Product Introduction
Chitosan Oligosaccharide Powder is a natural oligosaccharide produced from food-grade chitosan through enzymatic hydrolysis, separation, and spray drying. Unlike standard chitosan, this product has a molecular weight ≤3000 Da, is highly water-soluble and completely soluble in water, with an absorption rate approaching 100%. It combines natural preservation, gut prebiotic, immune modulation, and heavy metal chelation functions, making it a multifunctional natural food ingredient integrating preservation, nutrition, and health. Its core value lies in its excellent water solubility and high biological activity, helping food and beverage companies develop differentiated products with both natural preservation and gut health/immune support claims, making it a rare "preservation + health" dual-action natural ingredient in the food industry.

Health Benefits & Values
Clean-Label Natural Preservative
Provides broad-spectrum inhibition of bacteria, fungi and yeast, partially replacing synthetic preservatives to enable cleaner ingredient lists.
High-Activity Gut Prebiotic
Selectively nourishes beneficial gut bacteria to balance intestinal microflora. Low-molecular-weight grades offer high bioavailability for gut-health supplement development.
Dual Immune and Antioxidant Support
Scavenges free radicals and boosts immune response. It also slows food oxidation, adding immune-support benefits to functional food and supplement formulas.
Binds Toxins, Heavy Metals and Lipids
Amino and hydroxyl groups adsorb heavy metals, excess fat and cholesterol to reduce harmful impurities in food and nutritional formulations.
Edible Coating for Produce Preservation
Forms a breathable protective layer on fruits and vegetables, slowing respiration and spoilage to retain moisture and extend shelf life.
Core Value in Formulation Development
Excellent Water Solubility for Convenient Formulatio
Unlike chitosan which requires dilute acid for dissolution, chitosan oligosaccharide is directly soluble in water, yielding a clear solution without acidic media, simplifying formulation operations for various food systems.
Multifunctional Integration
Integrating preservation, prebiotic, immune modulation, heavy metal chelation, and film-forming preservation in one ingredient, satisfying multiple formulation functions and reducing ingredient count and procurement costs.
Aligning with Clean Label and Functional Food Trends
Chitosan Oligosaccharide Powder as a natural functional ingredient, chitosan oligosaccharide can replace some chemical preservatives while imparting "gut health" and "immune support" functional claims, helping brands build differentiation in clean label and functional food segments.
Compatibility with Common Food Ingredients
Compatible with common ingredients in dairy, beverages, bakery, and meat systems without adverse interactions. Chitosan oligosaccharide is stable across acidic to neutral pH ranges, with strong formulation adaptability.
Stability Considerations
This product is hygroscopic and should be sealed and stored in a cool, dry, dark place to prevent caking. It is stable in aqueous solutions; prepare fresh or store refrigerated.
End-Application Scenarios
Functional Foods and Health Foods (Core Track)
Used in gut health, immune support, and weight management functional foods and health foods. As a prebiotic, chitosan oligosaccharide promotes Bifidobacteria proliferation, improves gut flora balance, and enhances immunity.
Dairy Products and Functional Dairy Beverages
Used in yogurt, modified milk, and functional dairy beverages to promote calcium and mineral absorption while improving product texture and shelf life.
Bakery and Cereal Foods
Used in bread, biscuits, and pastries. Chitosan oligosaccharide inhibits spoilage microorganisms, retards starch retrogradation, maintains product softness and mouthfeel, and extends shelf life. Particularly suitable for "high-fiber" and "healthy bakery" concept products.
Meat and Seafood Preservation
Used for preservation, water retention, and antioxidant treatment of fresh meat, seafood, and single-frozen fish fillets. Chitosan oligosaccharide inhibits spoilage and pathogenic bacteria, delays fat oxidation, extends shelf life, and reduces transport and storage losses.
Fruit and Vegetable Coating Preservation
Used for coating preservation of strawberries, kiwis, and cherry tomatoes. Chitosan oligosaccharide coating significantly reduces fruit decay rate and weight loss, maintains higher soluble solids and vitamin C content, and delays fruit softening.
Natural Preservation for Condiments
Used for natural preservation of soy sauce, vinegar, and sauces. Chitosan oligosaccharide can replace chemical preservatives like sodium benzoate while achieving clean label formulations.
Application Advantages and Market Positioning
Significant Water Solubility Advantage
Chitosan oligosaccharide powder is the most water-soluble form in the chitosan series, directly soluble in water without dilute acid, offering convenient formulation and application across solid and liquid food systems.
Multi-Function Positioning for Product Differentiation
One ingredient covers preservation, gut health, and immune support, enabling brands to differentiate in functional food markets.
Dual Preservation and Health Positioning
Combines natural preservation with gut health and immune support in one ingredient.
Authoritative Compliance Assurance
Chitosan oligosaccharide has been approved as a new food raw material by China's National Health Commission, with a daily intake ≤0.5 g/day, usable in various foods except infant foods. Strong compliance and market access.
FAQ (Technical Q&A)
Q1: Is chitosan oligosaccharide stable in acidic beverages?
A: Yes. It is stable in acidic conditions and does not degrade. Suitable for fruit juices and acidic functional drinks.
Q2: Does chitosan oligosaccharide cause precipitation when blended with proteins?
A: It may interact with anionic proteins at high concentrations. Small-scale compatibility testing is recommended before scaling up.
Q3: Does chitosan oligosaccharide affect the clarity of transparent beverages?
A: It is water-soluble and forms clear solutions at recommended dosages. It does not cause haze or sedimentation.
Q4: How does the antimicrobial spectrum of chitosan oligosaccharide compare to potassium sorbate or sodium benzoate?
A: It has broad-spectrum activity against bacteria, fungi, and yeast, while potassium sorbate and sodium benzoate mainly target fungi and yeast. It can partially replace them in clean-label formulations.
Q5: Is chitosan oligosaccharide safe for consumers with shellfish allergies?
A: It is derived from shrimp or crab shells. Highly purified grades may have low allergenicity, but labeling should indicate the shellfish source for allergen awareness.
Q6: Is chitosan oligosaccharide heat-stable during baking?
A: It is stable at moderate baking temperatures. Prolonged exposure above 180°C may cause degradation; adding after baking is recommended when possible.
Q7: How is chitosan oligosaccharide applied in meat preservation?
A: Use as a dip or spray at 0.5%–1% solution. It inhibits spoilage bacteria and delays oxidation.
Q8: Can chitosan oligosaccharide powder be used together with probiotics?
A: Yes. It acts as a prebiotic and may support probiotic growth. No adverse interaction observed.
Q9: What should be noted when replacing sodium benzoate with chitosan oligosaccharide in condiments?
A: Chitosan oligosaccharide is less effective in very acidic or high-salt systems. Adjust dosage and test stability in the final product.
Q10: Does chitosan oligosaccharide affect the color of finished products?
A: It is pale yellow to off-white and does not significantly alter color at recommended dosages.
Q11: Is chitosan oligosaccharide stable in alcoholic beverages?
A: It is stable in low-alcohol systems. High alcohol content may reduce solubility; testing is recommended.
Q12: What is the effective prebiotic dosage of chitosan oligosaccharide?
A: Prebiotic effects are typically observed at 0.1%–0.5% in functional foods. Specific dosage depends on the food matrix and target claims.
