Theoretical and practical aspects of development of biscuits with a modified carbohydrate profile for patients with type 2 diabetes

Abstract

The purpose of this research was to develop formulation and technology of flour confectionery products in the form of biscuits with a modified carbohydrate profile, a study of physico-chemical and structural-mechanical properties. The оbjects of this research were: basic food matrix, are the prototype of the designed product without modification of the carbohydrate profile prepared by the classic recipe and traditional technologies; model samples of cookies with a modified carbohydrate profile; the experimental sample cookie with a modified carbohydrate profile and optimized physic-chemical, structural-mechanical and organoleptic indicators. Determination of physic-chemical and organoleptic characteristics of biscuits was carried out by standard methods. The water activity was determined on the analyzer using a cooled mirror dew point sensor, structural-mechanical properties – on texturename with conical and cylindrical nozzles, imitating the processes of breakage and bite, describing the hardness, brittleness, breakage, and other properties of a food product. The modification of the carbohydrate profile of biscuit, consisting in the replacement of wheat flour traditionally used in the recipe of flour confectionery products, by the composition containing oat, barley and buckwheat flour, and in the exclusion of sugar and the introduction of ingredients that do not cause hyperglycemic effect: maltitol as a sweetener and beta-glucans. The technological scheme of production of new kinds of cookies has been developed, the parameters of the production process have been worked out, physical-chemical, structural-mechanical and organoleptic properties of a new type of cookie have been optimized. Analysis of the chemical composition of the cookies showed that 100 g contains 9.3 g of protein, 17.0 g of fat and 44.5 g of carbohydrates, including 42.4 g of starch, and 2.1 g mono- and disaccharides, 2.2 g dietary fiber, 20 g maltitol; caloric value of 420 kcal/1760 kJ. In accordance with the developed technology an experimental batch of cookies with a modified carbohydrate profile has been produced to evaluate its impact on postprandial glycemia in patients with type 2 diabetes.
