Abstract
The consumers’ preferences for various types of vegetable oils have been revealed: 70 % of the Russian population prefer sunflower oil. With the help of a sociological survey, it was found that respondents mostly prefer refined vegetable oil – 68 %. The analysis of the accuracy and stability of the technological process for the production and purification of vegetable oil was carried out. The numerical characteristics of the distribution law of the controlled parameters were estimated. The reasons of oil defects based on claims for the period of 2017-2020 were analyzed, and the analysis of the process stability was carried out. The Ishikawa diagram made it possible to establish the causes of arising problems in terms of the color index which are the applied sorbent and the conditions for oil clarification. It is recommended to use adsorbents in the form of nanomaterials in food industry when clarifying sunflower oil.
