Purpose of the research: study of crotonaldehyde formation conditions in the process of starch-containing raw materials fermentation and adjustment of technological modes of raw material preparation and its fermentation in order to minimize the formation of this impurity Object of research: the process of obtaining ethyl alcohol from starch-containing raw materials. Subject of research: wort from starch-containing raw materials, yeast, technology of ethanol from starch-containing raw materials, by-products of alcoholic fermentation, mature wort, ethyl alcohol, crotonaldehyde. An information analysis of crotonaldehyde formation’ dependence on the technological conditions of starch-containing raw materials` fermentation, as well as an analysis of the factors of the technological process that affect the amount of crotonaldehyde formation in the distillate was carried out. The influence of individual technological stages of ethyl alcohol fermentation on the formation of crotonaldehyde was determined. Based on obtained data, methodological recommendations were developed to minimize the amount of crotonaldehyde formation during the production of ethyl alcohol for the needs of the food and pharmaceutical industries. Keywords: starch-containing raw materials, fermentation by-products, yeast, wort, ethyl alcohol, crotonaldehyde
