Refined Decolorization of Powdered Activated Carbon

The refined decolorization of powdered activated carbon primarily refers to its use in the food and pharmaceutical industries for purification and decolorization. In the food industry, the most widely applied and mature type is wood-based carbon, mainly produced using the phosphoric acid method.

This type of powdered carbon features a developed mesoporous structure and high specific surface area, providing large adsorption capacity, fast filtration rate, and a zinc-free composition.

It is widely used in the food industry for the decolorization, purification, deodorization, and impurity removal of products such as:

Sugars, glutamate and salts
Lactate and salts
Citric acid and salts
Wine
Seasonings
Animal and plant proteins
Biochemical products
Pharmaceutical intermediates
Vitamins
Antibiotics

Refined powdered activated carbon ensures high efficiency and quality in processing, making it a key material in food and pharmaceutical production.
