Йогурт с пониженным содержанием жира характеризуется неудовлетворительными реологическими и текстурными свойствами, что обусловлено удалением жирового компонента. Резистентный крахмал, выделенный из красной чечевицы, —многофункциональный ингредиент, способен улучшить структуру и стабильность молочных продуктов, а также оказать благотворное влияние на функционирование организма за счет пребиотических свойств.</p></sec><sec><title>Цель</title><p>Цель. Изучить влияние резистентного крахмала, полученного из красной чечевицы, на реологические свойства низкожирового йогурта и определить его оптимальную концентрацию для улучшения текстуры продукта.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В образцы низкожирового йогурта вводили резистентный крахмал, выделенный из красной чечевицы, в концентрации от 0,5 до 2,0 %. Реологические показатели йогурта (динамическую вязкость, коэффициент синерезиса и водоудерживающую способность) определяли с использованием реометра. Степень синерезиса в йогурте оценивали путем анализа когезионной прочности и устойчивости к водоотделению. Объем отделившейся сыворотки измеряли в процессе хранения продукта при постоянной температуре и рассчитывали процент отделения сыворотки.</p></sec><sec><title>Результаты</title><p>Результаты. Добавление в состав низкожирового йогурта резистентного крахмала привело к изменениям реологических свойств продукта, степень выраженности которых зависела от концентрации введенной добавки. Полученные данные показали, что добавление резистентного крахмала повышает водоудерживающую способность йогурта и снижает синерезис. Оптимальное влияние на вязкость и, соответственно, на консистенцию йогурта наблюдалось при концентрации резистентного крахмала 1,0–1,5 %. Увеличение дозировки до 2,0 % обеспечивало наибольшую водоудерживающую способность, однако сопровождалось снижением вязкости. Кроме того, резистентный крахмал оказывал положительное влияние на текстурные показатели (твердость и когезионность), приближая консистенцию продукта к йогуртам с более высоким содержанием жира.</p></sec><sec><title>Выводы</title><p>Выводы. Резистентный крахмал, полученный из красной чечевицы, демонстрирует высокий прикладной потенциал в качестве функционального ингредиента для улучшения свойств низкожирового йогурта. Его использование способствует повышению вязкости, укреплению гелевой структуры, а также улучшает устойчивость продукта к синерезису. Данный компонент может рассматриваться как перспективный для разработки функциональных молочных продуктов с пониженным содержанием жира. При этом необходимо оптимизировать его концентрацию во избежание возможного негативного влияния на органолептические характеристики продуктов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Low-fat yogurt is often characterized by reduced textural and rheological properties due to the removal of fat. Resistant starch derived from red lentils is a multifunctional ingredient capable of improving the structure and stability of dairy products, while also providing additional health benefits owing to its prebiotic properties.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the effect of adding resistant starch RS3 isolated from red lentils on the rheological, textural, and syneretic properties of fat-free yogurt and to determine its optimal concentration for improving product quality.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. Samples of  low-fat yogurt were prepared with the addition of resistant starch at concentrations of 0.5–2.0 %. Rheological parameters (viscosity, syneresis index, and water-holding capacity) were determined using a rheometer. Syneretic stability was assessed by evaluating cohesive stability and resistance to water separation. The volume of separated whey was measured after a specified storage period at a constant temperature, and the percentage of separation was calculated.</p></sec><sec><title>Results</title><p>Results. The addition of resistant starch RS3 resulted in pronounced concentration-dependent changes in yogurt properties. The data showed that RS3 incorporation enhanced the water-holding capacity of yogurt and reduced whey separation. The optimal effect on viscosity and sensory-related properties was observed at RS3 concentrations of 1–1.5 %, whereas the addition of 2 % provided the highest water-holding capacity but could be accompanied by a reduction in viscosity. Furthermore, RS3 supplementation influenced textural parameters (hardness and cohesiveness), bringing the consistency characteristics closer to those of yogurts with higher fat content.</p></sec><sec><title>Conclusions</title><p>Conclusions. Resistant starch RS3 obtained from red lentils demonstrates high applied potential as a functional ingredient for improving the properties of fat-free yogurt. Its use contributes to increased viscosity, strengthening of the gel structure, and enhanced resistance to syneresis. This component may be considered promising for the development of functional low-fat dairy products; however, optimization of its concentration is necessary to avoid possible adverse effects on organoleptic characteristics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>резистентный крахмал</kwd><kwd>красная чечевица</kwd><kwd>низкожировой йогурт</kwd><kwd>реологические свойства</kwd><kwd>синерезис</kwd><kwd>текстура.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>resistant starch</kwd><kwd>red lentils</kwd><kwd>low-fat yogurt</kwd><kwd>rheological properties</kwd><kwd>syneresis</kwd><kwd>texture</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">Огнева, О.
