Применение защитных заквасочных культур не требует дополнительного оборудования или изменения технологических параметров. Защитная культура вносится вместе с основной закваской и работает по традиционному принципу ферментации, а также путем конкурентного исключения, т.е. занимая пространство и снижая возможность для роста дрожжей, плесеней и БГКП. Проведено две выработки молокосодержащего продукта – первая с применением защитной культуры (экспериментальный образец), вторая – без использования защитной культуры (контрольный образец). Продукты заложены на хранение в течение 40 суток при температуре 4±2 °С. В контрольном образце на 30 сутки наблюдали рост дрожжей, ухудшение органолептических показателей, повышение титруемой кислотности, на 40 сутки – продукт считали испорченным. В экспериментальном образце органолептические, физикохимические и микробиологические показатели при хранении находились в пределах нормы. Определен срок годности молокосодержащего продукта с заменителем молочного жира, произведенного по технологии сметаны, с применение защитной культуры с учетом коэффициента запаса 30 суток. Установлено увеличение срока годности последнего на 30 % по сравнению с контрольным образцом.</p></abstract><trans-abstract xml:lang="en"><p>The authors proposed a milk-containing product with a substitute for milk fat, produced according to the technology of sour cream using a protective culture in order to prolong the shelf life. The use of protective starter cultures does not require additional equipment or changes in technological parameters. The protective culture is introduced along with the main sourdough and works according to the traditional principle of fermentation, as well as through competitive exclusion, i.e. taking up space and reducing the possibility for the growth of yeast, molds and BGKP. Two developments of a milk-containing product were carried out - the first using a protective culture (experimental sample), the second without using a protective culture (control sample). The products are stored for 40 days at a temperature of 4 ± 2 °C. In the control sample, on day 30, yeast growth, deterioration in organoleptic indices, increase in titratable acidity were observed, on day 40, the product was considered spoiled. In the experimental sample, organoleptic, physicochemical and microbiological parameters during storage were within normal limits. The shelf life of a milk-containing product with a milk fat substitute produced using the technology of sour cream is determined using a protective culture taking into account a safety factor of 30 days. An increase in the shelf life of the latter by 30% was established in comparison with the control sample.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молокосодержащий продукт</kwd><kwd>заменитель молочного жира</kwd><kwd>сметана</kwd><kwd>защитная культура</kwd></kwd-group><kwd-group xml:lang="en"><kwd>milk-containing product</kwd><kwd>milk fat replacer</kwd><kwd>sour cream</kwd><kwd>protective culture</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">Shi J.
