Introduction. Processing of grain raw material with influence on starch or albumens by application of heat treatment creates the variety of functional properties of a product and is perspective in the modern terms vital functions of man. Research methods and methods. The flour obtained from wheat of the Ascanian wheat and from wheat of the soft varieties: Sophia ("sweet wheat"), Blond (soft) and Chornobrova (enriched with micro- and macronutrients) were used in the study. Thermal modification of flour samples was carried out in a convective manner. The control sample for determining the quality indicators is obtained in industrial conditions, extruded wheat flour produced by LLC "AS groups, LTD". Research results. The obtained kinetic dependence shows the gradual loss of moisture standards with different speed which accordingly influences on duration of drying. The moisture content of the drying agent most affects the intensity at the initial stage of the constant drying rate. With an increase in the moisture content of the coolant, the period of constant drying increases and the amount of evaporated moisture increases during this period. With the subsequent removal of moisture from raw materials, the degree of influence of this parameter on the intensity decreases. The nature of the drying curves is the same and the recommended process for obtaining modified flour is the process duration of 300 minutes or 5 hours. It was determined microscopically, that the samples of dried wheat flour have a purpose and are partially destroyed by starch granules and amorphization of biocomposite materials. Based on the data on the kinetics of drying flour samples, the kinetic coefficients and values of the critical moisture content for drying wheat flour were calculated, which is 1.18-1.30 %. It was determined that for the sensorial indicators the obtained samples have indicators characteristic of the varietal characteristics of wheat, from which the flour was taken. In terms of physical and chemical parameters, the modified wheat flour samples are not inferior to the well-known industrial sample of extruded flour. Conclusions. Use of flour, obtained from the wheat with different correlation of amilose and amylopectin, positively influences on a technological process and allows to extend the assortment of modified starch products, and accordingly, food products. Kinetics of the convective drying standards of the flour is investigated. Researches showed that a it is physically modified flour obtained from the different sorts of the soft wheat is not inferior in quality to the extruded wheat flour.

The article considers the issue of improving the quality of flour confectionery products through the use of new technologies and different types of raw materials. There is only one type of wheat flour in the retail network of Ukraine, which is characterized as flour with strong or medium gluten. Scientists of NAAS of Ukraine have selectively developed new varieties of soft-grained wheat, which are used to produce extrusion flour. Taking into account the specific properties of extruded flour from soft wheat, it is advisable to explore the possibility of its use in the technology of confectionery and culinary products, in particular, in the production of biscuit flour products and sauces. Analysis of different types of flour and starch was performed on physicochemical and organoleptic parameters. The quality of the finished products was controlled by organoleptic and physicochemical parameters, among which special attention was paid to the indicators of foaming ability, foam stability, moisture and porosity, and in the case of sauces – viscosity. A comparative analysis of wheat flour and soft-grain wheat flour showed that the content of raw gluten in soft-wheat flour is lower by almost 15 %. The hydration capacity of gluten of soft wheat flour is 29 % higher than that of baking flour. The gluten color of soft wheat flour is yellower than the gluten of baking flour, which will affect the color of semi-finished and finished products. It has been determined that for the production of biscuits, it is best to use soft-wheat flour in a mixture with durum flour. According to organoleptic parameters, the highest score was obtained with a sample with a composition of the composite mixture of 60:40, which is also characterized by higher porosity (5 %) compared to the control sample. In samples of sauces with different structurants, their structural and mechanical properties were investigated by determining the dependence of the effective viscosity on the shear rate. It is established that the obtained model systems using structurants based on flour from soft wheat varieties have high structural and mechanical properties without delamination when reheated. The recipe composition and technological process of production of “Nasoloda” and “Béchamel” sauces and a new sponge cake with the use of soft-grade extruded wheat flour have been developed and substantiated. The main indicators of product quality and safety have been studied. The obtained products meet the requirements for organoleptic, physicochemical and microbiological safety indicators and can be recommended for use.
