Установлено, что при подкислении сусла до рН 4,5 создаются более благоприятные условия для жизнедеятельности дрожжей, сокращается продолжительность брожения, увеличивается выход спирта, улучшаются показатели бражки, снижается вероятность инфицирования бражки посторонней микрофлорой, содержание альдегидов уменьшается на 10-15% , высших спиртов - на 8-10%, глицерина - на 15-20%, а также наблюдается небольшое снижение содержания кислот и эфиров.</p></abstract><trans-abstract xml:lang="en"><p>The influence of pH on the accumulation of by-products of fermentation in the mash was studied. Found that the acidification of musts to pH 4.5 created more favorable conditions for the yeast, reducing the duration of fermentation, increasing the amount of alcohol, improving indicators of mash, decreases the likelihood of infection mash, aldehyde content was reduced by 10-15%, higher alcohol – by 8-10%, 15-20% glycerol, and a slight reduction of acids and esters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спиртовое брожение</kwd><kwd>глицерин</kwd><kwd>кислоты</kwd><kwd>альдегиды</kwd><kwd>эфиры</kwd><kwd>высшие спирты</kwd><kwd>рН сусла</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">Яровенко, В.Л.
