  • Patent number: 11602153
    Abstract: This invention relates to making and using a stabilizer that is effective in small amounts and, particularly useful for stabilizing low solids liquids, e.g., dispersions, emulsions, and suspensions, used in foods, pharmaceuticals, nutraceuticals, and similar industrial applications, which comprises, microcrystalline cellulose, (preferably, colloidal hydrolyzed MCC); a first carboxymethyl cellulose having a viscosity of 30-85 cP at 2% in deionized water; and, a degree of carboxymethyl substitutions of 0.60 to 0.85, and a second carboxymethyl cellulose having a viscosity of 400-800 cP at 2% in deionized water, and a degree of carboxymethyl substitutions of 0.80 to 0.

  • Patent number: 10694765
    Abstract: A method of making a water-dispersible composition comprises coprocessing a microcrystalline cellulose wetcake and at least one starch by co-attrition to form an admixture comprising colloidal microcrystalline cellulose and said at least one starch. The admixture is subsequently dried. Optionally, the admixture may be combined with an additional hydrocolloid, such as a galactomannan, before or after drying. A dried colloidal microcrystalline cellulose composition may then be dispersed in an aqueous media to form the food/beverage product. In particular, the composition may be dispersed in an aqueous media containing, for example, a protein to form a low pH beverage composition.

  • Patent number: 9895672
    Abstract: The invention is directed to a seamless alginate capsule having a film encapsulating a fill material, in which the film comprises alginate, noncrystallizing plasticizer, and glycerol and in which a ratio by weight of noncrystallizing plasticizer to glycerol in the film is between about 1:1 and about 8:1. The invention is also directed to a method of making the seamless alginate capsules and to capsules made by the method. The capsules have excellent breaking strength and are resistant to oxidation of the fill material.
