Одной из основных проблем сохранения качества растительных масел при хранении является их подверженность окислению, что представляет собой определенную проблему, влияющую, в частности, на срок годности и безопасность. Цель работы заключалась в оценке антиоксидантных свойств сверхкритических экстрактов из бурых водорослей Дальневосточного региона Undaria pinnatifida и Costaria costata и изучении возможности их использования в качестве стабилизирующего агента для сохранения качества и безопасности пищевых растительных масел путем исследования влияния на кинетику окисления и гидролиза. Объектами исследования являлись сверхкритические экстракты морских бурых водорослей Дальневосточного региона U. pinnatifida и C. costata. Использовались современные методы исследования – спектрофотометрический, высокоэффективная жидкостная хроматография. Экспериментально доказано, что сверхкритические экстракты морских бурых водорослей Дальневосточного региона U. pinnatifida и C. costata являются источниками биоактивных веществ, таких как фенольные соединения, каротиноиды, маннит и характеризуются высоким уровнем проявления антиоксидантных свойств в части антирадикальной активности и эффективности, гидроксил-ион связывающей активности, активности поглощения супероксидных радикалов и Fe+2 хелатирующей активности. Фенольные соединения, обуславливающие проявление антиоксидантных свойств представлены 9 веществами. Сверхкритический экстракт морской бурой водоросли C. costata продемонстрировал более высокий уровень проявления антиоксидантных свойств, чем экстракт U. pinnatifida. Сверхкритический экстракт морской бурой водоросли C. costata проявляет более выраженное антиоксидантное влияние на окислительные процессы липидов в растительных маслах в сравнении с экстрактом U. pinnatifida. Стабилизация процессов гидролиза сверхкритическими экстрактами морских бурых водорослей U. pinnatifida и C. costata также является эффективной и позволяет увеличить срок хранения масел на 3 мес. Использование сверхкритических экстрактов морских бурых водорослей Дальневосточного региона U. pinnatifida и C. costata как антиоксидантов для стабилизации окисления липидов эффективно как для рафинированных, так и для нерафинированных растительных масел (соевого и подсолнечного). Полученные уравнения регрессии, описывающие закономерности изменения перекисного и кислотного чисел растительных масел стабилизированных сверхкритическими экстрактами морских бурых водорослей Дальневосточного региона U. pinnatifida и C. costata, характеризуются высокими коэффициентами аппроксимации.

Vegetable oils are susceptible to oxidation during storage, which is a serious problem for shelf-life and food safety. The article describes the antioxidant properties of supercritical extracts from brown algae (Undaria pinnatifida and Costaria costata), Russian Far East. It also explains their prospects as stabilizers that preserve the quality and safety of vegetable oils by affecting the kinetics of oxidation and hydrolysis. The study featured supercritical extracts of marine brown algae Undaria pinnatifida and Costaria costata from Russian Far East. The methods involved spectrophotometry and high-performance liquid chromatography. Supercritical extracts of marine brown algae proved to be reliable sources of bioactive substances, e.g., phenolic compounds, carotenoids, and mannitol. They also possessed antioxidant properties in terms of antiradical activity, hydroxyl ion binding, superoxide radical absorption, and Fe+2 chelating. The experiments revealed nine phenolic compounds responsible for antioxidant properties. The supercritical extract of Costaria costata demonstrated a greater antioxidant effect on lipid oxidation in vegetable oils than Undaria pinnatifida. Both algae proved effective in stabilizing hydrolysis and were able to increase the shelf-life of soy and sunflower oils by three months. Supercritical extracts of Undaria pinnatifida and Costaria costata served as antioxidants to stabilize lipid oxidation in refined and unrefined soy and sunflower oils. The research revealed high approximation coefficients for regression equations describing the patterns of changes in the peroxide and acid numbers of vegetable oils stabilized with supercritical extracts of these marine brown algae.
