The development of functional foods with specified beneficial properties is one of the main directions in the problem of maintaining and preserving the health of the population. To solve this problem in the diet include products produced using dietary supplements made from natural ingredients. In addition, the problem of creating food with a certain texture made it possible to isolate thickeners and gelling agents food additives that regulate the consistency and form the structure of the product. The department of technology of meat, dairy products and chemistry of the Bashkir State Agrarian University developed two functional combined products, dairy and vegetable yogurt: 1 using dried horse milk and 2 using dried horse milk and vegetable component, pumpkin seed flour, identified their physicochemical properties and the proposed method for studying structure formation in fermented milk products. The study on the example of yoghurt 1 proved that when lactic acid fermentation proceeds, a decrease in the carbohydrate content of the product leads to an increase in its acidity and this causes a change in the consistency of the product. As a result, a ferment with lactic acid bacteria, producing exopolycarbohydrates, dried mare's milk and a vegetable component from pumpkin flour containing pectins, turned out to be good thickeners and gelling agents. All of the above components of yogurt are natural raw materials, so they can be used as safe food additives in the production technology of fermented milk products. In addition, the introduction of dried mare's milk contributes to the correction of the protein composition of the milk mixture, and the use of pumpkin seed flour in the production of yogurt enhances the beneficial properties of yogurt. This research is very relevant from the point of view of developing useful functional products.

Milk and milk products are in steady demand and included in the daily human diet. This paper describes the technology and the nutritional and biological value of the combined yogurt for dietary nutrition. The pumpkin puree and oat flour are used as functional vegetable ingredients in the yogurt formulation. Developed yogurt contains 2.8% of protein, 2.0% of fat and 15% of carbohydrates. The protein of yogurt consists of all essential and nonessential amino acids with high level of isoleucine (2.27 g/100g), leucine (3.45 g/100g), valine (2.46 g/100g), proline (3.91 g/100g) and glutamic acid (7.30 g/100g). Among fatty acids the larger parts occupies caprylic (27.45%), capric (20.13%) and lauric (20.15%) acids. The yogurt has a sufficient amount of the important vitamins, such as A, E, D, C and B group.
