Представлена динамика электрического импеданса козьего мяса в ходе автолиза. Для проведения исследований предложена электрофизическая методика, позволяющая на основе измерения амплитуды сигнала на образце, сдвига фаз между колебаниями тока и напряжения в цепи рассчитать активную и реактивную составляющие импеданса образца мяса и затем, согласно эквивалентной электрической схеме образца, найти параметры этой схемы – величины электрических сопротивлений и емкостей. Объектом исследования являлись длиннейшая мышца спины козьего мяса, имеющая особую ценность для производства мясных продуктов питания, в том числе функционального назначения. Измерения проводили в частотном диапазоне 10–100000 Гц. Обнаружено, что модуль комплексного сопротивления образцов мышечной ткани уменьшается в течение времени хранения, а зависимость угла сдвига фаз от частоты на частотах 10 – 500 Гц со временем сдвигается в сторону больших частот, причём величина экстремума на частотах около 50000 Гц уменьшается. Анализ зависимости параметров эквивалентной схемы образца от времени автолиза показывает, что данные изменения связаны с синтезом аденозинтрифосфорной кислоты в первые часы после убоя и увеличением проницаемости клеточных мембран. Результаты анализа имеют сходность с показателями при исследовании микроструктуры и изменениям водородного показателя мяса в ходе автолиза. Представленные данные могут быть положены в основу создания электрофизического экспресс-метода контроля автолиза и прогнозирования функционально-технологических свойств систем животного происхождения.</p></abstract><trans-abstract xml:lang="en"><p>The data on the development of meat goat breeding are presented and the prospects of this sub-branch of animal husbandry in obtaining meat products are shown. The dynamics of electrical impedance of goat meat during autolysis is presented. For carrying out of researches the electrophysical method is offered, allowing on the basis of measurement of amplitude of a signal on a sample, phase shift between fluctuations of current and voltage in a circuit to calculate active and reactive components of impedance of a sample of meat and then, according to the equivalent electric scheme of a sample, to find parameters of this scheme - values of electric resistances and capacitances. The object of the study was the longest muscle of the back of goat meat, which has a special value for the production of meat food products, including functional purpose. Measurements were carried out in the frequency range of 10-100000 Hz. It was found that the modulus of complex resistance of muscle tissue samples decreases during storage time, and the phase angle dependence on frequency at frequencies 10 - 500 Hz shifts towards higher frequencies with time, with the value of the extremum at frequencies around 50000 Hz decreasing. Analysis of the dependence of the parameters of the equivalent circuit of the sample on the time of autolysis shows that these changes are associated with the synthesis of adenosine triphosphoric acid in the first hours after slaughter and an increase in the permeability of cell membranes. The results of the analysis have similarity with indicators in the study of microstructure and changes in the hydrogen index of meat during autolysis. The presented data can be used as a basis for the creation of electrophysical express-method of autolysis control and prediction of functional and technological properties of systems of animal origin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрический импеданс</kwd><kwd>мясо коз</kwd><kwd>автолиз</kwd><kwd>мясные продукты</kwd><kwd>развитие козоводства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrical impedance</kwd><kwd>goat meat</kwd><kwd>autolysis</kwd><kwd>meat products</kwd><kwd>goat breeding development</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">Волков А.Д.
