A gel composition comprising 0.1%-6% glucan derived from yeast and 0.2%-3% gelling agent, said composition having a melting point (gel to sol) above 37° C., wherein said gelling agent is a cellulose derivative.
A gel composition comprising 0.1%-6% glucan derived from yeast and 0.2%-3% gelling agent, wherein the gelling agent is a cellulose derivative, and wherein said gel composition is obtainable by a method which comprises:
- a) treating an aqueous solution of glucan molecules derived from yeast, to dissociate the glucan's hydrogen bonds;
- b) treating the aqueous solution to reform hydrogen bonds within the glucan;
- wherein the gelling agent is added prior to step a) or after step a) but prior to step b).
A gel composition comprising a glucan derived from yeast and a gelling agent, said composition having a melting point (gel to sol) above 37° C., wherein said gelling agent is a cellulose derivative and wherein the gel exists in gel form at 25° C. at pH 4 to 8.
A gel composition comprising a glucan derived from yeast and a gelling agent, wherein the gelling agent is a cellulose derivative, wherein the gel exists in gel form at 25° C. at pH 4 to 8, and wherein said gel composition is obtainable by a method which comprises:
- a) treating an aqueous solution of glucan molecules derived from yeast, to dissociate the glucan's hydrogen bonds;
- b) treating the aqueous solution to reform hydrogen bonds within the glucan;
- wherein the gelling agent is added prior to step a) or after step a) but prior to step b).
