The objects of study were the following: cream as a raw material before and after pasteurization, as well as pasteurized cream seeded with testing cultures of various types of spoilage microorganisms. The samples were stored at temperature conditions of 30 ± 1 °C, 10 ± 1 °C, and 4 ± 2 °C. To evaluate the quality and storage capacity of cream used as a raw material, its microbiological and physicochemical indicators were determined by standardized methods: bacterial number, titratable acidity, indicators of oxidative spoilage of the fat phase. Organoleptic characteristics were evaluated in terms of taste, consistency and appearance. Research results have shown that the greatest microbiological risks during storage of cream used as a raw material are associated with lactococci, coliform bacteria and yeast. Microbiological risks caused by seeding of cream with thermophilic streptococcus, spore bacteria of the genus Bacillus and spore anaerobic microorganisms of the genus Clostridium are less significant, which is associated with the lack of development and metabolism of these groups of microorganisms at storage temperatures of 10 ± 1 °C and 4 ± 2 °C. At the same time, the reason for the rejection of cream contaminated with these testing cultures, at a storage temperature of 4 ± 2 °C, is primarily a decrease in organoleptic indicators, and at a temperature of 10 ± 1 °C — an excess in bacterial number.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлены результаты исследований по изучению влияния различных групп микроорганизмов: БГКП, молочнокислых микроорганизмов, дрожжей, споровых бактерий на качество и хранимоспособность сливок-сырья для маслоделия. В качестве объектов исследования служили: сливки-сырье до и после пастеризации, а также сливки пастеризованные, контаминированные тест-культурами различных видов микроорганизмов порчи. Хранение образцов осуществляли при температурных режимах 30 ± 1 °C, 10 ± 1 °C и 4 ± 2 °C. Для оценки качества и хранимоспособности сливок-сырья стандартизованными методами определяли их микробиологические и физико-химические показатели: бактериальную обсемененность, титруемую кислотность, показатели окислительной порчи жировой фазы. Органолептические показатели оценивали по вкусу, консистенции и внешнему виду. Результаты исследований показали, что наибольшие микробиологические риски при хранении сырых сливок связаны с лактококками, БГКП и дрожжами. Микробиологические риски, обусловленные обсеменением сливок термофильным стрептококком, споровыми бактериями рода Bacillus и споровыми анаэробными микроорганизмами рода Clostridium, менее значимы, что связано с отсутствием развития и метаболизма данных групп микроорганизмов при температурах хранения 10 ± 1 °C и 4 ± 2 °C. При этом основанием для забраковки сливок, контаминированных данными тест-культурами, при температуре хранения 4 ± 2 °C в первую очередь является снижение органолептических показателей, а при температуре 10 ± 1 °C — превышение по бактериальной обсемененности.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сливки-сырье</kwd><kwd>масло</kwd><kwd>хранимоспособность</kwd><kwd>тест-культура</kwd><kwd>БГКП</kwd><kwd>лактококки</kwd><kwd>термофильный стрептококк</kwd><kwd>дрожжи</kwd><kwd>споровые микроорганизмы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cream as raw material</kwd><kwd>butter</kwd><kwd>storage capacity</kwd><kwd>testing culture</kwd><kwd>coliform bacteria</kwd><kwd>lactococci</kwd><kwd>thermophilic streptococcus</kwd><kwd>yeast</kwd><kwd>spore microorganisms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках выполнения исследований по государственному заданию № 0585–2019–0012 Федерального научного центра пищевых систем им.
