the model systems are useful for assessing the tinctorial power of food pigments and their concentrations in food.
此模型体系可用于估计着色剂的着色以及在食品中的用量。
the bright coloured product with good tinctorial power and stability was obtained by the crystal transition and surface treatment to carbazole violet, which is prospect.
通过咔唑紫的晶型转变、表面处理,获得性能稳定、着色力强、色泽鲜艳的产品,具有较大发展前途。
we supposed the tinctorial power of the pigments as the ratio of pigment concentrations to the color differences, and discussed a relationship between the ratio values and the pigment concentrations.
