Flour confectionery semi-finished products, which are delicious and have a high nutritional value, are always popular with people of all ages. Cake is one of the favorites and most common flour confectionery products for consumers all over the world. Wheat flour is one of the main ingredients used for the preparation of biscuit semi-finished products, along with sugar, egg, preservatives, flavorings, etc. Partial or complete replacement of wheat flour is always desirable to make the product more nutritious. Replacing wheat flour with other different flour improves the functional and nutritional properties of Brownie semi-finished products. The technological parameters and the recipe for the production of semi-finished Brownie products related to low-calorie products have been developed. Wheat flour was replaced with rice, corn and flaxseed flour, the ratios of which were derived as a result of experimental studies of the recipe. Butter was replaced with soft cottage cheese, which reduced the caloric content of the product. Yogurt has been replaced with a fruit supplement (in the form of frozen apple pomace) to increase nutritional value. Instead of sugar, the sweetener "Prebiosweet" is used, which includes the sweetener erythritol, lactulose, sweetener stevia extract. In contrast to the classical production technology in the developed one: the number of technological operations is reduced; the operation of whipping the egg mixture is excluded. Mixing of ingredients was carried out in two stages: at the first stage, all dry components were mixed; at the second stage, all liquid components were mixed. Then the liquid and dry mixtures were mixed to a homogeneous consistency. The duration of mixing was reduced to 2-3 minutes. and it was carried out at low speeds of the kneading machine. The Brownie semi-finished product was baked at a temperature of 175 ℃ for 60 minutes. The addition of rice, corn and flax flour will expand the diet of people who monitor their health, apple squeezes.

The program for the development of sustainable food systems is aimed primarily at providing the population with affordable, safe and nutritious foods. Improvement in quality can be achieved by gradually reformulating food products, increasing their nutritional value through the use of healthy ingredients. The most preferred methods for assessing the organoleptic properties of gluten-free biscuits have been identified. The article identifies the most preferred methods for assessing the organoleptic properties of gluten-free biscuits. A descriptor-profile method was used to evaluate the organoleptic properties for the developed biscuit recipes. Recipes of flour confectionery products - gluten-free biscuits have been developed: sample No. 1 contains oat flour, corn flour, corn starch and chickpea flour mixed with mineral sparkling water and sweetener; sample No. 2 contains oat flour, corn, sweetener and chickpea flour mixed with sparkling mineral water. The descriptors that most fully evaluate the flavour and aromatic properties (wheat, oat, corn, chickpea, egg) of classic and gluten-free biscuits have been identified. A scale of evaluation of the complex indicator of organoleptic properties of gluten-free biscuits has been formed, taking into account the weight of the criteria. An expert assessment of organoleptic quality indicators (shape, cross-sectional view, surface, taste and smell) was carried out taking into account the weight of the criteria. The developed samples for these indicators were compared with a biscuit sample developed according to the classical recipe. The sample with the highest total value in terms of organoleptic quality indicators in relative units has been identified. As a result of the tasting, using the descriptor-profile method, the taste characteristics of gluten-free biscuits were evaluated. To visualise the taste characteristics of the studied samples, a profilogram was constructed. It was revealed that the sample of biscuit No. 2 is more balanced in terms of taste and aromatic properties.

Consumption of fermented milk products containing healthy substances is an effective means of strengthening the protective functions of the human body. Development of the new product technology is based on a well-founded method of introduction of plant components forming their composition and properties. The purpose of this work is to study the method of adding a mixture of aronia and hawthorn powders, the effect on organoleptic indicators and individual physicochemical properties of yogurt. During the work, a set of generally accepted standard research methods was used. The subjects of the study are samples of yogurt produced by a thermostat method, but differing in the step of introducing an enrichment additive. Digestion was performed using a dry bacterial starter for "vivo" brand yogurt. Based on the results of the study, the stage and method of adding a plant additive to the milk mixture are selected. The optimal dose for adding aronia and hawthorn powders to the milk mixture was 5%. It has been found that the addition of the additive before fermentation leads to a deterioration in appearance and consistency (whey peel off), and when a mixture of aronia and hawthorn powders is introduced at the fermentation stage, it contributes to an improvement in organoleptic indices of goat's milk-based yogurt. According to physical and chemical indicators, the developed sample according to the proposed technology meets the requirements set by TR TS 021/2011, TR TS 033/2013 and GOST 31981.
