Red40 Manufacturing Process


Manufacture of Red 40
Red 40 is a commonly used colorant. Its manufacturing method is especially exquisite.

At the beginning, appropriate organic compounds are taken, mostly from coal tar and so on. These raw materials are finely refined to remove their impurities and retain their usable quality.

Then, the steps of chemical synthesis are carried out. In a special reactor, according to a precise formula, various chemical reagents are added to control the temperature, pressure and reaction time. The specific chemical reaction between the raw materials will gradually give rise to the embryonic form of Red 40.

After synthesis, it is separated and purified again. By filtration, distillation, crystallization and other methods, Red 40 is purified from the reaction product to remove other impurities and maintain the purity and quality of its colorant.

Finally, the purified Red 40 is dried and ground according to specific specifications to make a suitable commercial form, either as a powder or as a granule, for use in food, medicine, cosmetics and other industries.

The manufacturing process of Red 40 is interconnected, and rigorous operation and exquisite skills are required to obtain this colorant with bright color and high quality.
