It’s shown that at рН&gt;IEP of the lactoglobulin the interaction occurs between negatively charged chains of LM-pectin and positively charged patches of polypeptide chains. The biopolymers ratio had no significant effect on the initial pH of soluble complex formation (pHc); addition of sodium chloride decreased pHc and pK0 of complexes, which linked to electrostatic nature of complex formation between LM-pectin and whey proteins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комплексообразование</kwd><kwd>НМ-пектин</kwd><kwd>концентрат белков молочной сыворотки</kwd><kwd>потенциометрическое титрование</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">Dickinson E.
