Для проведения экспериментов из картофельного крахмала готовили крахмальную суспензию, модифицированную ферментными препаратами амилолитического действия: Дистицим БА-Т и Дистицим АГ. Обработку крахмальной суспензии для получения резистентного крахмала проводили при температуре -18°C и в среде жидкого азота при -196°C. Обработку при высоких температурах проводили при температуре 120°C в течение 15, 30, 45, 60 мин. Устойчивость резистентного крахмала определяли по количеству редуцирующих веществ, полученных после повторной обработки крахмальной суспензии ферментными препаратами на средах с низкими и высокими значениями рН, оценивали по росту лактобактерий. В результате было установлено, что наибольшей устойчивостью обладает резистентных крахмал, полученный после автоклавирования крахмальной суспензии при 120°C в течение 15 мин. На питательной среде с добавлением данного образца наблюдался наибольший рост микроорганизмов, в 2 раза выше, чем на питательной среде без добавления крахмальной суспензии. Важно учитывать полученный вывод в случаях, когда необходимо включать резистентный крахмал в рецептуры функциональных продуктов питания. Особенно это актуально для приготовления ферментированных продуктов на основе зерна или сока, где редуцирующие вещества играют важную роль на стадиях приготовления. В то же время, резистентный крахмал может использоваться в качестве пребиотика, обеспечивая питательную среду для микрофлоры кишечника. Таким образом, результаты исследования могут быть применены для разработки новых и улучшения существующих функциональных продуктов питания с учетом их пищевой ценности и влияния на микробиоту кишечника</p></abstract><trans-abstract xml:lang="en"><p>The influence of low- and high-temperature treatments on the production of resistant starch was investigated. For the experiments, a starch suspension, modified with amylolytic enzyme preparations: Distizym BA-T and Distizym AG, was prepared from potato starch. Treatment of the starch suspension to obtain resistant starch was conducted at -18°C and in liquid nitrogen at -196°C. High-temperature treatment was carried out at 120°C for 15, 30, 45, and 60 minutes. The resistance of resistant starch was determined by the amount of reducing substances obtained after repeated treatment of the starch suspension with enzyme preparations at low and high pH values, assessed by the growth of lactobacilli. As a result, it was found that the greatest stability was exhibited by resistant starch obtained after autoclaving the starch suspension at 120°C for 15 minutes. On the nutrient medium supplemented with this sample, the highest growth of microorganisms was observed, which was 2 times higher than on the nutrient medium without the addition of starch suspension. It is important to consider this finding when including resistant starch in the formulations of functional food products. This is especially true for the preparation of fermented products based on grain or juice, where reducing substances play an important role in the preparation stages. Additionally, resistant starch can serve as a prebiotic, providing a nutrient-rich environment for intestinal microflora. Thus, the results of the study can be used to develop new and improve existing functional food products, taking into account their nutritional value and effect on the intestinal microbiota.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>модификация крахмала</kwd><kwd>резистентный крахмал</kwd><kwd>низкотемпературная обработка</kwd><kwd>высокотемпературная обработка</kwd><kwd>обработка ферментными препаратами</kwd><kwd>«искусственный желудок»</kwd><kwd>«искусственный кишечник»</kwd><kwd>молочнокислые бактерии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>starch modification</kwd><kwd>resistant starch</kwd><kwd>low-temperature treatment</kwd><kwd>high-temperature treatment</kwd><kwd>treatment with enzyme preparations</kwd><kwd>“artificial stomach”</kwd><kwd>“artificial intestine”</kwd><kwd>lactic acid bacteria</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">Ших Е.В., Махова А.А., Астаповский А.А., Перков А.В.
