A method for the production of a granular, free-flowing, non-dusting food acid composition having a preselected taste profile which can be used as a citric acid replacement in a foodstuff, the method including the steps of combining fumaric acid with an organic acidic material selected from malic acid, tartaric acid, citric acid, lactic acid, ascorbic acid and mixtures of any two or more thereof in an aqueous medium to produce a mixture; and granulating the mixture to produce a food acid comprising a granular product material containing fumaric acid and the organic acidic material, the quantity of fumaric acid and the quantities of the organic acidic material being selected so that the fumaric acid makes up between 5% and 95% of the granular product, the combining step: being selected from one of grinding the fumaric acid in an aqueous solution of the organic acidic material to produce a slurry; and grinding the fumaric acid in an aqueous medium to produce a milled fumaric acid slurry and then adding the organic acidic material to the milled fumaric acid slurry; the granulating step being a spray granulating step which is controlled to produce a free-flowing granular product having a particle size of 20-60 mesh. |
