Abstract
Glucosamine, N-acetylglucosamine and β-glucan compositions suitable for human or animal consumption or use are disclosed. The glucosamine, N-acetylglucosamine and β-glucan compositions are derived from fungal biomass containing chitin. Various methods of producing glucosamine, N-Acetylglucosamine and β-glucan compositions are also disclosed.
Claims28
A process comprising:
- providing a source of fungal biomass containing β-glucans, the fungal biomass not comprising yeast;
- treating the fungal biomass with water, heat from about 110° C. to about 200° C., and from about 0.01% to not more than 5% by weight organic acid, to convert at least a portion of the β-glucans into water soluble β-glucans and form a mixture including water soluble β-glucans and treated water insoluble fungal biomass;
- and
- recovering the water soluble β-glucans to form a water soluble β-glucan composition.

A process comprising:
- providing a source of fungal biomass containing β-glucans, and at least about 5% chitin, proteins, and lipids;
- treating the fungal biomass using from about 0.01% to about 5% by weight organic acid and heat from about 110° C. to about 200° C. to hydrolyze at least a portion of the β-glucans into water soluble β-glucans and form a mixture of water soluble β-glucans, water insoluble β-glucans, chitin, proteins, and lipids;
- and
- separating and recovering the water soluble β-glucans from the mixture to form a water soluble β-glucan composition, wherein the water soluble β-glucans in the water soluble β-glucan composition are at least about 20 weight % soluble in water.

A method comprising:
- a) providing a source of fungal biomass having β-glucans;
- b) adding water and from about 0.01 to not more than 5% by weight citric acid, to the fungal biomass to form an about 5% to about 18% solids mixture;
- c) heating the mixture from b) to at least about 110° C. to solubilize at least a portion of the β-glucans;
- and
- d) separating and recovering the water soluble β-glucans from the mixture to form a water soluble β-glucan composition.

A method comprising:
- providing a source of fungal biomass containing β-glucans, chitin, proteins, lipids and from about 0.01% to 5% by weight citric acid;
- adding water and not more than 5% of a second acid, to the fungal biomass to form an about 5 to about 18% solids mixture;
- heating the mixture to at least about 110° C. to hydrolyze at least a portion of the β-glucans;
- separating a filtrate from the mixture, the filtrate comprising a composition including water soluble β-glucans;
- concentrating the composition;
- and
- precipitating the water soluble β-glucans to purify the composition, wherein the composition comprises water soluble glucans having 1,3-, 1,4-, and 1,6-glycosidic linkages.

- treating the fungal biomass with water and about 0.01% to not more than 5% by weight organic acid at a temperature from about 110° C. to about 200° C. to convert at least a portion of the β-glucans into water soluble β-glucans and form a mixture including water soluble β-glucans and treated water insoluble fungal biomass;
- and
- recovering the water soluble β-glucans to form a water soluble β-glucan composition.
