地牯牛在干燥过程中为防止其褐变，要对其进行护色处理。[方法]鲜地牯牛清洗干净，切成薄片放入护色液，处理一定时间后取出沥干，然后放入烘箱中干燥，用色差仪测产品的色差值。[结果]高浓度的抗坏血酸会引起地牯牛褐变；最佳护色剂组合为氯化钙0.4%，柠檬酸0.5%，氯化钠1%，产品L值为79.78。

In order to prevent browning in the process of drying, we should?study?the color-protecting techniques of Stachys sieboldii Miquell. The fresh cleaned Stachys sieboldii Miquel is?sliced and put into the color protection solution, and is taken out to drain after a certain period of time, then to be dried in the drying oven for 2.5 hours, then it is taken out to determine color by colorimeter. High concentrations of ascorbic acid can cause browning; The best compound color fixative is 0.4% calcium chloride, 0.5% citric acid, 1% sodium chloride, L value of the product is 79.78
