This study is devoted to the development of a technology for the production of mono-and diglycerides based on local raw materials and the assessment of its efficiency. Mono-and diglycerides are important surfactants widely used in the food, pharmaceutical and cosmetic industries. The main goal of the study is to create the possibility of producing import-substituting products and rational use of local fat and oil raw materials. In the process, the composition of vegetable oils was analyzed, and their esterification and transesterification reactions with glycerin were studied. The main factors affecting the process were determined - temperature, type of catalyst, reaction time and ratio of components. The physicochemical parameters of the obtained mono- and diglycerides, including acid number, solubility and emulsification properties, were evaluated. The research results showed that it is possible to obtain high-quality and competitive mono- and diglycerides based on local raw materials. The proposed technology is economically efficient and serves to reduce production costs. This scientific work is of great importance in the development of the food industry, expanding the use of local resources and creating new functional additives.
