Comparative evaluation of samples of chocolate butter with sucrose and various doses of stevia sweetener

Abstract

Currently, there is a need to create food products with a reduced content of carbohydrate-fatty components for therapeutic, prophylactic and functional purposes. The development of new products should be based on a reasonable choice of ingredients that form their composition and properties. In the face of an increasing number of people with diabetes, to maintain normal blood sugar levels, complications of the disease can be prevented (reduced) by eliminating sugar and sugar-containing foods from the diet. One of the most promising and relevant areas for the creation of new recipes and technologies for the production of dairy products, incl. chocolate butter is the addition of components that regulate the carbohydrate composition of the finished product to the recipe. The purpose of this work is to study the possibility of using the sweetener stevia (stevioside) to obtain a low-calorie diabetic butter chocolate butter, as well as to develop a formulation and manufacturing technology for the product. The work was carried out at the Federal State Budgetary Educational Institution of Higher Education Nizhny Novgorod State Agricultural Academy. In carrying out the work, a set of generally accepted standard research methods was used. The objects of research are samples of butter made by churning from cream with mdzh. 35-38% according to GOST 32261 with the introduction of components in various ratios: cocoa powder 2.5% (for all samples); stevioside: sample No. 1 - 0.15%, sample No. 2 - 0.30%, sample No. 3 - 0.45%. Control sample: cocoa powder 2.5% and powdered sugar 15.0%. The samples complied with the requirements of GOST 32899. A comparative assessment of the organoleptic characteristics of experimental samples of butter chocolate was carried out, the optimal doses of functional ingredients for enrichment were established: cocoa powder - 2.5%, stevioside 0.3%. The tasters found that experimental samples of chocolate butter had a pleasant sweet taste and aroma, with a mild brown "chocolate" color.
