Abstract

Particulate β-glucan is solubilized at elevated pressure and temperature to form particulate-soluble β-glucan. The particulate-soluble β-glucan is capable of being dried to a powder form and subsequently re-solubilized.

Claims (11)

1. A composition comprising a particulate-soluble β-glucan derived from yeast and capable of being dried to powder form and then being re-solubilized in a solution having a pH of about 5 or more.

2. The composition of claim 1 wherein the particulate-soluble β-glucan is instantized.

3. The composition of claim 2 and further comprising:

a second dry-form soluble ingredient.

4. The composition of claim 1 wherein a temperature of the solution is about room temperature or higher.

5. A composition comprising a particulate-soluble β-glucan derived from yeast and capable of being dried to powder form and then being re-solubilized in a solution having a temperature of about 25° C. or more.

6. A composition comprising a particulate-soluble β-glucan derived from yeast, wherein the particulate-soluble β-glucan is instantized and, if dried, is soluble in a solution having a pH of about 5 or more.

7. The composition of claim 6 and further comprising:

a second dry-form soluble ingredient.

8. The composition of claim 6 wherein a temperature of the solution is about room temperature or higher.

9. The composition of claim 6 wherein the particulate-soluble β-glucan has an average molecular weight of over about 1,000,000 Da.
