Particulate-soluble glucan preparation
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.

2. The composition of claim 1 wherein the weakly acidic pH is about 5.
3. The composition of claim 1 wherein the weakly basic pH is about 9.
4. The composition of claim 1 wherein the particulate-soluble β-glucan is instantized.
5. The composition of claim 4 and further comprising:
a second dry-form soluble ingredient.
6. The composition of claim 1 wherein the particulate-soluble β-glucan is capable of being re-solubilized in a solution at a temperature of about room temperature or higher.
7. The composition of claim 1 further comprising a surfactant.
8. A composition comprising a dried particulate-soluble β-glucan derived from yeast, having a polydispersed average molecular weight of over about 1,000,000 Da, and capable of being solubilized in a solution having a temperature of about 25° C. or more.
9. The composition of claim 8 wherein the particulate-soluble β-glucan is instantized.
