Claims
- 1. A method of preparing powders and granules capable of forming, in cold water with only mild agitation, a stabilized dispersion of a difficult to disperse organic material; said method comprising bringing together a difficult to disperse material and dry particles consisting essentially of beta-1,4 glucan having intimately associated therewith from about 1 to about 30 parts by weight of a water-soluble polymer, and mixing the difficult to disperse material and the dry particles in the absence of water for such time that the difficult to disperse material forms a substantially dry incomplete coating on said particles.
- 2. In the method set forth in claim 1 wherein said difficult to disperse material is normally solid at room temperature, the steps of applying heat to said material to liquify the same before bringing said material and said dry particles together, and discontinuing the application of heat during mixing.
- 3. An article comprising a core component and a skin component substantially but not completely encapsulating said core component, said core component consisting essentially of from about 70 to about 99 parts, by weight, of disintegrated beta-1,4 glucan and from about 1 to about 30 parts, by weight, of a water-soluble polymer intimately associated with the disintegrated beta-1,4 glucan and said skin component being an organic material that is difficult to disperse in water.
- 4. The article set forth in claim 3 wherein the beta-1,4 glucan constitutes from about 85 to about 95 parts of the weight of the core component and the water-soluble polymer constitutes from about 5 to about 15 parts of the weight of said core component.
- 5. The article set forth in claim 4 wherein said water-soluble polymer is sodium-carboxymethyl cellulose.
- 6. The article set forth in claim 5 wherein the sodium carboxymethyl cellulose has a degree of substitution of 0.75.+-.0.15.
