The results of the influence of the dry powder of the fruits of the Aronia on consumer properties of biscuits, in which wheat flour of the highest grade was replaced with oat flour and, in turn, part of the oat flour - 5, 10 and 15% of fruit powder and cocoa powder are presented. Introduction to the recipe of cocoa powder was due to the fact that the Aroniapowder had a dark color, which turned into grey-green in the baked product, therefore affecting the organoleptic properties of baked biscuit, making it unattractive. This was confirmed experimentally during baking samples of biscuits (sample No. 1). Therefore, to eliminate these drawbacks, cocoa powder was introduced into the recipe in a 1: 1 ratio with Aronia. With an increase in the proportion of applied fruit powder of Aronia, the mass amount of moisture decreased, which can be explained by a decrease in the amount of oat flour used (due to its replacement by fruit powder). By its nature, oatflour contains a large amount of dietary fiber, which has a water-holding capacity, therefore, with a decrease in the amount of oat flout in products, their moisture content decreases. The porosity of the finished product is not affected by the added ingredients, nevertheless, this figure is lower than that of biscuits baked from wheat flour of the highest grade (about 75-80%). Alkalinity in all samples of biscuits was 0.3 degrees. In general, the developed model samples of biscuits with the addition of wild fruit and berry raw materials turned out to be of pretty good quality. According to the results of the analysis of organoleptic and physicochemical parameters for the introduction into mass production, it is possible to recommend samples of biscuits with the addition of 10% of Aronia powder. When establishing expiration dates, it was found that the process of staling proceeds in the samples rather slowly, and the recommended expiration dates for the finished product are 96 hours.

When developing products for healthy and functional nutrition, much attention is currently paid to domestic raw materials of natural origin: fruit, vegetables, cereals and their processed products. In our region, one of these types of raw materials is apple. Apples are a source of nutrients for the human body: vitamins, minerals, organic acids, dietary fiber and pectin. They are the raw material for a large number of fruit and berry products, fillings for flour confectionery products, juice drinks, kissels, etc. During the production of these products, the so-called «secondary raw materials» remain, which are formed as a result of grinding, peeling, squeezing, grating, pressing and other technological operations. The study investigated the effect of addition of apple pomace in dried, crushed to a powdery state, and thawed (after deep freezing) form on the fermentation activity of yeast and the technology of wheat bread production with the addition of buckwheat flour. It has been established that the quality of the finished bread depends on the type of additive: fresh-frozen apple pomace improves the porosity and taste of bread to a greater extent.

This paper presents the results of studying the effect of dry-leaved Chamerion angustifolium (L.) Holub dry powder on quality indicators of wheat bread, in which part of the highest-grade wheat flour was replaced by 3, 5 and 10% of powder. The study showed that the addition of narrow-leaved powder in different amounts (3, 5 and 10% by weight of wheat flour) at the stage of cooking, the dough has a different impact on the quality indicators of the products. With the increase in the amount of the infusion of narrow-leaved powder, the organoleptic and physico-chemical indicators change: the color of the product changes from dark golden to dark brown, the presence of the additive increases in taste and smell, but the products have the correct form, without explosions and cracks, elastic, very soft crumb, with a thin-walled and uniform porosity. With an increase in the amount of the added additive, the porosity decreases, but it does not reach the lower limit of the standard. Acidity and humidity increase, which negatively affects the quality and reduced shelf life of the finished product. Therefore, it is proposed to use dry powder of narrow-leaved fireweed in the amounts of not more than 3% by weight of the flour. Studies have shown that during storage at the bakery product with a 3% additive of dry leaf powder for 72 hours, the total crumb strain is reduced by 32 units. AP-4/2 penetrometer, while in the control sample - by 44 units. Thus, the process of staling bread with the addition of narrow-leaved fireweed powder is slower than that of the control sample, and the recommended shelf life of the finished product is 72 hours.

The influence of secondary apple raw materials (apple pomace powder and frozen apple pomace) on the organoleptic (shape, surface, color, level of baking and mixing, porosity, taste, odor) and physicochemical quality indicators (moisture, acidity and porosity) of wheat bread was studied in the work. The traditional wheat bread recipe in which a part of the premium wheat baking flour was replaced by 5.7% buckwheat flour and 8.6% apple pomace powder, respectively for bread with the addition of apple pomace powder, was taken as a basis. Replacement of a part of the premium wheat bakery flour, respectively, with 6.7% buckwheat flour and 10% fresh frozen apple pomace was made in the second bread sample with the addition of frozen apple pomace, while the amount of water was reduced. The study of the quality indicators of baked bread samples was carried out with expert and organoleptic methods. A five-point scale for bread quality assessing in which each indicator was assigned a maximum number of points - 5, was developed for organoleptic assessment. According to the results of the study of organoleptic quality indicators of the developed samples of wheat bread, enriched with secondary apple raw materials, wuth a point scale, it was found that they exceeded the control sample. At the same time, the sample with fresh frozen apple pomace turned out to be the best, gaining 38.2 points out of 40 possible. It had a regular rounded shape with evenly distributed impregnations of flavoring; pleasant taste and smell characteristic of the products of this name; uniform light brown color; uniform porosity, without voids and seals, without lumps and traces of impurities. A sample of bread with apple pomace powder yielded 1.4 points to it, gaining 36.8 points in all respects. The developed samples of wheat bread enriched with apple raw materials (apple pomace powder and frozen apple pomace) meet the requirements of GOST 31805-2018 in terms of physicochemical indicators
