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.
Claims24
A solid alloy gum composition comprising galactomannan gum extracted by an aqueous medium from seeds of the genus Cassia coprecipitated with a solubilizing quantity of a gelling and thickening agent selected from the group consisting of carrageenan, furacellaran, agar, agarose, agaropectin, dextran, xanthan, algin, carboxymethylcellulose, gellan, low methoxyl pectin, hydroxyethylcellulose, locust bean gum, deacetylated chitin, polyacrylamide, polyethylene glycol and polyvinyl alcohol to form a solid alloy gum composition which forms a substantially clear, stable colloidal aqueous solution on rehydration.
A process for producing a solid hydratable alloy gum composition comprising galactomannan gum extracted from Cassia seeds and a gelling and thickening agent selected from the group consisting of carrageenans, furacellaran, agar, agarose, agaropectins, dextran, xanthan, algin, carboxymethylcellulose, gellan, low methoxyl pectin, hydroxyethylcellulose, locust bean gum, deacetylated chitin, polyacrylamide, polyethylene glycol, and polyvinyl alcohol, the alloy gum composition which forms a substantially clear, stable colloidal aqueous solution, the process comprising:
- extracting seeds of the genus Cassia with an aqueous medium to form a soluble extract portion and an insoluble residue portion, incorporating into the soluble extract portion a solubilizing quantity of said gelling and thickening agent and coprecipitating therefrom a solid alloy gum composition which forms a substantially clear, stable colloidal aqueous solution on rehydration.
A homogeneous solid alloy gum composition which absorbs at least 50 times its weight of an aqueous fluid comprising about equal parts by weight of galactomannan extracted from seeds of the genus Cassia and a xanthan gum.
The process of producing a solid alloy gum composition which absorbs at least 50 times its weight of an aqueous fluid comprising extracting seeds of the genus Cassia with an aqueous medium to produce an aqueous solution of galactomannan solids, separating the aqueous extract portion from the extracted seeds, incorporating into the aqueous extract portion about one part by weight of xanthan gum per part by weight of galactomannan solids, and coprecipitating the alloy gum.
