. The influence of a food additive“Magneftofud” (nanopowder of double oxide of two- and trivalent Ferum) on physical and chemical parameters, functional and technological properties of model beef minced meat have been studied. Also, their organoleptic parameters and the output of ready steaks made from them were investigated. Food additive “Magnetofood” was added to the beef minced meat in the amount of 0.05–0.15% to the mass of meat raw material. The water-binding ability was determined by the method of pressing; degree of oxidation by means of peroxide and acid numbers; output of the finished product and organoleptic indicators – by standard and commonly accepted methods; digestion of proteins of steaks – by the method of Pokrovsky A.A. and Yertanova E.D. It has been determined that due to the nanosize of Ferum oxide , a significant specific volume, developed active surface, affinity for proteins, thermal stability, the additive “Magnetofood” has antioxidant, sorption, complexing, structure-forming, stabilizing, water-binding, water and fat-retaining properties. Thus, the investigated additive contributes to the formation of new functional and technological indicators of beef meat systems and the improvement of consumer characteristics of the finished products obtained from them. The input of "Magnetofood" food additive in beef minced meat improves the organoleptic and functional-technological parameters compared to control: the moisture-binding capacity increases by 12.0–12.8%; output of finished products - by 1,5–4,5%. The growth of the total effect of digestion of proteins of prepared steaks (in 1,17-1,65 times) have been noted; reduction of the acid number (by 3,0–4,0%) and peroxide number (by 0,09–0,12 mmolol/kg). The results of the studies allowed to determine the rational amount of food supplement “Magnetofood”, it is 0.15% to the mass of meat raw materials.
