Rapidly soluble fumaric acid compositions comprise particles of fumaric acid of not more than 10 microns and a water-soluble stable anionic or nonionic surfactant. Preferably at least 90% of the fumaric acid is of particle size not more than 10 microns and the proportion of the surfactant is between 0.05 and 3% of the total weight of fumaric acid. Surfactants mentioned are alkyl polyether alcohols, alkyl aryl polyether alcohols, ethylene oxide condensates, compounds of formula <FORM:1071501/C2/1> in which R is an alkyl group and R1 a water-solubilizing group, or alkylphenoxypolyethyleneoxyethanols, or a mixture of a solution of tetramethyldecynediol and an alkyl phenyl ether of polyethylene glycol in ethylene glycol, tetramethyldecyne diol, dimethyldecyne diol, isooctyl phenyl polyethoxy ethanol, polyoxyethylene sorbitan monostearate, nonyl phenyl polyethylene glycol ether, trimethylnonyl polyethylene glycol ether, octyl phenoxypolyethyleneoxyethanol, nonylphenoxypolyethyleneoxyethanol, dioctyl sodium sulphosuccinate, lauryl sodium sulphate and specific compounds are listed. The compositions are prepared by cooling a hot aqueous solution of fumaric acid and the surfactant with ice and filtering and drying, or by mixing the powdered fumaric acid with the surfactant or by micronizing a mixture of the fumaric acid with surfactant. The compositions are suitable for addition to food products, such as beverages.ALSO:Rapidly soluble fumaric acid compositions suitable for use in beverages comprise particles of fumaric acid of not more than 10 microns size and a water-soluble stable anionic or non-ionic surfactant. The compositions are rapidly soluble in cold water and preferably at least 90% of the fumaric acid is of particle size not more than 10 microns and the proportion of the surfactant is between 0.05 and 3% of the total weight. Many surfactants are listed and the preparation described. |
