As consumers’ demands for food safety, health, and sustainability continue to rise, the global food industry is accelerating its shift toward “natural, additive-free, and low-pollution” practices. As a natural polysaccharide with multiple functions,
food-grade chitosan stands out for its safety, compliance, and excellent performance, becoming a core raw material for food processing enterprises to optimize product quality and align with market trends. As a professional
exporter of food-grade chitosan, we rely on strict production standards and global distribution capabilities to provide high-purity, customized food-grade chitosan solutions for food enterprises worldwide, helping our partners gain a competitive edge.
Food-grade chitosan is a natural polysaccharide refined from chitin (extracted from the shells of crustaceans such as shrimp, crabs, and lobsters) through deacetylation. It must fully comply with the strict requirements of international food regulatory authorities (e.g., U.S. FDA, European EFSA, and China’s GB standards). Specifically, it requires a deacetylation degree of over 90%, heavy metal content (lead, mercury, arsenic, etc.) below 0.1mg/kg, and microbial indicators (total bacterial count, Escherichia coli, etc.) that meet food-grade limits—all to ensure zero safety risks in food processing.
Compared with chemically synthesized food additives, food-grade chitosan has three core advantages:
Natural biodegradability: It decomposes in the natural environment after use, causing no environmental pollution.
Biocompatibility: It causes no adverse reactions when ingested by the human body and can help regulate the intestinal environment.
Integrated multi-functionality: It can simultaneously achieve preservation, clarification, thickening, fat reduction, and other functions, reducing the types of additives used in food processing and simplifying production processes.
Currently, food-grade chitosan has been widely used in various segments of the food industry, including meat products, aquatic products, beverages, baked goods, and functional foods, earning it the title of “natural versatile all-rounder” in the food industry.
In food processing, enterprises often face challenges such as “short shelf life, unstable quality, difficulties in additive compliance, and obstacles to functional upgrading.” With its unique physical and chemical properties, food-grade chitosan provides targeted solutions to these pain points, becoming the preferred raw material for many food enterprises:
Perishable foods like meat, aquatic products, and eggs are prone to spoilage due to microbial growth during storage and transportation. Food-grade chitosan can effectively inhibit the growth and reproduction of harmful microorganisms (such as Escherichia coli, Staphylococcus aureus, and mold) by damaging microbial cell membranes and inhibiting enzyme activity.
Experimental data shows that:
Adding 0.5%-1% food-grade chitosan to chilled meat can extend its shelf life by 3-5 days.
Adding it to baked goods like bread and cakes can significantly inhibit mold growth, doubling or even tripling the shelf life.
More importantly, as a natural preservative, food-grade chitosan completely avoids safety controversies associated with chemical preservatives (e.g., sodium benzoate, potassium sorbate), meeting consumers’ demand for “preservative-free” food. The food-grade chitosan powder we provide can be directly mixed with food raw materials or made into a solution for spraying on food surfaces, adapting to different food processing techniques without affecting the original flavor and taste of the food.
In the production of beverages such as fruit juice, wine, and fruit wine, impurities like pectin, protein, and tannins in raw materials can cause turbidity, affecting the appearance and taste of the products. Traditional clarification methods (e.g., gelatin clarification, diatomite filtration) may leave chemical residues and easily absorb nutrients such as vitamins and anthocyanins in beverages.
Food-grade chitosan has excellent adsorption and flocculation capabilities. It can form stable flocs with impurities in beverages, which are easily removed through filtration—without damaging the nutrients and natural flavor of the beverages. For example, adding 0.2%-0.3% food-grade chitosan to apple juice processing can increase the juice’s light transmittance to over 95% (far higher than the 80% of traditional processes) while improving the retention rate of vitamin C by 15%-20%.
To meet the needs of beverage enterprises, we provide food-grade chitosan with different particle sizes, adapting to the clarification requirements of various products (fruit juice, wine, plant-based protein drinks, etc.) and helping enterprises produce high-transparency, nutrient-rich premium beverages.
As the “healthy eating” trend gains momentum, functional foods with low fat, controlled sugar, and high fiber have become market hotspots. Food-grade chitosan has unique value in functional foods:
Fat adsorbent: It binds with fat in the human intestine to form non-absorbable complexes, reducing fat intake—suitable for the production of low-fat meal replacements and weight-loss foods.
Dietary fiber source: It promotes intestinal peristalsis and improves intestinal flora, making it ideal for probiotic foods and elderly-friendly foods.
Sugar control auxiliary ingredient: It slows down the decomposition and absorption of carbohydrates, helping stabilize blood sugar—suitable for the development of diabetes-friendly foods.
Our food-grade chitosan has passed multiple functional tests. We can provide products with different deacetylation degrees according to customer needs:
High deacetylation degree products: Stronger fat adsorption capacity, suitable for low-fat foods.
Medium deacetylation degree products: Better solubility, suitable for oral liquids, meal replacement powders, and other formulations.
This provides core support for functional food enterprises in product innovation.
In the preservation of fresh foods (e.g., fruits, vegetables, eggs), food-grade chitosan can be made into edible coatings, forming a breathable, waterproof film on the food surface. This film not only prevents moisture evaporation (maintaining the food’s tender texture) but also isolates oxygen (inhibiting oxidative spoilage) and slowly releases antibacterial components (further extending the shelf life).
For example:
Spraying a food-grade chitosan coating on strawberries can extend their room-temperature storage life from 2-3 days to 5-7 days.
Coating eggs with it can effectively block bacterial invasion, extending the shelf life by over 1 month.
In addition, food-grade chitosan can be used as a modifier for food packaging materials. When mixed with materials like polyethylene and polylactic acid, it enhances the packaging’s antibacterial properties and biodegradability, reducing environmental pollution from plastic packaging. We provide food-grade chitosan coating raw materials in liquid and powder forms according to the preservation needs of food enterprises, and offer technical support to help optimize coating processes.
As an enterprise focusing on the R&D, production, and export of food-grade chitosan, we deeply understand food customers’ needs for “safety, stability, compliance, and efficiency.” We have become a trusted partner of food enterprises worldwide by virtue of the following advantages:
We use certified high-quality chitin raw materials and produce food-grade chitosan through four core processes: deacetylation, purification, refinement, and sterilization. Each batch of products undergoes testing by third-party inspection institutions, and we provide complete test reports—ensuring compliance with international and domestic standards such as the U.S. FDA, European EFSA, and China’s GB 28404-2012 National Food Safety Standard for Food Additive Chitosan. This eliminates customers’ concerns about compliance risks.
Different food categories have vastly different processing techniques and product characteristics, leading to varying requirements for the form, particle size, and solubility of food-grade chitosan. We can provide food-grade chitosan in powder, granular, and liquid forms, and adjust the deacetylation degree and purity according to customer needs—ensuring the raw material perfectly matches the customer’s production process.
