   <abstract xml:lang="ru">
    <p>Проблемы переработки молочной сыворотки, несмотря на многообразие существующих технологий и продуктов, до настоящего времени остаются актуальными, особенно с учетом высокой ценности сывороточных белков. Одним из наиболее востребованных направлений является создание функциональных напитков, при производстве которых используется процесс ферментативного гидролиза белков молочной сыворотки. Целью данной работы является изучение и совершенствование технологических параметров ферментативного гидролиза белков молочной сыворотки. Предложены биотехнологические принципы получения напитков, включающие электрохимическую активацию и ферментативный гидролиз белков молочной сыворотки. Изучено влияние электрохимической активации на динамику изменения рН молочной сыворотки, степень и продолжительность ферментативного гидролиза. В образцах гидролизованной сыворотки исследованы пептидные профили и число свободных аминогрупп с использованием системы Experion Pro260. Применение электрохимической активации позволяет интенсифицировать процесс гидролиза белков молочной сыворотки и повышает эффективность действия гидролитических ферментов. Проведена оптимизация процесса ферментативного гидролиза белков молочной сыворотки, обработанной электрохимической активацией, и определены оптимальные параметры процесса гидролиза: рН – 7,25, продолжительность ферментации – 6 ч, температура – 38–40 °С при использовании ферментов с активностью 25 000 и 36 000 единиц на мл. Анализ количественного и качественного состава спортивных напитков подтвердил обогащение аминокислотного состава.</p>

    <p>Whey proteins are valuable components of functional drinks. Whey processing involves a wide range of technologies and products, e.g., whey protein enzymatic hydrolysis. The authors developed a new set of technological parameters of enzymatic hydrolysis. The research yielded new biotechnological principles for functional whey drinks based on electrochemical activation and enzymatic hydrolysis. Electrochemical activation affected the pH, degree, and time of enzymatic hydrolysis. The peptide profiles and the number of free amino groups in the samples of hydrolysed whey were studied using the Experion Pro260 system. Electrochemical activation intensified the hydrolysis and increased the effectiveness of hydrolytic enzymes. The optimal parameters of whey hydrolysis were as follows: pH 7.25, fermentation time – 6 h, temperature – 38-40 °C, enzyme activity – 25,000 units/mL and 36,000 units/mL. The resulting functional drinks were fortified with amino acids.</p>
