  • Patent number: 9249235
    Abstract: Methods of extracting chitin and chitosan from fungal biomass using a solution of one or more ammonia compounds, amines, and/or alkaline silicate compounds. The solution dissolves and extracts amino acids, fatty acids and other carbohydrates from the fungal cells leaving chitin and/or chitosan, and the extractant may be recovered from the liquid by simple phase changes such as heating or cooling, dissociation into volatile components, distillation and/or solidification and separation of immiscible extractants. Further lipid removal may be achieved with one or more organic solvents, which may also be recovered by distillation.
    Type: Grant
