Сокосодержащее коллагеновое рыбное желе готовили согласно разработанной технологии, где очищенную от чешуи и прирезей мяса рыбью кожу промывали и загружали в емкость вместе с сухой поваренной солью (5–10 % от общей массы рыбного сырья) и мелкодробленым льдом (до 25 %) для предотвращения нагревания полученной смеси при последующей ее механической тендеризации за счет вращающихся лезвий ножа-измельчителя в течение 3–5 мин. Полученную смесь промывали водой для удаления соли, загружали промытую кожу в стеклянную емкость вместе с яблочным соком прямого отжима, взятых в массовом соотношении 1:4,5 соответственно, закрывали емкость завинчивающейся крышкой и помещали в холодильник (4±2 ºС) для выдерживания в течение 20–24 ч. Далее набухшую рыбью кожу гомогенизировали при помощи погружного блендера до однородной массы, которую расфасовывали, замораживали (–18 ºС) и хранили до последующего использования. Определена пищевая и энергетическая ценность рыбного коллагенового желе, состоящего из воды (87,4±0,7 %), жира (1,0±0,7 %), белка (4,28±0,28 %), золы (0,28±0,01 %), углеводов (7,0±1,7 %) и содержащего 75,75 ккал. Разработаны рецептуры и получены опытные образцы овсяных шариков и печенья-мюсли без термообработки с сокосодержащим рыбным коллагеновым желе. Дана положительная оценка наработанных опытных образцов кондитерских изделий, обладающих функциональной направленностью и приемлемыми органолептическими показателями качества.</p></abstract><trans-abstract xml:lang="en"><p>The study involved the use of juice-containing collagen hydrate (jelly) obtained from pike-perch (Sander lucioperca) skin as an ingredient in confectionery recipes, such as energy oatmeal balls and granola cookies. Juice-containing collagen fish jelly was prepared according to the developed technology, where fish skin, cleared of scales and meat cuts, was washed and loaded into a container together with dry table salt (5-10% of the total mass of fish raw materials) and finely crushed ice (up to 25 %) to prevent heating of the resulting mixture during its subsequent mechanical tenderization, due to the rotating blades of a chopping knife for 3-5 minutes. The resulting mixture was washed with water to remove salt, the washed skin was loaded into a glass container along with directly squeezed apple juice, taken in a weight ratio of (1:4,5), respectively, the container was closed with a screw cap, and placed in a refrigerator (4±2 ºС) for aging for 20–24 hours. Then the swollen fish skin was homogenized using an immersion blender to a homogeneous mass, which was packaged, frozen (–18 ºС) and stored until further use. The nutritional and energy value of fish collagen jelly was determined, consisting of: water – 87,4±0,7 %; fat – 1,0±0,7 %; protein – 4,28±0,28 %; ash – 0,28±0,01 %; carbohydrates – 7,0±1,7 % and containing 75,75 kcal. Recipes were developed and pilot samples of oatmeal balls and muesli cookies without heat treatment with juice-containing fish collagen jelly were obtained. A positive assessment was given to the developed pilot samples of confectionery products with a functional focus and acceptable organoleptic quality indicators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>овсяные шарики</kwd><kwd>печенье-мюсли</kwd><kwd>сокосодержащий рыбный коллагеновый гидрат</kwd><kwd>тендеризация кожи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oatmeal balls</kwd><kwd>granola cookies</kwd><kwd>fish juice collagen hydrate</kwd><kwd>skin tenderization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в соответствии с утвержденным планом тематик научных исследований ФГБОУ ВО «КГТУ», осуществляемых за счет средств федерального бюджета (бюджетный цикл 2025–2027) с рег. № 1022062900061-5 «Разработка и совершенствование инновационных процессов пищевой инженерии».</funding-statement><funding-statement xml:lang="en">The study was conducted in accordance with the approved plan of research topics of the Federal State Budgetary Educational Institution of Higher Education "KSTU", implemented using federal budget funds (budget cycle 2025-2027) with reg. no. 1022062900061-5 "Development and improvement of innovative processes in food engineering".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Energy Balls Market Size, Share, Industry Trends, Growth Drivers, Opportunities, Key Players Analysis, Regional Outlook and Forecast Report (2025– 2032). – Текст: электронный // The Brainy Insights: сайт. – URL: https://www.thebrainyinsights.com/report/energy-balls-market-13361 (дата обращения: 28.10.2025).</mixed-citation><mixed-citation xml:lang="en">Energy Balls Market Size, Share, Industry Trends, Growth Drivers, Opportunities, Key Players Analysis, Regional Outlook and Forecast Report (2025–2032). – Text: electronic // The Brainy Insights: site. – URL: https://www.thebrainyinsights.com/report/energy-balls-market-13361 (accessed on 28.10.2025).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Energy Balls Market Analysis and Forecast to 2034. – Текст: электронный // Global Insight Services: сайт. – URL: https://www.globalinsightservices.com/reports/energy-balls-market (дата обращения: 28.10.2025).</mixed-citation><mixed-citation xml:lang="en">Energy Balls Market Analysis and Forecast to 2034. – Text: electronic // Global Insight Services: site. – URL: https://www.globalinsightservices.com/reports/energy-balls-market (accessed on 28.10.2025).</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Топ-5 причин чаще есть овсянку. – Текст: электронный // Живая еда: сайт. – URL: https://eda.show/top-5-prichin-chashchie-iest-ovsianku/ (дата обращения: 16.08.2025).</mixed-citation><mixed-citation xml:lang="en">Top 5 Reasons to Eat More Oatmeal. – Text: electronic // Living Food: site. – URL: https://eda.show/top-5-prichin-chashchie-iest-ovsianku/ (accessed on 16.08.2025).</mixed-citation></citation-alternatives></ref><ref id="cit4"><label>4</label><citation-alternatives><mixed-citation xml:lang="ru">Елисеева, Т.
