METHOD FOR PRODUCTION OF IRON LACTATE DIETARY SUPPLEMENT Russian patent published in 2012 - IPC A23L1/30 A23L1/304 C07C69/68 

FIELD: food industry.

SUBSTANCE: invention relates to food industry and refers to production of a dietary supplement intended for using in food products, primarily - for enrichment with iron. The method includes interaction of water solution of sodium lactate with concentration equal to 58.2-61.4 wt % with water solution of heptahydrate iron sulphate with concentration equal to 40-50 wt % (in the process of stirring) during 1.5-2.5 hours at a temperature of 35-45°C in carbon dioxide or hydrogen resulting in iron lactate crystals formation. The weight ratio between the water solutions of sodium lactate and iron sulphate is 1:(1.42-1.88). The produced iron lactate crystals are separated from the drinking water till complete absence of sulphates in The flush water. Then iron lactate crystals are dried under vacuum with depression equal to at least 94 kPa at a temperature no more than 70°C.

EFFECT: invention allows to produce an iron lactate dietary supplement with improved quality and a high product output.
