An assessment of the carbohydrate-amylase and lipid complexes of the three variants of multicomponent bran showed that the ratio of amylose and amylopectin in the starch of three-component bran is almost the same, however, in lentil-flax bran, the proportion of amylose is 1.6 times higher than in the first two variants. The specific activity of amylases in three-component bran is about 2 times higher than in lentil-flax bran. In addition, the latter are characterized by a higher content of reducing sugars and fiber. The molecular weight of amylases isolated from three-component bran, according to gel chromatography, was: α-amylase — 40,000 Da; β-amylase — 60,000 Da. It has been established that the addition of flax seeds to the grinding mixture significantly increases the fat content in bran 6.4; 6.0 and 12.9%. The fatty acid composition of the studied bristles is characterized by the predominance of unsaturated fatty acids. At the same time, the ratio of essential acids — linoleic acid (ɷ‑6) to α-linolenic acid (ɷ‑3) in favor of the most deficient α-linolenic acid — was typical for lentil-flax bran and amounted to 1:4.2. The activity of alkaline lipases, which exhibit their effect at pH 8.0 (mainly cereal lipases), and acid lipases (mainly oilseed lipases) with an optimum of action at pH 4.7 in three-component bran samples are approximately the same, and lentil-flax bran is characterized by a high specific acid lipase activity, which is approximately 4.2 times higher than the activity of acid lipases of three-component bran. The data obtained, along with data on the characteristics of the protein-proteinase complex of the studied types of bran, will be used in the development of methods for enzymatic modification (deep processing) and in the preparation of components for the creation of new food products with increased nutritional and biological value.</p></abstract><trans-abstract xml:lang="ru"><p>Поликомпонентные отруби, полученные при совместном размоле зерносмеси из зерновых (пшеница), бобовых (чечевица) и масличных (лен) культур, следует рассматривать как ценное вторичное сырье, использование которого для глубокой переработки позволит получать различные пищевые и кормовые ингредиенты. Оценка углеводно-амилазного и липидного комплексов трех вариантов поликомпонентных отрубей показала, что соотношение амилозы и амилопектина в крахмале трехкомпонентных отрубей практически одинаково, однако в чечевично-льняных отрубях доля амилозы в 1,6 раза выше, чем в первых двух вариантах. Удельная активность амилаз трехкомпонентных отрубей примерно в 2 раза выше, чем в чечевично-льняных отрубях. Кроме того, последние характеризуются более высоким содержанием восстанавливающих сахаров и клетчатки. Молекулярная масса амилаз, выделенных из трехкомпонентных отрубей, по данным гель-хроматографии составила: α-амилаза — 40 000 Да; β-амилаза — 60 000 Да. Установлено, что добавление семян льна в помольную смесь значительно увеличивает содержание жира в отрубях 6,4; 6,0 и 12,9%. Жирнокислотный состав исследуемых отрубей характеризуется преобладанием ненасыщенных жирных кислот. При этом соотношение эссенциальных кислот — линолевой кислоты (ɷ-6) к α-линоленовой кислоте (ɷ-3) в пользу наиболее дефицитной α-линоленовой кислоты — было характерно для чечевично-льняных отрубей и составило 1:4,2. Активность щелочных липаз, проявляющих свое действие при рН 8,0 (преимущественно зерновые липазы), и кислых липаз (преимущественно липазы масличных культур) с оптимумом действия при рН 4,7 в образцах трехкомпонентных отрубей примерно одинаковая, а чечевично-льняные отруби характеризуются высокой удельной активностью кислой липазы, которая примерно в 4,2 раза превосходит активность кислых липаз трехкомпонентных отрубей. Полученные данные, наряду с данными по особенностям белково-протеиназного комплекса исследуемых видов отрубей, будут использованы при разработке способов ферментативной модификации (глубокая переработка) и при получении компонентов для создания новых пищевых продуктов с повышенной пищевой и биологической ценностью.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пшеница</kwd><kwd>чечевица</kwd><kwd>лен</kwd><kwd>поликомпонентные отруби</kwd><kwd>углеводно-амилазный и липидный комплексы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wheat</kwd><kwd>lentil</kwd><kwd>flax</kwd><kwd>polycomponent bran</kwd><kwd>carbohydrate-amylase and lipid complexes</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках выполнения исследований по государственному заданию № FGUS-2022-0006 Федерального научного центра пищевых систем им.
