Development of drinking soursels with enriched protein-carbohydrate composition for potentiation of immune status of the population

Kissel is a traditional dish of the national Russian cuisine. However, a common disadvantage of kissels of traditional composition is the use of carbohydrate substances as a gelling agent, although with their inherent functions of dietary fiber, in the case of using pectin. A pressing problem is the development of food systems of gel-like consistency, an affordable price segment to ensure sustainable consumer demand, enriched with easily digestible protein fractions that have the technological potential for gelation, based on secondary raw materials of the dairy industry. The purpose of the work is to develop recipe-component solutions for drinks of combined composition based on whey and oatmeal for healthy nutrition of the population in conditions of biological risks, a comprehensive assessment of consumer properties of combined drinks. The objects of the study were drinks of jelly-like consistency, prepared according to traditional and developed recipes: "Orange mood" and "Cherry cloud". Oat flour was used as a structure-forming component instead of potato starch, and also instead of part of the granulated sugar in the jelly recipe, in combination with whey. The generalized criterion of the Harrington function for modified drinks is 0.82, which corresponds to the rating of "very good" on the desirability scale. A sensorometric assessment of the aroma of the jelly "Cherry Cloud" was carried out in comparison with the cherry jelly "Naslazhdenie" of the Stailon trademark, manufactured by Preobrazhensky Dairy Plant. It was found that sample 2, compared with sample 1, contains more aliphatic alcohols, esters (acetates), unbound water, volatile acids and less titratable acids, volatile amines. Regardless of the concentrated juice used in the recipes, the kissels received a general tasting score of 8.2 points on a 9point scale, with the following indicators of biological value: coefficient of difference of amino acid score (CDAS) 27.97; biological value (BV) 72.03 %; coefficient of comparable excess ((c) 8.83.
