OPTIMIZATION OF RECIPE FOR BAKERY PRODUCTSWITH LOW-MOISTURE CONTENTFOR REDUCING THE GLYCEMIC INDEX

Abstract

The modern concept of recipe development and improvement has to be based on fundamental knowledge about the chemical composition of ingredients as well as mechanisms of their assimilation. Glycemic index of food products, including bakery products, becomes important in the aspect of the spread of a metabolic syndrome that is a complex of various metabolic disorders that lead to the development of atherosclerosis and cardiovascular disease. The article shows the possibility of creating a recipe for sweet baked goods with low moisture content and reduced glycemic index due to using the buckwheat flour, dry wheat gluten, oat bran and aqueous extract of stevia. We have used modern methods of setting up the experiment and processing their results. The influence of these ingredients on the glycemic index has been characterized. The efficiency of using Stevia as natural sweeteners, has shown, for developing approaches to reduce the energy value and the glycemic index of bakery products. The coefficients of the regression model were given as a result; it has helped to find out the patterns of influence of both selected components and their dosage on the glycemic index, energy value and sensory characteristics of the product. The article presents the results of multicriteria optimization, which can be used to create recipe compositions using selected ingredients using of modern software Design-Expert 11. The amount of buckwheat flour was in range 5–20%, dry wheat gluten – 5–15%, oat bran – 2–6% of the total number of dry ingredients in the formulation. A rational ratio of the main ingredients has been found to provide an optimal ratio of the factors "low glycemic index - excellent taste". The glycemic index of developed baked goods with low moisture content was 57–58.This article has shown the possibility of using an integrated approach in forming the recipe of low-moisture bakery products with a reduced glycemic index.
