325 Mesh Wood-Based Powdered Activated Carbon for Amino Acid & Vitamin Decolorization with High Decolorization Power and Optimized for Small Molecules

325 Mesh Wood Based Powder Activated Carbon for Amino Acid & Vitamin Decolorization

Product Introduction

Wood-based powdered activated carbon is specially developed for the refining, decolorization, and purification of amino acid and vitamin solutions. It efficiently removes pigments, colloidal substances, fermentation by-products, and trace organic impurities from complex liquid systems, achieving excellent color removal and stability without affecting target molecule yield.

Produced from high-quality hardwood materials through precisely controlled carbonization and activation processes, this fine-grade 325 mesh activated carbon features superior adsorption kinetics and a uniform microporous structure optimized for small-molecule and high-color applications. Its high purity and fine particle size make it ideal for amino acid, vitamin, and pharmaceutical intermediate production.

Note: Specifications and particle sizes can be customized according to customer requirements.

Features· 

• High Decolorization Power: Effectively removes fermentation pigments, amino compound by-products, and colored impurities in vitamin and amino acid solutions.

• Optimized for Small Molecules: The fine 325 mesh structure and high micropore ratio enable rapid adsorption of low-molecular-weight colorants.

• High Purity and Low Ash: Guarantees chemical stability and prevents interference in downstream crystallization or concentration steps.

• Excellent Dispersion and Filtration: Ultra-fine particle size provides uniform suspension and efficient filtration performance with minimal loss of product.

• Pharmaceutical-Grade Quality: Complies with stringent purity standards for use in food-grade and pharmaceutical-grade amino acid and vitamin production.

Applications

• Amino Acid Refining: Used in the purification of lysine, threonine, glutamic acid, and other amino acids produced by fermentation.

• Vitamin Production: Effective in the decolorization and impurity removal of vitamins B₂, B₁₂, C, and other water-soluble vitamins.

• Pharmaceutical and Nutraceutical Industries: Applied in refining intermediates and active ingredients where purity and color control are critical.

• Biochemical Processing: Suitable for removing trace color bodies and odor compounds from fermentation broths and biological filtrates.

Manufacturing Process

• Premium Hardwood Feedstock: Produced from renewable wood sources with low mineral and metallic content.
