叶绿素的损失不仅使金银花原有颜色发生改变,生成的褐色物质也可以加重金银花褐变程度。

| Abstract: | The CIELab color system is used to analyse the variaty of dry honeysuckle color,the reason of honeysuckle color change during hot air drying has been attained:enzymatic browing and the loss of chlorophyll play an importmant role,oxygen and chlorogenic acid are involed in enzymatic browing.The loss of chlorophyll not only changes the color of honeysuckle,but also intensifies the degree of browing. |
