   <abstract xml:lang="ru">
    <p>Осетровые объекты товарной аквакультуры становятся сырьевой базой для промышленного производства продуктов питания. Голова осетра – преобладающий по массе отход, рациональная переработка которого позволит полноценно использовать рыбные ресурсы. Цель исследования – изучить химический состав и биологическую ценность тканей головы осетра.&#13;
В качестве объектов исследования использовали мышечную ткань русского осетра (Acipenser gueldenstaedtii) аквакультурного происхождения, головы и продукты их переработки. Для определения химического состава применяли стандартные методы исследования. Биологическую ценность белка рассчитывали согласно методике Продовольственного комитета ФАО/ВОЗ.&#13;
Составлена топография срезов тела осетра в разных частях туловища. Установлено наличие светлой и темной мускулатуры, скопление жировой ткани в подкожной, прихрящевой, брюшной зонах и соединительной ткани в частях тела осетра. Исследование химического состава мяса головы, туловища, хвоста показало содержание воды от 76,0 до 82,9 %; белка – от 14,2 до 18,5 %; жира – от 2,4 до 4,9 %; минеральных веществ – от 0,1 до 0,6 %. Зафиксировано снижение содержания жира в мясе в среднем в 2,8 раза по сравнению с параметрами промыслового осетра. В продуктах переработки головы осетра (мясо и мягкие ткани) белка – 18,6 и 20,4 %; жира – 12,2 и 16,2 %. Данные схожи по составу, но отличаются по пищевой ценности. Биологическая ценность белков мяса головы осетра составила 44,1 %, что на 2,6 % выше этого показателя для мягких тканей. В жире головы осетра установлено содержание мононенасыщенных жирных кислот (45,8 %) и полиненасыщенных жирных кислот ω-3 (11,0 %) и ω-6 (15,2 %).&#13;
Продукты переработки головы осетра являются источниками ценного белка и жира, представляют перспективу для использования в многокомпонентных продуктах питания.</p>

    <p>Sturgeon waste is a raw material base for industrial food production. Sturgeon heads are responsible for the majority of waste, and their rational processing will allow for sustainable utilization of fish resources. This study focused on the chemical composition and biological value of sturgeon head tissues.&#13;
The research featured muscle tissue, heads, and processed products of Russian sturgeon (Acipenser gueldenstaedtii). While the chemical composition was studied by standard methods, the biological value of protein was calculated according to the FAO/WHO Food Committee methodology.&#13;
A topography of various body sections demonstrated the presence of light and dark muscles. Fat tissue accumulated in the subcutaneous, cartilaginous, and abdominal zones, while connective tissue was registered in different body parts. The chemical analysis of flesh from head, body, and tail revealed 76.0–82.9% water contents, 14.2–18.5% protein, 2.4–4.9% fat, and 0.1–0.6% minerals. The average fat content was 2.8 times lower than in commercial sturgeon. Soft tissues of sturgeon head contained 18.6–20.4% protein and 12.2–16.2% fat. These data are similar in composition but differ in nutritional value. The biological value of proteins in the flesh from sturgeon head was 44.1%, which was 2.6% higher than that of soft tissues. Sturgeon head fat contained 45.8% monounsaturated fatty acids, 11.0% ω-3 polyunsaturated fatty acids, and 15.2% ω-6 polyunsaturated fatty acids.&#13;
As reliable sources of valuable protein and fat, sturgeon head recyclables proved to be promising ingredients of multi-component foods.</p>
