Целью настоящего исследования являлось повышение стабильности и увеличение срока годности мягкого рассольного сыра за счёт комплексного применения экстракта хмеля на стадии производства и последующей выдержки продукта в рассоле, обогащённом молекулярным водородом (H₂). Основная идея работы заключалась в изучении синергетического антиоксидантного эффекта, возникающего при совместном использовании этих двух природных факторов. Научная значимость работы состоит в обосновании нового подхода к стабилизации мягких рассольных сыров с использованием природных антиоксидантов, а практическая значимость – совершенствование технологии, позволяющей существенно продлить срок хранения продукта без применения синтетических добавок. Методология исследования основывалась на проведении контролируемого экспериментального моделирования с формированием сравнительных групп образцов мягкого рассольного сыра (контроль и опытные варианты), включающих применение экстракта хмеля и рассола, обогащённого молекулярным водородом. Оценивались физико-химические (окислительно восстановительный потенциал, активность воды, pH), микробиологические и органолептические показатели качества сыра в процессе хранения. Установлено, что применение водород-обогащённого рассола приводит к снижению окислительно-восстановительного потенциала до низких значений по сравнению с контрольным образцом, стабилизации активности воды на уровне 0,638–0,640 (в контроле 0,781–0,888) и поддержанию pH в узком диапазоне 4,96–5,08 (в контроле 5,30–5,77), что свидетельствует о формировании более стабильной среды и повышении устойчивости продукта при хранении. Микробиологические показатели соответствуют нормативным требованиям: патогенная микрофлора не обнаружена, общее количество мезофильных аэробных и факультативно-анаэробных микроорганизмов (КМАФАнМ) составляет 1,0–1,2 log КОЕ/г. Полученные результаты указывают на антиоксидантный эффект, способствующий повышению стабильности продукта и потенциальному увеличению срока хранения без ухудшения его органолептических и функциональных характеристик. Проведённое исследование вносит вклад в развитие технологий производства функциональных и экологически безопасных молочных продуктов с использованием природных стабилизирующих систем. Полученные результаты имеют практическое значение для молочной промышленности и могут быть использованы для повышения стабильности качества и увеличения срока хранения мягких рассольных сыров.</p></abstract><trans-abstract xml:lang="en"><p>The high moisture content and short shelf life of soft brined cheeses create a serious problem of rapid spoilage, necessitating the search for effective natural stabilizers to preserve product quality and safety. The aim of this study was to improve stability and extend the shelf life of soft brined cheese through the combined application of hop extract during production and subsequent storage in brine enriched with molecular hydrogen (H₂). The main idea was to investigate the synergistic antioxidant effect arising from the combined use of these two natural factors. The scientific significance lies in substantiating a new approach to stabilizing soft brined cheeses using natural antioxidants, while the practical significance lies in improving the technology to extend shelf life without synthetic additives. The methodology was based on controlled experimental modeling with comparative groups of cheese samples (control and experimental variants), including hop extract and hydrogen-enriched brine. Physicochemical (oxidation-reduction potential, water activity, pH), microbiological, and organoleptic indicators were evaluated during storage. It was established that hydrogen-enriched brine reduces oxidation-reduction potential compared to the control, stabilizes water activity at 0.638–0.640 (control: 0.781–0.888), and maintains pH within 4.96–5.08 (control: 5.30–5.77), indicating a more stable environment and improved product stability. Microbiological indicators meet regulatory requirements: pathogenic microflora was not detected, and the total count of mesophilic aerobic and facultative anaerobic microorganisms (TAMC) is 1.0–1.2 log CFU/g. The results indicate an antioxidant effect that improves product stability and may extend shelf life without deterioration of organoleptic and functional characteristics. The study contributes to the development of technologies for functional and environmentally safe dairy products using natural stabilizing systems. The results have practical significance for the dairy industry and can be used to improve quality stability and extend the shelf life of soft brined cheeses.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мягкий рассольный сыр</kwd><kwd>экстракт хмеля</kwd><kwd>молекулярный водород</kwd><kwd>антиоксидантные свойства</kwd><kwd>антимикробные свойства</kwd><kwd>водород-обогащённая вода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>soft brined cheese</kwd><kwd>hop extract</kwd><kwd>molecular hydrogen</kwd><kwd>antioxidant properties</kwd><kwd>antimicrobial properties</kwd><kwd>hydrogen-enriched water</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research was funded by the Committee of Science of the Ministry of Science and Higher Education of the Republic of Kazakhstan (grant No. BR24992914).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alwazeer D., Tan K., Örs B.
