Holub (содержание витаминов, минеральных и др. веществ, благоприятно влияющих на организм человека), изучен процесс экстрагирования кипрея узколистого из сухого растительного сырья водным раствором. Исследование концентрации кипрея узколистного в водном растворе с использованием рефрактометра показало, что до 20 мин. настаивания количество сухих веществ в экстракте растет, после 20 мин. настаивания концентрация сухих веществ остается постоянной. Таким образом, установлено оптимальное время настаивания - 20 мин. В результате исследования ускоренным методом подъемной силы прессованных дрожжей с использованием водного раствора и экстракта кипрея узколистного установили, что с внесением растительной добавки подъемная сила дрожжей уменьшилась по сравнению с контролем на 10,5%. Это свидетельствует о том, что продукты кипрея узколистного благоприятно воздействуют на дрожжевые клетки. Исследованы дрожжевые суспензии из воды и дрожжей и водного экстракта кипрея узколистого и дрожжей. По истечении 60 мин. термостатирования и последующего микроскопирования, с определением концентрации дрожжевых клеток с помощью счетной камеры Горяева, позволило установить, что концентрация дрожжевых клеток в суспензии с экстрактом кипрея узколистного превышает концентрацию в контрольной суспензии почти в 1,5 раза. Такое явление вызвано стимулирующим действием отдельных компонентов, входящих в состав кипрея узколистного (сахарами, витаминами, минеральными веществами и другими компонентами), являющихся дополнительным источником энергии. Предлагается к применению экстракт кипрея узколистого как сырья, используемого в приготовлении хлебобулочных изделий профилактического назначения.</p></abstract><trans-abstract xml:lang="en"><p>This article presents the results of the study of the beneficial properties of narrow-leaved rosebay willowherb (Chamerion angusti folium (L.) Holub) (the contents of vitamins, minerals and other substances which positively affect the human body). The process of extraction of a narrow-leaved spray from a dry plant raw material with an aqueous solution was looked at. The investigation of the concentration of narrow-leaved rosebay willowherb in an aqueous solution using a refractometer revealed that a 20 min. infusion shows the constant growth of dry matter in the extract. However after the 20 min. period the concentration of solids stays constant. Therefore, the optimum infusion time was set to 20 min. As a result of the study, the accelerated method of lifting the pressed yeast using an aqueous solution and a lemon grass extract revealed that, with the addition of the plant additive, the lifting power of the yeast decreased by 10.5%.This indicates that the products of narrow-leaved rosebay willowherb favorably affect yeast cells. Yeast suspensions from water and yeast and aqueous extract of narrow-leaved rosebay willowherb and yeast spray have been studied. After 60 min. of thermostating and further microscope study, with the determination of the concentration of yeast cells with the help of Goryaev's chamber, allowed to establish that the concentration of yeast cells in suspension with the extract of narrow-leaved rosebay willowherb exceeds the concentration in the control suspension by almost 1.5 times. This phenomenon is caused by the stimulating effect of the individual components that make up the narrow-leaved rosebay willowherb (sugars, vitamins, minerals and other components), which are an additional source of energy. It is proposed to use the spray extract of the narrow-leaved rosebay willowherb as a raw material in the preparation of bakery products for preventive purposes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кипрей узколистый</kwd><kwd>экстрагирование</kwd><kwd>хлебопекарные дрожжи</kwd><kwd>влияние экстракта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>narrow-leaved cyprus</kwd><kwd>extraction</kwd><kwd>baking yeast</kwd><kwd>extract effect</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">Заикина М.А., Хворостова А.А., Сушко В., Барвенова И.
