Determination of the content of organic acids in the chemical composition of buckbuckthorn oil, obtained from regional raw materials

Abstract

The purpose of the work is to determine the content of organic acids in the chemical composition of sea buckthorn oil obtained from regional raw materials and to establish the influence of sea buckthorn oil production technology on the content of biologically active substances. Sea buckthorn is a unique source product for enriching food products with biologically active substances that play a diverse, important role in the vital activity of the body. It has been proven that the content of organic acids and vitamin C is the main variable in the chemical components of sea buckthorn, the phytochemical and nutritional composition of whose berries differs significantly depending on the species, climatic and growing conditions, and the technology of obtaining sea buckthorn oil. This attracts attention from the standpoint of the need to study sea buckthorn, which grows in regional territories. It was established that sea buckthorn oil obtained from the juice contains: organic acids 154.1–167.5 mg%, vitamin C 168-214 mg%. Sea buckthorn oil extracted with refined sunflower oil contains: organic acids 234.5–388.6 mg%, vitamin C 189–243 mg%. The effect of the technology of obtaining sea buckthorn oil from regional raw materials on the content of biologically active substances, such as organic acids, vitamin C, was determined. Based on the results of research, the advantages of oil obtained by the technology of extraction with refined sunflower oil were determined. Such oil contains a larger amount of ascorbic acid and free organic acids. When analyzing the results of research on oil and dry raw materials collected in the Kherson region, it was established that in the case of organic acids, in particular vitamin C, the indicator of quantitative content is affected not only by the production technology, but also by the biological variety of sea buckthorn. It is advisable to intensively continue scientific work on the research of substances that are responsible for the specific biological activity of sea buckthorn oil.
