Abstract
The prospects for the use of a plant raw material – stevia as a natural sweetener for obtaining sweet extracts have been substantiated. Literary research has been conducted on the expediency of carrying out preparatory operations of stevia-raw material in order to intensify mass exchange processes during extraction; their necessity has been theoretically justified.
 A number of studies have been conducted with the aim of intensifying the process of extracting the dry mass of stevia leaves. Preliminary preparation of stevia was carried out – crushing (using a laboratory crusher – A1-DM2R) and subsequent sieving to the average size of the leaf fraction – 3.9±0.1 mm.
 It is proposed to use whey from the production of sour milk cheese to obtain sweet extracts of stevia for their further use in the food industry.
 It has been established, that the highest efficiency of the extraction process of the prepared dry stevia leaf mass is achieved with a hydromodule – 1:15. Carrying out the process under these conditions allows to achieve the highest degree of extraction of extractive substances – 29.9.
 The results of the experimental studies, obtained and presented in the article, can be used to carry out further physicochemical analyzes of the quality of the obtained stevia extracts and the possibility of combining them with a milk base to obtain a dietary range of food products
