description: The topic of the final qualification work: "Forecasting the shelf life of vegetable oil on the example of unrefined olive oil." The object of the study are unrefined olive oils. The subject of the study is the prediction of the shelf life of olive oils. The aim of the work is a comparative analysis of the quality of olive oils presented on the Russian market and forecasting their shelf life. The following tasks were solved: the composition and factors that determine the quality and safety of olive oils were studied; the modern assortment and consumer preferences were studied, a comparative analysis of the quality, safety, and biochemical composition of olive oils in the process of thermal oxidation and storage was carried out, the shelf life of olive oil was calculated considering the reserve coefficient. When collecting information, abstract and full-text databases of peer-reviewed scientific literature elibrary, Scopus, WoS, ScienceDirect, ResearchGate, official Internet resources "Techexpert", official websites of electronic trading platforms were used. The research was carried out based on the laboratory of commodity science and examination of consumer goods of the Higher School of Economics and Technology. The work uses standard and generally recognized methods of physical and chemical analysis in commodity science and instrumental methods for studying the biochemical composition. The processing of experimental data and their visualization was carried out using the software (data analysis package) Microsoft Excel. Under the conditions of foreign economic sanctions, unrefined extra virgin olive oil from Europe remains in demand on the Russian consumer market, which, due to parallel imports, is mainly sold after 7-11 months from the date of bottling. It has been found that accelerated aging by exposure to high temperatures is not suitable for predicting the shelf life of unrefined olive oils. The method of regression analysis based on experimental data on quality and safety indicators made it possible to adequately describe the hydrolytic and oxidative processes that occur during storage of unrefined olive oil, which can be used to predict its shelf life, considering the reserve coefficient. The obtained results of the work can be used by manufacturers and wholesalers to determine the shelf life of unrefined olive oils.
