Food products are most often falsified by imparting them some of the most typical features, for example appearance, upon  the overall  worsening or losing the other most  significant properties of nutritional value, including safety. Market analysis shows that there is a tendency of replacing natural roe with imitated roe by its selling  in metal and glass jars with indication of the address of the Far Eastern producer. It has been established that the protein  content is not higher than one percent upon  imitated roe production using  modern technologies. To establish product authenticity, a methodology for measuring the protein mass fraction in grained salmonid roe by the Kjeldahl method was developed. The metrological characteristic of the developed methodology in three concentration ranges is presented. The used values  can serve for identification of claimed properties with the  specified  indicators of accuracy, trueness, repeatability and reproducibility. In addition to the methodology, product organoleptic indicators are proposed, including assessment of appearance, consistency, taste, odor, as well as specific features of the cooking test  that can serve as distinctive features and are taken into consideration in identification of grained salmonid roe.</p></abstract><trans-abstract xml:lang="ru"><p>В статье рассмотрена проблема фальсификации пищевой рыбной продукции, которая беспокоит производителей и потребителей во всем  мире. Фальсификация пищевых продуктов чаще  всего осуществляется путем  придания продуктам отдельных наиболее типичных признаков — например, внешнего вида  при общем ухудшении или утрате  остальных наиболее значимых свойств пищевой ценности, в том числе безопасности. Анализ  рынка показал, что наблюдается тенденция подмены натуральной икры  имитированной  путем  реализации ее в металлических и стеклянных банках  с указанием адреса Дальневосточного производителя. Установлено, что при  производстве имитированной икры  по современным технологиям содержание белка  не превышает одного процента. Для установления подлинности продукции разработана методика измерений массовой доли  белка  в зернистой икре  лососевых рыб методом Кьельдаля. Представлена метрологическая характеристика разработанной методики в трех  диапазонах концентраций. Использованные значения могут  служить  для  идентификации  заявленных свойств с установленными показателями точности, правильности, повторяемости и воспроизводимости. В дополнении к методике предложены органолептические показатели продукции, включающие оценку внешнего вида,  консистенции, вкуса, запаха, а также  особенности пробы  на варку, которые могут служить в качестве отличительных признаков и учитываться при проведении идентификации икры  зернистой лососевых видов  рыб.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>имитированная продукция</kwd><kwd>пищевая ценность</kwd><kwd>белок</kwd><kwd>органолептический анализ</kwd><kwd>тест на варку</kwd></kwd-group><kwd-group xml:lang="en"><kwd>imitated products</kwd><kwd>nutritional value</kwd><kwd>protein</kwd><kwd>organoleptic analysis</kwd><kwd>cooking test</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы  выражают благодарность сотрудникам лаборатории метрологии влагометрии и  стандартных  образцов  (241) УНИИМ — филиал ФГУП «ВНИИМ им.
