【 摘 要 】

The object of research is the technology of oatmeal cookies using the Magnetofood food additive. Prospective enhancers of food systems (in particular, dough confectionery masses) are nanoadditives, which are characterized by a wide range of functional and technological properties, due to the specificity of their physico-chemical characteristics due to nanoscale size and quantum-mechanical effects.In order to study the influence of the Magnetofood food additive on the functional and technological properties of the dough and the quality indicators of Magnetofood oatmeal cookies additive was injected into the formulation in the form of a fatty suspension at the stage of «oil rubbing». It was established that the administration of the Magnetofood food additive in the formulation of oatmeal cookies in the amount of 0.1; 0.15; 0.2 % of the weight of the prescription mixture as a fatty suspension (as compared to control) contributes to:– increase in the moisture content of the dough (1.2±0.2) %, the stress of the dough shift – by (20±2) Pa and the plastic viscosity of the dough – by (2.2±0.4) kPa·s;– reduction of the dough density on (0.6±0.1) g/cm3;– increase of humidity of oat cookies – by (2.25±0.1) %, typical cookie on (10±2) %, the yield of the cookie – by (2.0±0.5) %, the average value of the ball scoring of the cookie by the organoleptic analysis – by (1.0±0.1) points, improvement of the chewing of the cookie – by (0.4±0.2) points;– decreasing the density of the cookie on (0.10±0.02) g/cm3, bread crumbling – by (0.9±0.2) %, losses at heat treatment on (1.8±0.2) % and alcohols of the cookie on (0.3±0.1).Compared with similar well-known enhancers of food systems, nanoobjects, which include nanopowders (Magnetofood), have enormous potential and carry many important discoveries, new functional and technological properties and promising technological applications. The interaction of Magnetofood nanoparticles with biopolymers is a complex of complex chemical reactions. The result is the formation of spatial nanostructures, which significantly affect the functional and technological properties of raw materials and semi-finished products. In food systems, such additives, in particular Magnetofood, exhibit antioxidant, bacteriostatic, sorption, emulsifying, structure-forming, moisture and fat-retaining properties. This ensures the possibility of obtaining high values of the investigated indicators.
