The authors note that the difference in the methodological approach to the determination of GI in vitro leads to obtaining results that are difficult to compare. A modified method for determining the GI for glucose is proposed, which is based on the method for determining the glycemic index for glucose, which makes it possible to assess the digestibility of various ingredients in products in terms of sugar load, and to calculate the glycemic index for glucose formed in the process of "digestion” of the test product in vitro. The modified technique provides for the use of digestive enzyme preparations: Acedin-pepsin and Panzinorm to provide a deeper "digestion” in vitro, providing a deep degree of hydrolysis of the main macronutrients in in vitro model experiments. The conditions for carrying out enzymatic hydrolysis reactions (temperature, pH, reaction duration) were selected experimentally. The studies carried out to determine the GI in vitro, according to the proposed method, showed comparable values, which indicates the possibility of using this method for the determination of GI in vitro. The results obtained should be considered as indicative, since the authors adhere to the position that the true value of the GI index can only be determined by blood analysis. But in this case, the value of GI is influenced by many factors, including the individual characteristics of the human organism.</p></abstract><trans-abstract xml:lang="ru"><p>Проведен анализ методов определения гликемического индекса (ГИ) пищевых продуктов in vivo и in vitro. Авторы отмечают что разница в методическом подходе к определению ГИ in vitro приводит к получению, трудно сопоставимых результатов. Предложена модифицированная методика определения ГИ in vitro в основе которой лежит метод определения гликемического индекса по глюкозе, который позволяет оценить с точки зрения сахарной нагрузки усвояемость в продуктах различных ингредиентов, и рассчитать гликемический индекс по глюкозе, образовавшейся в процессе «переваривания» исследуемого продукта in vitro. Модифицированная методика предусматривает использование для обеспечения более глубокого «переваривания» in vitro пищеварительных ферментных препаратов: Ацедин-пепсин и Панзинорм, обеспечивающих в модельных экспериментах in vitro высокую степень гидролиза основных макронутриентов. Условия проведения реакций ферментативного гидролиза (температура, рН, продолжительность реакции) были подобраны экспериментально. Проведенные исследования по определению ГИ in vitro, согласно предложенной методике показали сопоставимые значения, что свидетельствует о возможности использования данной методики для определения ГИ in vitro. Однако, полученные результаты следует рассматривать как ориентировочные, поскольку авторы придерживаются позиции, что истинное значение показателя ГИ может быть определено лишь по анализу крови, но и в этом случае на значение ГИ влияет множество факторов, в том числе и индивидуальные особенности организма человека.</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>пшеничная мука</kwd><kwd>мультизерновая смесь</kwd><kwd>индексы перевариваемости</kwd><kwd>гликемический индекс</kwd><kwd>способы определения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>wheat flour</kwd><kwd>multi-grain mixture</kwd><kwd>digestion indices</kwd><kwd>glycemic index</kwd><kwd>determination methods</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">Барановский, А.Ю.
