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

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