Холодный способ приготовления кофе относительно новый.</p><p>   Целью работы являлось исследование динамики биологически активных соединений и антиоксидантной активности при экстрагировании кофе холодным способом на примере кофе арабика, реализуемого на российском потребительском рынке.</p></sec><sec><title>   Методы</title><p>   Методы. Экстрагирование осуществляли в течение 24 часов в двух вариантах, отличающихся температурой воды для экстрагирования (+20°С и +4°С). В разновременные интервалы (5 минут, 1, 3, 6, 12 и 24 часа) в экстрактах определяли: спектрофотометрически содержание кофеина, сумму хлорогеновых кислот, фенольные соединения;антиоксидантную активность кулонометрическим методом. Контролем служил экстракт кофе, заваренный в френч прессе в течение 5 минут горячим способом.</p></sec><sec><title>   Результаты</title><p>   Результаты. Основная часть биологически активных соединений перешла в экстракт через 6 и 12 часов при использовании для экстрагирования воды температурой +20°С и +4°С, соответственно, составляя более 90 и 95 % от их общего количества, экстрагированного за 24 часа. В то же время их антиоксидантная активность составила только 83,89 и 87,45 %. Содержание биологически активных соединений и антиоксидантная активность экстрактов достигла или превысила контроль после 24 часов экстрагирования. В напитках, приготовленных в течение 6 и 24 часов (температура воды +20 °С) и 12 и 24 часов (температура воды +4 °С), дополнительно определяли растворимые сухие вещества, рН, титруемую кислотность, интенсивность коричневого цвета. При более высокой температуре за 24 часа экстрагирования кофе приобретает горький привкус, что снижает его органолептическую оценку.</p></sec><sec><title>   Заключение</title><p>   Заключение. Для формирования оптимальных органолептических и антиоксидантных свойств при приготовлении кофе арабика холодным способом можно использовать воду температурой +20 °С и +4 °С с продолжительностью экстрагирования 6 и 24 часа соответственно.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. Cold brewing is a relatively new method of preparing coffee.</p><p>   The goal research was to study the dynamics of biologically active compounds and antioxidant activity during cold extraction of coffee using Arabica coffee sold on the Russian consumer market.</p></sec><sec><title>   The Methods</title><p>   The Methods. Extraction was carried out for 24 hours in two versions differing in the temperature of the water for extraction (+20 °C and +4 °C). At different time intervals (5 minutes, 1, 3, 6, 12 and 24 hours) the following were determined in the extracts: spectrophotometrically for caffeine content, the amount of chlorogenic acids, phenolic compounds; antioxidant activity by the coulometric method. The coffee extract brewed in a French press for 5 minutes using the hot method served as a control sample.</p></sec><sec><title>   The Results</title><p>   The Results. The main part of biologically active compounds passed into the extract after 6 and 12 hours when using water at a temperature of +20 °C and +4 °C for extraction, respectively, constituting more than 90 and 95 % of their total amount extracted in 24 hours. At the same time, their antioxidant activity was only 83.89 and 87.45 %. The content of biologically active compounds and the antioxidant activity of the extracts reached or exceeded the control after 24 hours of extraction. In drinks prepared for 6 and 24 hours (water temperature +20 °C) and 12 and 24 hours (water temperature +4 °C), soluble dry substances, pH, titratable acidity, and brown color intensity were additionally determined. At a higher temperature, coffee acquires a bitter taste during 24 hours of extraction, which reduces its organoleptic assessment.</p></sec><sec><title>   The Conclusion</title><p>   The Conclusion. To form optimal organoleptic and antioxidant properties when preparing Arabica coffee using cold brewing method, water at a temperature of +20 °C and +4 °C can be used with an extraction time of 6 and 24 hours, respectively.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кофе</kwd><kwd>температура экстрагирования</kwd><kwd>кофеин</kwd><kwd>хлорогеновые кислоты</kwd><kwd>фенольные соединения</kwd><kwd>антиоксидантная активность</kwd><kwd>физико-химические показатели</kwd><kwd>органолептическая оценка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coffee</kwd><kwd>extraction temperature</kwd><kwd>caffeine</kwd><kwd>chlorogenic acids</kwd><kwd>phenolic compounds</kwd><kwd>antioxidant activity</kwd><kwd>physicochemical parameters</kwd><kwd>organoleptic assessment</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">Parameters on antioxidant activity and caffeine content in infusions of roasted and unroasted arabica coffee beans originated from different countries Muzykiewicz-Szymańska A.
