Исследуемую масличную культуру применяют в различных сферах, как в пищевых целях, животноводстве, так и в медицине. Рассмотрена характеристика масла расторопши пятнистой. Известно, что семена расторопши пятнистой могут содержать 35 % жиров. Масло получено методом холодного прессования. В качестве объекта исследования выбрано масло семян сорта расторопши пятнистой. С помощью экспериментального экструдера получено масло при режимах: кольцевой зазор зеерной камеры – 1.25 мм, частота вращения шнека – 190 об/мин, температура прессования – 353 К. Проведено сравнительное исследование жирнокислотного состава компонентов масла расторопши пятнистой с литературными источниками. Использован метод газожидкостной хроматографии на приборе «Хромотэк 5000» для определения состава компонентов по методике ГОСТ 31665-2012. Произведен расчет по компонентам масла расторопши пятнистой, на основании которых получены хроматограммы по количеству жирных кислот. Установлено, что характеристики исследуемого образца сопоставимы с литературными данными, но имеют и отличия, так как обнаружены другие жирные кислоты в составе масла. В результате газохроматографического анализа выявлено 24 жирные кислоты. Определено следующее соотношение жирных кислот: линолевой – 53 %, олеиновой – 26 %, пальмитиновой – 8 %, стеариновой (5 %), арахиновой (3 %) и бегеновой (2 %). Исследуемый образец содержит в своем составе насыщенные и ненасыщенные жирные кислоты. Из результатов анализа витаминного состава следует, что в масле расторопши присутствуют витамины А, Е и К и незначительные следы β-каротина, которые являются ценным источником для профилактического питания.</p></abstract><trans-abstract xml:lang="en"><p>Milk thistle seeds are a unique source of biologically active substances. The oilseed crop studied is used in various fields, both for food purposes, animal husbandry and in medicine. The characteristics of milk thistle oil were considered in the work. Milk thistle seeds are known to contain 35% vegetable oil (seed fat). The oil was obtained with cold pressing. Milk thistle seed oil was chosen as the object of study. Using an experimental extruder, the oil was obtained under the following modes: the annular gap of the grain chamber - 1.25 mm, the screw rotation speed - 190 rpm, the pressing temperature - 353 K. A comparative study of the fatty acid composition of milk thistle oil components with literary sources was carried out. Gas-liquid chromatography on a Chromotek 5000 device was used to determine the composition of the components according to the GOST 31665-2012 method. The calculation for the components of milk thistle oil  on the basis of which the chromatograms were obtained for the amount of fatty acids was made. It was found out that the characteristics of the test sample are comparable with the literature data, but they also have differences, since other fatty acids were found in the oil. 24 fatty acids were identified by gas chromatographic analysis. The following ratio of fatty acids was determined: linoleic - 53%, oleic - 26%, palmitic - 8%, stearic (5%), arachidic (3%) and behenic (2%). The sample under study contains saturated and unsaturated fatty acids. According to the results of the vitamin composition analysis  milk thistle oil contains vitamins A, E and K and minor β-carotene traces which are a valuable source for diet and preventive nutrition.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жирнокислотный состав</kwd><kwd>масло расторопши</kwd><kwd>витамины</kwd><kwd>холодное прессование</kwd><kwd>расторопша пятнистой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fatty acid composition</kwd><kwd>milk thistle oil</kwd><kwd>vitamins</kwd><kwd>cold pressing</kwd><kwd>milk thistle</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">El-haak M.A., Atta B.M., Abd Rabo F.F.
