Food grade chitosan can serve as a binder, humectant, clarifying agent, filler, emulsifier, glazing agent, and thickening stabilizer in the food industry. As a functional oligosaccharide, Chitosan can reduce cholesterol, enhance immunity, improve disease and infection resistance, and exhibits significant antitumor activity. Due to its abundant resources and high application value, it has been extensively developed and utilized.
As a professional manufacturer and supplier of chitosan, Tianya Chemical is committed to providing high-quality food grade chitosan products that meet international standards, catering to the diverse needs of the food industry. We strictly control raw material sourcing and production processes to ensure product safety, stability, and excellent performance.
Applications of Food grade chitosan
1. Chitosan for enzyme immobilization carrier
Chitosan acetic acid solution is sprayed into alkaline solution for coagulation. After separation and regeneration, chitosan micro-particles are obtained, which can serve as carriers for immobilized enzymes. Enzymes immobilized by chitosan can be used in bio-preparation engineering such as sugar production, brewing, vinegar making, and protein hydrolysis. Tianya Chemical’s food grade chitosan, with high purity and controllable particle size, is an ideal raw material for preparing efficient immobilized enzyme carriers.
2. Chitosan for food additive
Microcrystalline chitosan can be used as a thickener and stabilizer in the production of seasonings such as mayonnaise, peanut butter, sesame paste, canned corn puree, and cream substitutes. Typically, long-stored vinegar develops sediment mainly due to metal ions forming macromolecular complexes with tannins and other phenolic acids. Vinegar treated with chitin and chitosan shows no precipitation after one year of storage. Adding appropriate amounts of chitosan during soy sauce production removes proteins and prevents sedimentation. Adding small amounts of chitosan to fermented soybean paste reduces salt content while maintaining product stability during long-term storage. Tianya Chemical offers food grade chitosan additives in various specifications to help food producers enhance product quality and shelf life.
3.Chitosan for food packaging film
Chitosan and starch are uniformly mixed with water to form a film. After drying and alkaline treatment, a chitosan-starch composite food packaging film is produced. This film is non-toxic, edible, oil-resistant, insoluble in cold/hot water, and has high tensile strength. It can package solid, semi-solid, and liquid foods. The film biodegrades naturally, eliminating white pollution. Food grade chitosan produced by Tianya Chemical is a premium base material for developing biodegradable, eco-friendly food packaging films. We can provide customized solutions based on customer requirements.
4. Chitosan for food preservation
Food grade chitosan can be used for preserving vegetables, meat products, seafood, starches, soybean products, as well as eggs, dairy, and bean products.
After harvest, fruits and vegetables undergo physiological ripening, causing them to soften. This results in decreased firmness, difficulties in transportation, reduced quality and nutritional value, and weakened resistance to bacteria. Therefore, how to preserve fruits and vegetables has long been a concern. Chitosan possesses film-forming properties, is not only harmless to humans but also has physiological health benefits. Its protective effect on fruits and vegetables has gained increasing recognition. Covering the surface of fruits and vegetables with chitosan reduces transpiration and provides selective gas permeability. It blocks external O₂ from entering the film, increases CO₂ content within the fruit/vegetable tissues, and reduces ethylene release. Consequently, this lowers respiratory metabolism intensity, delays ripening, and achieves preservation.Tianya Chemical provides chitosan products specifically designed for fruit and vegetable coating applications.
Food grade chitosan demonstrates significant preservative effects on chilled pork. Higher deacetylation degrees of chitosan yield better preservation results for chilled meat. A 1% chitosan solution dissolved in 1% acetic acid extends the shelf life of chilled meat to one week while maintaining good sensory quality. The preservative effect of a 2.5% water-soluble chitosan solution is slightly lower than that of 1% acid-soluble chitosan, but chilled meat samples treated with water-soluble chitosan completely lack acidity and exhibit favorable sensory quality.Tianya Chemical supplies food grade chitosan with varying deacetylation degrees (DD) and solubility (acid-soluble, water-soluble) to meet the preservation process requirements for various meat products.
For seafood rich in unsaturated fatty acids, food grade chitosan serves as an excellent natural antibacterial and antioxidant agent. Chitosan of varying molecular weights prepared from snow crab, at concentrations of 50-200 mg/kg, effectively controls lipid oxidation in cod fish during cooking. Higher concentrations result in stronger antioxidant capacity. Tianya Chemical offers food grade chitosan in multiple molecular weight specifications, providing a reliable choice for seafood preservation and quality control.
