Polievoda Yurii – candidate of technical sciences, associate professor of the department of technological processes and equipment for processing and food production, Vinnytsia National Agrarian University: Vinnitsia, st. Sonyachna 3, VNAU, 21008, e-mail: vinyura36@gmail.com.
The article presents information on surfactants. Given their complete classification, methods of obtaining glaringly surface-active substances (surfactants). A list of surfactants concerning natural and synthetic substances is presented.
Proven to be the most promising (cheap) production method of surface-active substances is transesterification oils and fats as the most simple in technological implementation.
Presents the results of a study of the effect of surfactants on the protective, flavouring and structural properties of foods. Identified a number of features in the character of interaction of components in the system of food and processing industry – surface-active substance.
Methods of obtaining distillation emulsifiers of glycerol fatty acids and transesterification of triglycerides with glycerol are investigated. The main physico-mechanical properties of glycerine all grades. There is a need to obtain surfactants synthetically.
Analyzed the technology of production of new method ethanols emulsifiers of dietary fats by distillation of low molecular weight acids with ethyl alcohol and subsequent transesterification dietary fat.
Describes the technologically-line of obtaining these emulsifiers T – 1 and T – F. Details are given broad temperature regimes of the process.
Describes the manufacturing process of the monoglycerides and their derivatives, obtained by separation of the mixture of reaction products of glycerol, unreacted, digald and products of side reactions by centrifugation and molecular distillation.
The technological schemes of obtaining all kinds of monoglycerides and the process of molecular distillation as a method of fractional distillation of high molecular weight liquids are considered.

Publisher Vinnytsia National Agrarian University
In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
