Product Description

Sorghum red pigment is extracted from sorghum husks as raw materials. Bright color and strong coloring power.
This product can be used as food and cosmetic additives.
This product uses sorghum husk as the starting material, and is first pre-treated with inorganic acid, i.e., soaked in dilute hydrochloric acid or boiled in dilute hydrochloric acid. Dilute hydrochloric acid used in the mass concentration of 0.5% to 5%, the soaking time and temperature should correspond to the concentration of acid. The higher the concentration the lower the hydrochloric acid concentration and temperature used.
Acid treatment of sorghum shells into organic solvents to extract pigments, extraction temperature can be from room temperature to 100 ºC, the higher the temperature extraction rate and extraction rate are higher, preferably in the boiling point of ethanol, at this time, the extraction rate is fast, and do not have to use special equipment. Extraction equipment is generally used fat extractor.
With organic solvents to extract sorghum shells obtained after the extract for the deep purple-red liquid, and then use the method of distillation to evaporate the solvent. When the solvent will end, most of the liquid remaining in the distillation flask is water, at this time sorghum red pigment can be self-crystallization precipitation, after filtration and separation will be obtained after the solid product.
