Это связано с его химическим составом. Высокое содержание ?-глюканов и пентозанов повышает вязкость массы и потери перевариваемых углеводов на стадии водно-тепловой обработки. Ферменты, используемые для предварительной обработки зерна перед ферментацией, традиционно являются ?-амилазами и глюкоамилазами. Цель работы – определить оптимальное соотношение ферментов, вносимых в различные периоды водно-тепловой обработки. Объектом исследования являлся ячмень: крахмал 52, белок 11,5, гемицеллюлозы 5,1, ?-глюкан 3,9, влажность 14,0. Применяли ферментные препараты Alphaferm 3500L (0,5–1,0 АС/г крахмала), ViscoStar 150L (3700 ед. КС/см3; 140 ед.?–ГкС/см3; 1900 ед. КМЦ/см3.), Prolive BS Liquid (600–750 ед. ПС/см?). Исследована динамика изменения вязкости в процессе водно-тепловой обработки. Установлено, что на массовую долю сухих веществ в фильтрате ячменного замеса наибольшее влияние оказывает дозировка ферментного препарата Alphaferm 3500L, меньшее и близкое по значению влияние – дозировка других ферментных препаратов и продолжительность эксперимента. Показано, что применение мультиферментного комплекса снижает вязкость на 82% по сравнению с контролем. Для определения оптимального режима водно-тепловой обработки был использован метод неопределенных множителей Лагранжа. Установлено, что максимальное накопление сухих веществ в смеси составляет 16,4% и достигается через 2,5 часа при следующих дозах ферментных препаратов: Alphaferm 3500 L – 0,6 ед. АС/г крахмала; ViscoStar 150L – 0,025 ед. ГкС/г крахмала; Prolyve BS Liquide 0,25 ед. ПС/г крахмала.</p></abstract><trans-abstract xml:lang="en"><p>Barley is a problematic raw material for ethanol processing due to its chemical composition. ?-glucans and pentosans high content increases the mass viscosity and digestible carbohydrates loss at еру water-heat treatment stage. The enzymes used to pre-treat grain prior to fermentation are traditionally ?-amylases and glucoamylases. The purpose of the work is to determine the optimal ratio of enzymes introduced in different periods of water-heat treatment. The object of study was barley: starch 52, protein 11.5, hemicellulose 5.1, ?-glucan 3.9, moisture 14.0. Enzyme preparations Alphaferm 3500L (0.5–1.0 AC / g starch), ViscoStar 150L (3700 units KS / cm3; 140 units ? – GcS / cm3; 1900 units CMC / cm3.), Prolive BS Liquid (600-750 units PS / cm?) were used in the work. The dynamics of viscosity change in the process of water-heat treatment was investigated in the work as well. It was found out that the dosage of the enzyme preparation Alphaferm 3500L has the greatest effect on the mass fraction of dry substances in the filtrate of barley mix, while the dosage of other enzyme preparations and the duration of the experiment have a smaller and similar effect. It was proved that the application of a multienzyme complex reduces the viscosity by 82% compared to the control. The method of indefinite Lagrange multipliers was used to determine the optimal mode of water-heat treatment. It was found out that the maximum accumulation of dry substances in the mixture is 16.4% and is achieved after 2.5 hours with the following doses of enzyme preparations: Alphaferm 3500 L - 0.6 units. AC / g starch; ViscoStar 150L - 0.025 units GCS / g starch; Prolyve BS Liquide 0.25 units PS / g starch.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ячмень</kwd><kwd>вязкость</kwd><kwd>оптимизация</kwd><kwd>этанол</kwd><kwd>водно-тепловая обработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>barley</kwd><kwd>viscosity</kwd><kwd>optimization</kwd><kwd>ethanol</kwd><kwd>water-heat treatment</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">Food and Agriculture Organisation of the United Nations (FAO).
