A number of authors have developed a recipe for donuts using bird cherry flour and orange peel. It is known from literary sources that the use of bird cherry flour and orange peel has a positive effect on the quality of flour bakery and confectionery products. At the first stage of research, on the basis of organoleptic and physicochemical parameters, the optimal dosage of bird cherry flour was selected, which amounted to 30% of the total volume of wheat flour in the recipe. At the second stage, the donut recipe, using 30% bird cherry flour, served as a control option, and samples with the addition of 3.5,7.9% orange peel were used as prototypes. It was found that when 7% orange peel was applied, the donuts acquired a golden color, pleasant taste and aroma compared to the control sample. A further increase in the amount of orange zest led to a deterioration in the quality indicators of the baked product. At the final stage, we developed a donut recipe with a content of 30% bird cherry flour and 7% orange peel. It has been established that this ratio of ingredients improves both organoleptic and physicochemical characteristics. Thanks to the addition of orange peel, the content increases: vitamin C by 0.14 mg / 100g, carotenoids by 0.14 mg / 100g in products, as well as microelements: potassium - by 231.17, magnesium - by 25.89, iron - by 0.22, phosphorus - by 21.81. The acidity of the finished products increases by 0.029 degrees due to the presence of organic acids in the orange peel. The acidity of the dough also increases with an increase in the dosage of bird cherry flour due to the fact that the herbal supplement contains more organic acids (malic, citric, ascorbic) than wheat flour. The acidity increases from 2 to 13%, but is within the acceptable range. The energy and nutritional value of the finished products of the pilot sample increased by 14.84 kcal in comparison with the control sample.
