Установлено, что протеолиз трипсином (фермент-субстратное соотношение 1 : 40) при температуре 37 °С и pH 8,0 приводит к образованию 81,2 ± 5,5 % пептидов с молекулярной массой менее 3,0 кДа, а при гидролизе белков нейтральной протеазой (фермент-субстратное соотношение 1 : 20) в тех же условиях образуется 86,6 ± 4,7 % низкомолекулярных пептидных фракций. Показано, что последовательное применение трипсина и нейтральной протеазы позволяет получить в среднем 94,9 % коротких пептидов по сравнению с совместным внесением (91,3 ± 1,1 % низкомолекулярных пептидов). Применение только одного фермента обеспечивает получение частичных гидролизатов, которые могут быть использованы в рецептурах функциональных продуктов питания с пониженной аллергенностью, в то время как последовательное и совместное внесение трипсина и нейтральной протеазы приводит к образованию глубоких гидролизатов, которые считаются идеальными ингредиентами в создании гипоаллергенных пищевых продуктов.</p></abstract><trans-abstract xml:lang="en"><p>A comparative analysis of the efficiency of milk protein hydrolysis by trypsin and neutral protease using different methods of their addition was conducted. It was found that proteolysis by trypsin (enzyme-substrate ratio 1 : 40) at a temperature 37 °C and pH 8.0 leads to the formation of 81.2 ± 5.5 % of peptides with molecular mass less than 3.0 kDa, while protein hydrolysis by neutral protease (enzyme-substrate ratio 1 : 20) under the same conditions produces 86.6 ± 4.7 % of low molecular weight peptide fractions. It was shown that sequential application of trypsin and neutral protease allows obtaining, on average, 94.9 % of short peptides in comparison with the joint addition (91.3 ± 1.1 % of low molecular weight peptides). The application of the single enzyme provides the production of partial hydrolysates that can be used in the formulation of functional foods with reduced allergenicity, while the sequential and joint addition of trypsin and neutral protease generates extensive hydrolysates, which are considered optimal ingredients in the creation of hypoallergenic food products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ферментативный катализ</kwd><kwd>трипсин</kwd><kwd>нейтральная протеаза</kwd><kwd>белки молока</kwd><kwd>низкомолекулярные пептиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>enzymatic catalysis</kwd><kwd>trypsin</kwd><kwd>neutral protease</kwd><kwd>milk proteins</kwd><kwd>low molecular weight peptides</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">Белковый гидролизат как источник биоактивных пептидов в пищевой продукции диабетического питания / О.
