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.

Currently, a promising direction in baking is the introduction of microelements such as iodine into the recipe of bread and bakery products. The presence of iodine in the formation of the thyroid hormone determines its biological role. This trace element is the only one known that is involved in the construction of hormones. The development of endemic goiter is caused by a lack of iodine in the body. The influence of apple iodine-pectin extract on physical and chemical quality indicators (moisture, acidity and porosity) of rye-wheat bread was studied. During the manufacturing process of a prototype rye-wheat bread, a standard recipe was used with the replacement of part of the water with apple iodine pectin extract obtained using sodium bicarbonate and adding iodine. The addition of this additive to the rye-wheat bread recipe improves organoleptic quality indicators. In terms of physical and chemical characteristics, bread with the addition of apple iodine-pectin extract meets the requirements of regulatory documents and standards. In order to justify the introduction of apple iodine-pectin extract into the rye-wheat bread recipe, the content of phosphorus and iron in bread samples was analysed using a spectrophotometer. A sample bread containing iodcasein from a local manufacturer was used as a benchmark for the purpose of this review. The iodine content was determined by titration of iodine released during the interaction of potassium iodate and potassium iodide. Analysis of the chemical composition showed that the introduction of apple iodine-pectin extract into the formulation contributes to an increase in the content of minerals, macro- and microelements in bread. On comparison of the samples, the test sample containing apple iodine pectin extract proved to stay fresh for longer than a control sample for 12-24 hours.
