In emergencies, including increased stress, injuries, diseases, traumas, and during the recovery period, the compliance of nutrition with the special metabolic body needs is critical. Considering this, the use of foods for special medical purposes, particularly enteral nutrition, has become quite widespread in modern dietary practice. The purpose of this study was to develop the suitable macronutrient composition of dry soluble gerodietetic products for enteral nutrition, which would meet consumer preferences with its organoleptic properties. For this, the study found that specialists in nutritional support for the emergency needs of representatives of older age groups recommend the ratio of protein, fats, and carbohydrate components in the total energy value (%) within 17-21/28-34/45-55, respectively. For people with type 2 diabetes, these values were 26-51/31-35/14-43. Based on this, the corresponding mass ratios of macronutrients were determined. This provided the base for dry soluble products for enteral nutrition development. Based on their organoleptic evaluation in the ready-to-consume liquid state, the most optimum were defined: 24.5/14.5/61.0 wt. % for representatives of older age groups without any metabolic complications, 61.0/16.0/23.0 wt. % for patients with type 2 diabetes. These products were selected for further use and enrichment with a specially designed functional composition in the further products development. The study also developed mathematical models to describe the relationship between the complex organoleptic quality indicators of macronutrient compositions for enteral nutrition and their protein, fat, and carbohydrate content. The practical value of this study lies in improving the methodological principles of dry soluble gerodietetic products for enteral nutrition development and in the possibility of using the developed mathematical models to optimise their macronutrient composition
