   <abstract xml:lang="ru">
    <p>При получении концентрированных кисломолочных продуктов важной технологической задачей является управление процессом отделения сыворотки, определяющим консистенцию, влагоудерживающую способность и выход продукта. Для кефира как продукта смешанного брожения представляет интерес мягкое концентрирование методом самопрессования, однако влияние характеристик лавсановых мешков на интенсивность процесса изучено недостаточно. Работа была направлена на установление рациональных параметров самопрессования кефира в лавсановых мешках по показателям отделения сыворотки. Объектом исследования являлся кефир, выработанный с использованием кефирных грибков. На первом этапе изучали отделение сыворотки в конических мешках из лавсана плотностью 110, 114, 125, 130 и 145 г/м2. На втором этапе в цилиндрических мешках исследовали только ткани плотностью 114 и 125 г/м2, отобранные по результатам первого эксперимента. Количество отделившейся сыворотки определяли гравиметрическим методом. Дополнительно оценивали содержание сухих веществ и органолептические характеристики сцеженного кефира. Установлено, что плотность лавсановой ткани существенно влияет на ход самопрессования кефира. Лавсан плотностью 110 г/м2 признан технологически непригодным вследствие интенсивного просачивания кефира через поры ткани. Наиболее перспективными по результатам первого этапа оказались ткани плотностью 114 и 125 г/м2. Дополнительная оценка цилиндрических мешков позволила уточнить выбор конструкции, наиболее рациональным вариантом признан конический мешок из лавсана плотностью 114 г/м2. Полученные результаты могут быть использованы при разработке и совершенствовании технологии производства концентрированного кефира с регулируемыми показателями консистенции и отделения сыворотки.</p>

    <p>Controlled whey separation, or syneresis, is a key technological task in the production of strained and concentrated fermented dairy products because it determines texture, water-holding capacity, and product yield. Kefir is a mixed-fermentation dairy product that requires gentle concentration by self-pressing. However, the effects of filtering fabric parameters and polyester bag design on process efficiency remain insufficiently studied. The aim of the work was to determine the most rational parameters of polyester bags for kefir self-pressing based on whey separation, total solids content, and sensory properties of the strained product. It featured kefir produced with kefir grains. At the first stage, the syneresis was evaluated in conical polyester bags with fabric densities of 110, 114, 125, 130, and 145 g/m2. The second stage focused on the 114 and 125 g/m2 samples. The amount of separated whey was determined gravimetrically. Other parameters included total solids content and sensory properties of strained kefir. Polyester fabric density was found to affect both the course of self-pressing and the properties of the final product. The 110 g/m2 fabric proved to be technologically unsuitable because kefir leaked through the pores. Based on the overall set of indicators, a conical bag made of 114 g/m2 polyester was identified as the most rational option. These findings can be applied to develop and improve technologies for strained and concentrated fermented dairy products with controlled texture and syneresis properties.</p>
