FIELD: food industry.
SUBSTANCE: invention relates to food industry and involves production of a food additive intended to be used in food mainly for enrichment with iron. The method involves interaction of ferric iron citrate with water and ammonium hydroxide at 55-60°C while mixing until iron citrate is completely dissolved. Mass ratio of the components is 1:(0.3-0.7):(0.30-0.44) respectively. Crystalline citric acid is added at a rate of 8-33% of the iron citrate weight. The stock obtained is stirred until pH is 3.5-5.0.
EFFECT: invention ensures production of iron-bearing food additive which is ferric ammonium (III) citrate green in a bioavailable form with a high yield of the product.
