METHOD OF MANUFACTURING COMPLEX ADDITIVE BASED ON FINE GRAINED CHALK Russian patent published in 2008 - IPC A23L1/30 A23L1/304 A23K1/16 

FIELD: food products.

SUBSTANCE: invention relates to feed and food industry and can be used for manufacturing of natural activated complex chalk-based additive. Method of manufacturing complex additive based on fine grained chalk involves grinding original chalk, making suspension, adding dispersant in the form of sodium salt, sorting into coarse and fine fractions and fine grinding. Sodium citrate is added as dispersant at this phase. Fine grinding implies separate grinding of coarse and fine fractions till particle size is 10 mkm at most. Then finely ground product of each fraction is activated separately by passing its suspension as turbulent flow through ultraviolet field. The invention allows manufacturing of complex additives in the form of two fractions having increased digestibility, iodine bioavailability and antioxidant properties.

EFFECT: manufacturing of food additive with increased digestibility and antioxidant properties.
