Chitosan (E244) – what is it?
Chitosan, designated as E244, is a natural preservative and antioxidant of organic origin. It is extracted from chitin – a polysaccharide found in the shells of crustaceans such as shrimp, crabs and lobsters. Thanks to its antibacterial and stabilizing properties, chitosan is valued in the food industry as an effective additive for extending the shelf life of products.
Properties of chitosan (E244)
Chitosan is a multifunctional substance that acts as both a preservative and a texture enhancer for products. It exhibits strong antibacterial and antifungal properties, thus preventing the growth of microorganisms and delaying food spoilage. It is a natural polymer that, when in contact with water, forms a thin, protective layer on the surface of food products, which further supports their shelf life.
E244 is also known for its chelating properties, which allows it to bind heavy metals and prevent their negative impact on food quality. As a result, it helps preserve the freshness of products and their attractive appearance.
Use in food products
Chitosan (E244) is used in a wide range of food products where extending shelf life and protection from microorganisms is crucial. It is particularly popular in meat and fish preparations, where it acts as a preservative, preventing fat oxidation and bacterial growth.
In the baking industry, E244 is used to improve the texture of cakes and breads, giving them better elasticity and shelf life. In the fruit and vegetable industry, chitosan is sometimes used as a natural protective coating that prolongs the freshness of fruits and vegetables, preventing them from drying out and rotting.
Health and environmental benefits
E244 is valued not only for its preservative properties, but also for its sustainability. Chitosan is derived from natural raw materials, and its biodegradability makes it environmentally friendly. In a health context, it shows potential benefits, such as lowering cholesterol and supporting gut health, which also makes it sometimes used as an ingredient in dietary supplements.
Why is E244 valued?
Chitosan (E244) is a unique additive that combines effective preservative action with an eco-friendly character. Its natural origin, biodegradability and versatility in applications make it a popular choice for organic food manufacturers and those who emphasize the sustainability and safety of their products.
