The object of this study was gluten-free flour confectionery. In order to improve the structure of the assortment and create products for specialized purposes, the hypothesis was tested that ultra-high-frequency processing can help reduce the microbiological contamination of raw materials and improve the organoleptic characteristics of finished products. For this purpose, recipes for gluten-free flour confectionery products were developed, making it possible to obtain the best values of the specific volume of finished products – custard semi-finished products and gluten-free cupcake. Based on the implementation of second-order rotatable plans, regression models were built, and the resulting response surfaces were transformed to the canonical form. Based on this, it was established that the rational ratios of the components of the cupcake in the formulation are: 80 % flour from ultra-high-frequency processed chickpea flour, 15 % rice, and 5 % amaranth flour. The ratio of components of the custard semi-finished product from ultra-high-frequency processed chickpea flour and corn flour was approximately 50:50 %. Prototypes of gluten-free flour confectionery products were produced, and the main quality indicators were determined. It was found that when flour from ultra-high-frequency processed chickpeas was introduced into the recipe of a cupcake from rice and amaranth flour, the amount of limiting amino acid lysine increased by 1.08 times compared to unprocessed chickpea flour. In the custard semi-finished product, the amount of the limiting amino acid arginine increased by 1.97 times compared to unprocessed chickpea flour. In general, the biological value of enriched cupcake and custard semi-finished product on average exceeds the control sample by 1.5 times. In terms of safety, the developed gluten-free flour confectionery products meet the requirements of regulatory documentation.
