Chitosan is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating the chitin shells of shrimp and other crustaceans and cell walls of fungi (Mushroom, Agaricus Bisporus, Aspergillus Niger) with an alkaline substance, like sodium hydroxide.
Chibio Chitosan, in keeping with its natural, clean label mantra, uses chitosan only from Agaricus Bisporus Mushroom and Aspergillus Niger! Just like the types of mushrooms you can find in your local grocery stores such as oyster and White Button Mushroom.
Mushroom/Aspergillus Niger chitosan is suitable for a wide variety of dietary restrictions. This includes vegan, kosher, halal diets and most importantly it does not contain allergens, making it safe for everyone.
