  • Patent number: 4046925
    Abstract: A method and composition are provided for preparing a novel acidified milk gel product, characterized by smooth body with no graininess and good flavor. The composition comprises a novel thickener system which is a blend of carboxymethyl cellulose, xanthan gum, and locust bean gum. The thickener is used as a level of from about 0.6-1.6 by weight based on the weight of the final total weight of the milk - acid system. The three components of the thickener composition are present at levels of from about 30% to about 50% for carboxymethyl cellulose, from about 20% to about 50% for xanthan gum, and from about 10% to about 45% for locust bean gum, all percentages as a percent of total weight of the thickener composition. The thickener system can be used for both hot and cold preparations.
