Core Technical Advantages

Material characterization & quality assurance

>>>

Excellent Water Solubility

Unlike regular chitosan, which only dissolves in dilute acidic solutions, carboxymethyl chitosan dissolves readily in cold water to form a stable solution, making it highly versatile for various formulation processes.

Multi-Functional Additive

Combines thickening, emulsifying, stabilizing, water-retaining, and film-forming functions in a single ingredient, effectively reducing the need for multiple additives in complex formulations.

High Purity & Consistency

Strictly controlled degree of substitution, viscosity, and microbial indicators. Every batch is accompanied by a COA report, ensuring consistent quality and full batch-to-batch traceability.

Reliable Bulk Supply

Equipped with scaled manufacturing capabilities, supporting flexible order quantities from kilogram to ton-scale. Meeting the raw material procurement needs of food processors and supplement brands.

Mechanism of Function

Functional properties for formulation design

Thickening Agent

Forms high-viscosity fluids in aqueous solution, suitable for sauces, beverages, dairy products, and other food systems. Provides smooth mouthfeel and stable texture across a wide pH range.

Stabilizer & Emulsifier

Helps maintain uniform dispersion of oil-water phases in food systems, preventing separation and sedimentation. Extends product shelf life by enhancing formulation stability.

Nutrition Enhancer

As a chitosan derivative, it exhibits properties characteristic of dietary fiber-type substances. Suitable for use as a functional component in nutrition-enhanced food formulations.

Film-Forming Agent

Forms breathable protective films on food surfaces, applicable for fresh-keeping coatings and edible packaging materials, extending product freshness while maintaining quality.
