Целью исследования являлась разработка методики лиофильной сушки для приготовления материала СО состава мяса птицы с аттестованными значениями массовой доли влаги, азота (белка) и жира.</p><p>В качестве исходного материала для приготовления СО использовали мясо птицы: белое (грудка, образец 1) и красное (бедро, образец 2). Процедура приготовления СО включала измельчение, варку, замораживание и лиофильную сушку. Исследование однородности материала выполняли с помощью эталонной установки воздушно-тепловой сушки из состава Государственного первичного эталона ГЭТ 173-2017. Измерение массовой доли азота (белка) осуществляли на Государственном вторичном эталоне ГВЭТ 176-1-2010. Измерения массовой доли жира проводили в соответствии с Государственной первичной референтной методикой измерений.</p><p>Общее время лиофильной сушки для образцов № 1 и № 2 составило 19 и 28 часов соответственно. Общая потеря массы образца № 1 - около 63 %, образца № 2 - около 65 %. Разница в значениях массовой доли влаги материала, высушенного на разных полках сублимационной сушилки, являлась статистически значимой, т. е. материал был неоднородным. Для получения однородного материала проводили дополнительную процедуру гомогенизации: измельчение на лабораторной мельнице, просеивание через сито, тщательное перемешивание и кондиционирование. Аттестованные значения массовой доли влаги, азота, белка, жира для образца № 1 составили 4,5 %, 14,74 %, 92,1 %, 7,9 % соответственно, для образца № 2 - 6,3%, 12,21 %, 76,3 %, 23,8 %. Разработана методика лиофильной сушки для производства СО состава мяса птицы вареного сублимационной сушки. Применение системы лиофильной сушки позволило обеспечить срок годности СО, равный 6 месяцам, при температуре окружающего воздуха (7±3) °C и относительной влажности не более 60 %. По результатам испытаний СО состава мяса птицы вареного сублимационной сушки внесен в реестр утвержденных типов под номером ГСО 11276-2019.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the application of the lyophilization system for preparation of reference materials (RM) for composition of nutritive products samples. The purpose of the research was the development of lyophilization procedure of RM for composition of poultry meat samples preparation with certified values of mass fraction of moisture, nitrogen (protein) and fat.</p><p>The poultry meat of two types was used as the primary material for RM for poultry meat composition preparation -1) white meat (chicken breast); 2) red meat (chicken thigh). The procedure included pounding, boiling, freezing and lyophilisation (syn. freeze drying). The researches for homogeneity were implemented with hot air dryer standard system from the State primary standard GET 173-2017. Measurement of nitrogen (protein) mass fraction was performed on State secondary standard GVET176-1-2010. Measurements of fat mass fraction were performed with accordance to State Primary Reference Measurement Procedure.</p><p>The total time of lyophilization process for samples № 1 and № 2 was 19 and 28 hours, respectively. The total mass loss for sample № 1 was about 63 %, for sample № 2 was about 65 %. The difference in material moisture mass fraction values of materials dried on different trays of freeze dryer was statistically significant, i. e., material was non-homogeneous. To obtain a homogeneous material, an additional homogenization procedure was performed: grinding in a laboratory mill, sieving through a sieve, thorough mixing and conditioning. The certified values of moisture, nitrogen, protein, fat mass fraction for the sample № 1 were accordingly 4,5 %, 14,74 %, 92,1 %, 7,9 %. The same values in the same sequence were 6,3 %, 12,21 %, 76,3 %, 23,8 %.</p><p>The procedure of lyophilisation was developed for production of reference materials for composition of boiled and freeze-dried poultry meat. The usage of this lyophilisation system allowed to ensure a RM expiration date of six months at ambient temperature of (7±3) °C and relative humidity no more than 60 %. The Reference Materials for composition of boiled and freeze-dried poultry meat was added into Register of certified RMs under № GSO 11276-2019 by the results.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пищевые продукты</kwd><kwd>стандартные образцы</kwd><kwd>эталоны</kwd><kwd>первичные референтные методики измерений</kwd><kwd>лиофильная сушка</kwd><kwd>сублимационная сушка</kwd><kwd>показатели пищевой ценности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nutritive products</kwd><kwd>reference materials</kwd><kwd>standards</kwd><kwd>primary reference measurement procedures</kwd><kwd>lyophilisation</kwd><kwd>freeze drying</kwd><kwd>nutritive values</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">ISO Guide 35:2017 Reference materials - Guidance for characterization and assessment of homogeneity and stability.
