Fortification of recipes for products containing only refined raw materials, such as ice cream wafer cups, is a modern trend for such products. The use of soy okara in wet and dry form for these purposes allows you to unlock the potential of this raw material as an improver in the quality of wafer products. In the cup recipe, soy okara was added instead of flour dry matter in the amount of 10–30% in increments of 5%. In the wafer dough the mass fraction of moisture and spreadability were determined, in finished products - the mass fraction of moisture and wettability. It has been established that the use of wet and dry soy okara instead of the dry matter of flour in the formulations of wafer cups for ice cream allows increasing the moisture content of the dough by 2.3–4.9% and 3.6–8.8% and reducing its spreadability by 2–13 mm and 2–7 mm, respectively. In finished wafer cups, the introduction of wet and dry soy okara contributes to an increase in the mass fraction of moisture by 0.1 - 0.4% and 0.1 - 0.9%, a decrease in wetness by 2 - 22% and 2 - 15%, respectively, compared with the control sample. Rational dosage was taken 15% of dry soy okara and 20% dry soy okara instead of flour dry matter in the wafer cup recipe. At the same time, the wettability of finished products is reduced by 5–6%, which will positively affect the consumer properties of finished products when stored with ice cream. In experimental products, the amount of carbohydrates decreases by 4.9 - 5.9%, cellulose - increases by 78 and 87 times, calcium - by 1.5-1.8 times, the energy value decreases by 1.4 - 1.7%, and the biological value increases by 2.9 - 3.4% compared with control sample.

Multilayer fi lm structures based on solid solutions of the CdS–ZnS system with variable thickness concentrations of cadmium and zinc were obtained by the pyrolysis of aerosol solutions of thiocarbamide coordination compounds. Their transmission spectra, the photoluminescence spectra, and the temperature dependence of the photocurrent are studied. It is shown that the photocurrent at the wavelength of the exciting light (380 nm) is not monotonically dependent on the temperature, which is associated with the competition of carrier excitation and recombination processes The purpose of this work is to study the crystal structure and properties of multilayer structures synthesized by pyrolysis of aerosol on the basis of solid solutions of the CdS–ZnS system with successive changes in the ratios of the atomic fractions of cadmium and zinc ions It is established that the highest photoluminescence intensity is observed for layers precipitated from TCS [M (N2H4CS) 2CI2]. For all the samples, the luminescence bands broadened. The results of X-ray phase analysis showed that all the layers deposited in the multilayer structure have a wurtzite modifi cation, are polycrystalline, and have a pronounced crystallization direction. The multilayer structures synthesized from [M(N2H4CS)2Br2] have a steady-state current value comparable to the values for individual CdS synthesized under similar conditions. Optical studies have shown that the transmission spectra do not refl ect the intrinsic absorption edge for each deposited layer. The value of the bandgap width for CdS → ZnS samples is slightly increased when compared with individual CdS. Multilayer ZnS → CdS samples synthesized from chloride coordination compounds have a greater optical width compared to samples from bromide TCS.
