Приведены сравнительные данные по потерям каротиноидов при термической обработке формованной пищевой продукции из промытого фарша для эмульсий крилевого жира на основе казеината натрия (КЭ), лецитина (ЛЭ) и их композиции (КЛЭ). Исследование образцов после варки выявило, что в результате термической обработки снижение потерь каротиноидов наблюдается во всех образцах, при этом наилучший эффект был достигнут для КЭ, где потери снижаются на    9,6 % в случае с непромытым фаршем и на 11,3 % в случае с фаршем, промытым ЭХА-раствором. Наиболее высокое значение предельного напряжения сдвига (ПНС) до замораживания отмечено для полуфабрикатов из фаршей, промытых ЭХА-раствором с внесением КЭ (6950 Па), однако при этом отмечалась достаточно крошливая консистенция. Наилучшее соотношение реологических и органолептических характеристик до замораживания наблюдалось в промытых фаршах с добавлением КЛЭ, при этом значение ПНС фарша, промытого ЭХА-раствором, составило 5000 Па, что превышало более чем в 2 раза аналогичный показатель в образцах непромытого фарша (2350 Па). После размораживания использование КЛЭ позволило сохранить необходимый уровень органолептических показателей сырых изделий – пластичность и отсутствие рассыпчатой структуры. Сделано предположение о том, что казеинат натрия, по всей видимости, способствует формированию устойчивых, достаточно вязких эмульсионных структур, у которых белковые оболочки масляных капель сами способны кополимеризоваться или механически переплетаться с основной миозиновой белковой сетью. </p></abstract><trans-abstract xml:lang="en"><p>The structural and mechanical characteristics of minced fish washed with an electrically activated sodium chloride solution after its enrichment with preemulsified krill oil have been determined using penetration and organoleptic methods. Comparative data are presented on carotenoid losses during heat treatment of molded food products from washed minced fish for krill oil emulsions based on sodium caseinate (CE), lecithin (LE) and their composition (CLE). The study of samples after cooking has showed that as a result of heat treatment, a decrease in carotenoid losses is observed in all samples, with the best effect achieved for CE. The highest value of the yield stress (YS) before freezing has been noted for semi-finished products made from minced fish washed with an electrically activated solution with the addition of CE (6950 Pa), however, a rather crumbly consistency has been noted. The best ratio of rheological and organoleptic characteristics before freezing has been observed in washed minced fish with the addition of CLE, while the YS of minced fish washed with an electrically activated solution is 5000 Pa, which is more than 2 times higher than the same indicator in samples of unwashed minced fish (2350 Pa). After defrosting, the use of CLE allowed maintaining the required level of organoleptic characteristics of raw products: plasticity and the absence of a crumbly structure. It has been suggested that sodium caseinate apparently promotes the formation of stable, fairly viscous emulsion structures in which the protein shells of oil droplets themselves are capable of copolymerizing or mechanically intertwining with the main myosin protein network. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>крилевый жир</kwd><kwd>каротиноиды</kwd><kwd>предельное напряжение сдвига</kwd><kwd>астаксантин</kwd><kwd>электрохимически активированный раствор</kwd><kwd>казеинат натрия</kwd><kwd>лецитин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>krill oil</kwd><kwd>carotenoids</kwd><kwd>yield stress</kwd><kwd>electrochemical activated solute</kwd><kwd>minced fish</kwd><kwd>sodium caseinate</kwd><kwd>lecithin</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">Андрюхин, А.
