Increasing the number of chronic non-communicable diseases around the world is a critical social problem in many countries. In this regard, the creation of specialized foods that correct dysfunctions of the human body is a priority direction in science and food industry. Legumes are characterized by a high content of protein, minerals and trace elements, which determines their possible use as the main raw materials for creating specialized foods. The aim of this research was to present a medical, biological and technological justification for the possibility of producing pasta based on composite mixtures of durum wheat semolina and white bean flour as specialized foods with increased protein content and optimal mineral ratio. Material and methods. The objects of the study were grains of durum wheat (grade Krasnokutka-13), whole meal flour from white beans, composite mixtures in various percentages, and pasta from them. The nutritional and biological value of durum wheat semolina and bean flour was determined experimentally, the nutrient profile of the developed composite mixtures - by calculation. The rheological properties of dough from composite mixtures and the cooking properties of pasta made from them were assessed. Results. It has been established that increase in the proportion of white bean flour in composite mixes elevated calcium and protein content, optimized an amino acid profile, the ratio of calcium to phosphorus, significantly reduced the glycemic load. Bean flour introduction into composite mixtures positively affected the rheological properties of the dough and products from it, in particular, on the speed and energy intensity of dough kneading and aging processes of starched polysaccharides, however, lead to a decrease in dry pasta strength. The pasta made from composite mixtures meets the technological requirements for pasta in terms of a number of basic indicators, namely: the volume of dry pasta, the volume of pasta after cooking and the boilability coefficient. Conclusion. The rheological and technological properties of composite mixtures and their nutrient profile make it possible to recommend them for the production of pasta, as specialized foods.
