Основными процессами, определяющими качество получаемого продукта, являются отделение водо-, соле- и щелочерастворимых белков в сочетании с удалением липидов. Для управления изготовлением продукции в рамках производственногоконтроля предложено использовать оценку динамики накопления белков в экстрагентах и остаточное содержание липидов в готовом коллагене. Проведенный анализ стандартизированных методик определения массовых долей белка и жира, применяемых в пищевой и фармацевтической промышленности, показал теоретическую возможность использования для производственных целей соответственно колориметрического метода с биуретовым реактивом и гравиметрического модифицированного метода Сокслета. Измерение содержания белков позволило обосновать способ определения длительности производственного процесса экстракции при конкретных температурных режимах. Сформулированы необходимое и достаточное условия, служащие граничными факторами при установлении данного параметра. Остаточные количества неколлагеновых белков в полученном продукте рассматриваются как технически трудноудаляемая примесь. Применение широко распространенной методики количественного определения липидов на современном лабораторном оборудовании, пригодном для оснащения производственных лабораторий, в совокупности с проведенным анализом иных доступных стандартизированных методик выявили проблему, связанную с отсутствием приемлемого способа из-за содержания измеряемого компонента в анализируемой матрице ниже достоверных пределов. Ее решением представляется фиксация в технических условиях значения остаточного содержания липидов на уровне двукратного предела повторяемости наиболее точного из доступных методов выполнения измерений.</p></abstract><trans-abstract xml:lang="en"><p>Implementation of a unique method for producing marine placental collagen in the pilot operation conditions required a serious analysis of methods for assessing the parameters of individual technological stages. The main processes determining the quality of the finished product are separation of water-, salt- and alkali-soluble proteins in combination with the removal of lipids. To control the manufacturing process in the framework of in-process monitoring, it has been proposed to use an assessment of the dynamics of protein accumulation in extractants and the residual lipid content in the collagen. The analysis of standardized methods for determining the mass fractions of protein and fat used in food and pharmaceutical industries has shown a theoretical possibility of using the colorimetric method with a biuretic reagent and the gravimetric modified Soxhlet method, respectively, for technological purposes. Measurement of the protein content allowed for justification of a method for determining the duration of the extraction process under specific temperature conditions. The necessary and sufficient conditions are formulated as boundary factors in determining of this parameter. It has been proposed to consider the residual amounts of non-collagen proteins in the finished product as a technically difficult-to-remove impurity. The appliance of a widely used procedure for the quantitative determination of lipids with modern laboratory equipment suitable for production laboratories equipping, together with the analysis of other available standardized procedures, revealed a problem associated with the lack of an acceptable method due to the content of the measured component in the analyzed matrix at a level below reliable results. As a solution, it has been proposed to fix the value of remaining lipid content in product specification at the level of twice the repeatability limit of the most accurate available measurement procedure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>морской плацентарный коллаген</kwd><kwd>параметры технологического процесса</kwd><kwd>количественное определение белков</kwd><kwd>количественное определение жиров</kwd></kwd-group><kwd-group xml:lang="en"><kwd>marine placental collagen</kwd><kwd>parameters of technological process</kwd><kwd>quality determination of proteins</kwd><kwd>quality determination of lipids</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">Способ комплексной переработки икры гидробионтов: пат.
