不同原料颜色对高粱红色素理化性质的影响

Effect of different raw material color on physical and chemical properties of sorghum red pigment

分别采用红色和黑色两种颜色高粱壳为原料提取高粱红色素,对其理化性质分析比较,可知黑壳色素提取率为5.2%,色价45,耐热性能好,色调为紫褐色,色泽较暗;红壳色素提取率为3.1%,色价32,色调为红棕色,色泽较亮。

Sorghum red pigment extracted from red and black properties result was that the pigment extraction rate of black resistance was good,hue was purple and brown,color and lustre was 3.1%, color value was 32, hue was reddish brown, colour and color sorghum shell,physical and chemical shell was 5.2% ,color value was 45,heat was dark. Pigment extraction rate of red shell lustre was more bright.
