1349404 Encapsulated materials PROCTER & GAMBLE CO 29 June 1971 [29 June 1970] 30411/71 Heading B8C [Also in Divisions A2 and C5] A stable product for use as a food or in preparing foods is made by (1) forming an oil phase from a liquid fat and 0À1 to 10% by weight of acidic lipid (as defined), (2) forming an aqueous phase from water and 1À0 to 50% by weight of protein (as defined), (3) mixing the two phases in a weight ratio of 4 : 1 to 1 : 10 to form an emulsion containing 0À002 to 5À4% by weight of a salt (as defined), and (4) heating to heat-set the protein and optionally to evaporate some or all of the water. The acidic lipid is (a) a long-chain fatty acid, or (b) an oil-soluble salt thereof, or (c) a condensation product of a long-chain fatty acid with a polycarboxylic acid of 3 to 6 carbon atoms and 1 to 4 hydroxyl groups, or (d) a condensation product of a monoglyceride, diglyceride, mixture of diglycerides or monoester of a straight-chain diol (3 to 5 carbon atoms) of a long-chain fatty acid with a polycarboxylic acid of 3 to 6 carbon atoms and 0 to 4 hydroxyl groups, or (e) a gallate of a long-chain fatty alcohol, or (f) a condensation product of a longchain fatty alcohol with a dicarboxylic acid having no hydroxyl groups and 3 to 6 carbon atoms, or (g) a long-chain fatty acid chloride. In all cases, the long-chain fatty acid or fatty alcohol has 12 to 22 carbon atoms, and except in case (g) it is saturated or trans-unsaturated; when the acid lipid is an acid chloride, the acid radical may be saturated or cis- or transunsaturated. The protein is desaturable by heat and either soluble in water or capable of being made so by the aid of heat, chemical or enzymatic treatment without loss of denaturability. The salt is of a polyvalent metal ion, e.g. calcium, and may be derived either from the oil phase (up to 4%) or from the aqueous phase (up to 6%) or from both. When the acidic lipid is a salt, this may also supply the polyvalent metal ions, when the water used is hard, this may supply the ions, when the acidic lipid is an acid chloride, the salt may be omitted altogether. The Specification includes long lists of suitable oils, acidic lipids, proteins and salts. |
