   <abstract xml:lang="ru">
    <p>Цель исследования заключается в выявлении рациональных параметров мембранной фильтрации для эффективного разделения молочных белков и получения концентрированного казеинового продукта, необходимого для нормализации состава смеси по соотношению белковых фракций. Это, в свою очередь, позволит улучшить функциональные характеристики вытяжных сыров, производимых на основе данной смеси. Актуальность работы обусловлена отсутствием в России комплексного изучения применения мицеллярного казеина в технологии вытяжных сыров. Это исследование направлено на восполнение данного пробела и разработку рекомендаций для повышения функциональных свойств конечного продукта. Для проведения экспериментов была использована мембранная установка, разработанная инженерами ООО «УМК» (г. Узловая, Российская Федерация) и оснащенная рулонными полимерными мембранами с размером пор 0,05 мкм. В ходе исследования изучалось влияние четырех факторов на процесс разделения молочных белков. Результаты исследования позволили обосновать следующие рациональные параметры: температура пастеризации обезжиренного молока не должна превышать 68 °C; температура подачи обезжиренного молока на микрофильтрационную установку должна быть в диапазоне 45–50 °C; степень разбавления обезжиренного молока влияет на содержание казеина в ретентате микрофильтрации; входящее давление обезжиренного молока не должно превышать 0,10 МПа. На основе полученных данных была разработана рациональная последовательность технологических операций для нормализации смеси по соотношению белковых фракций: сепарирование цельного молока, пастеризация обезжиренного молока, диафильтрация, микрофильтрация, наведение смеси, пастеризация. Дальнейшие исследования будут направлены на определение оптимального соотношения белковых фракций для производства вытяжных сыров с заданными функциональными свойствами.</p>

    <p>Stretch-curd cheese is prepared using the pasta filata technique. It needs protein separation to obtain a concentrated casein product that stabilizes the ratio of protein fractions in the mix. This process requires optimal membrane filtration parameters to yield stretch-curd cheese with good functional properties. This research is the first of its kind in domestic food science to provide a comprehensive study of micellar casein in stretch-curd cheese production. The article contains some recommendations for improving the functional properties of the final product. The test involved a membrane installation (Dairy Plant Uzlovskiy Molochniy Kombinat LLC, Uzlovaya, Russia) with rolled polymer membranes with a pore size of 0.05 μm. The research tested the effect of four factors on protein separation. The resulting optimal parameters (for skimmed milk) were as follows: pasteurization temperature ≤ 68 °C; temperature supply to the microfilter – 45-50 °C; incoming pressure ≤ 0.10 MPa. The casein content in the microfiltration retentate depended on the dilution degree. The rational technological scheme to obtain the optimal ratio of protein fractions included separation of whole milk, pasteurization of skimmed milk, diafiltration, and microfiltration. Further research will determine the optimal ratio of protein fractions for the production of stretch-curd cheese with targeted functional properties.</p>
