Disclosed are an improved cold water soluble gelatin and a process of preparing it. The gelatin is prepared by drying an aqueous solution comprising gelatin, a hydrolysed corn starch having a dextrose equivalent of 20-36 (preferably of the order of 26, and less preferably a maltodextrin having a dextrose equivalent of about 5 to about 20), an acid, and amount of surface-active agent effective to increase dispersibility in the final product. An optional, but preferred, feature comprises holding the aqueous solution at an elevated temperature prior to the drying step, the acid being incorporated in the solution either before or after the holding period. After drying, the material is preferably reduced to a particle size from about 20 to about 200 US mesh wherein at least about 40 percent by weight of the particles will pass through US mesh greater than 100. The cold water soluble gelatins are characterized by improved solubility and ease of dispersion in water as well as by the clarity of the gels produced therefrom. |
