Abstract: A process and composition is provided for a hydratable, alloy gum composition of Cassia gum and another gelling and thickening agent which composition is capable of forming a clear, stable colloidal solution. The compositions are usually more easily dispersed in an aqueous solution than either component alone. An alloy gum composition of Cassia gum and xanthan gum is particularly useful for absorbing an aqueous medium.

Abstract: Novel beta-1,3-glucan polysaccharide gels characterized by (a) coherent, uniform, non-particulate structure, and (b) substantially uniform pH throughout. The gels are prepared by dissolving a beta-1,3-glucan polysaccharide in an aqueous alkaline medium at a temperature of about 55 DEG C. or below and while maintaining the solution at a temperature of at least 50 DEG C., adjusting the pH to 10.5 or lower, followed by cooling below about 40 DEG C. or heating above 50 DEG C. The gels formed by cooling are reversible whereas the gels formed by heating are thermally irreversible. The gels are useful for supporting, separating, transforming or treating biological materials, as carriers for pharmaceuticals, as coatings for biological materials, in food products, and can be shaped to form disposable contact lenses.
