Abstract This paper reveals the technological properties of lactic acid bacteria isolated from raw milk (colostrum and mature milk) of Wagyu cattle raised in Okayama Prefecture, Japan. Isolates were identified based on their physiological and biochemical characteristics as well as 16S rDNA sequence analysis. Streptococcus lutetiensis and Lactobacillus plantarum showed high acid and diacetyl-acetoin production in milk after 24 h of incubation at 40 and 30°C, respectively. These strains are thought to have potential for use as starter cultures and adjunct cultures for fermented dairy products.

Представлен комплексный подход к оптимизации состава мучной поликомпонентной смеси для ржано-пшеничных хлебобулочных изделий, учитывающий химический состав и технологические свойства пищевых ингредиентов смеси, а также их влияние на основной технологически формирующий компонент – ржано-пшеничную муку. Проектирование состава поликомпонентных смесей осуществляли с помощью разработанной ранее программы. Было сгенерировано более 20 образцов модельных мучных смесей, из которых отобрано 4 образца с показателями биологической ценности не менее 70% для приготовления хлебобулочных изделий. Приготовление осуществляли ускоренным способом с использованием подкислителя «Лезизауэр», прессованных дрожжей и соли в количестве, % от массы смеси, 2,0; 2,2 и 1,5 соответственно. Воду вносили по расчету с учетом массовой доли влаги ингредиентов. Продолжительность брожения составляла 60–70 мин, расстойки – 35–40 мин. Изделия выпекали при (200 ± 10)ºС до температуры внутри мякиша 97–98ºС. В качестве контроля был приобретенный в торговой сети хлеб ржано-пшеничный «Спасский», выпеченный АО «Орловский хлебокомбинат». Установлено, что выпеченные образцы ржано-пшеничного хлеба из разработанных мучных поликомпонентых смесей имеют сбалансированный состав белков, жиров и углеводов – 1,0 : 0,8 : 3,9–4,8 соответственно и кальция, фосфора и магния – 1,0 : 0,5–0,6 : 1,2–1,5 соответственно. По сравнению с хлебом ржано-пшеничным «Спасский» в хлебобулочных изделиях из мучных поликомпонентных смесей повысилось содержание белка и липидов соответственно на 0,8–2,3 и 2,7–3,5%, количество углеводов снизилось на 5,5–7,2%, увеличилось количество клетчатки в 4,5–5,5 раза, кальция в 5,5–7,5 раза, фосфора в 1,5–1,6 раза, магния в 1,1–1,2 раза. Биологическая ценность разработанных хлебобулочных изделий повысилась на 7,9–18,4% в сравнении с контрольным образцом. A comprehensive approach to optimizing the composition of a multi-component flour mixture for rye-wheat bakery products, taking into account the chemical composition and technological properties of the food ingredients of the mixture, as well as their influence on the main technologically forming component – rye-wheat flour, is presented. The design of the composition of multicomponent mixtures was carried out using a previously developed program. More than 20 samples of model flour mixtures were generated, of which 4 samples with indicators of biological value of at least 70% were selected for the preparation of bakery products. Preparation was carried out by an accelerated method using the acidifier «Lezisauer», compressed yeast and salt in an amount, % of the mass of the mixture, 2,0; 2,2 and 1,5 respectively. Water is added according to the calculation taking into account the mass fraction of moisture of the ingredients. The duration of fermentation was 60–70 minutes, proofing – 35–40 minutes. The products were baked at (200 ± 10)°C to the temperature inside the crumb 97–98°C. The rye-wheat bread «Spassky» purchased in the retail chain was used as a control. It was found that the baked samples of rye-wheat bread from the developed multi-component flour mixtures have a balanced composition of proteins, fats and carbohydrates – 1,0 : 0,8 : 3,9–4,8 respectively and calcium, phosphorus and magnesium – 1,0 : 0,5–0,6 : 1,2–1,5 accordingly. Compared with rye-wheat bread «Spassky» in bakery products made from flour multicomponent mixtures, the content of protein and lipids increased respectively by 0,8–2,3 and 2,7–3,5%, the amount of carbohydrates decreased by 5,5–7,2%, the amount of fiber increased by 4,5–5,5 times, calcium by 5,5–7,5 times, phosphorus by 1,5–1,6 times, magnesium by 1,1–1,2 times. The biological value of the developed bakery products increased by 7,9–18,4% in comparison with the control sample.

При производстве табачного сырья важную роль играет сокращение продолжительности сушки табачных листьев. Одним из способов интенсификации сушки свежеубранных табачных листьев является прием прорезания средней жилки (ПСЖ) листьев вдоль волокон. По результатам исследований 2019–2020 гг. была создана база данных табачного сырья, полученного при естественном способе сушки с применением приема ПСЖ, которая может служить информационным материалом для производителей табака. Проведена оптимизация процесса сушки табачного листа ПСЖ по показателям качества табачного сырья для расширенного диапазона сортотипов табака. Объектом исследований были сорта отечественной селекции, включенные в Государственный реестр селекционных достижений, допущенные к использованию: Самсун 85, Вирджиния 202, Юбилейный новый 142, Трапезонд 92, Трапезонд 204, Дюбек 33, Американ 287 и Крупнолистный Ильский (находится в стадии государственных испытаний). Критерием оценки эффективности применения приема ПСЖ на исследованных сортах табака являлся совокупный сравнительный анализ следующих показателей контрольных (без ПСЖ листа) и опытных образцов: уровень интенсификации сушки, показатели товарного качества, технологических свойств и химического состава полученного сырья. Установлено, что ПСЖ позволяет интенсифицировать процесс сушки в 1,3–2,46 раза в зависимости от сорта табака и положительно влияет на технологические свойства сырья, у большинства сортов увеличивается выход волокна и сохраняются объемно-упругие свойства. Динамика сушки оказывает влияние на изменение химического состава сырья. В процессе сушки за счет гидролизации солей никотина и его освобождения путем окисления кислородом воздуха уровень никотина в ряде образцов снижается в пределах 10–30%. Чем выше содержание никотина, тем выше крепость табака, грубее его вкус. Изменения углеводно-белкового соотношения в сторону повышения углеводов улучшают вкусовые характеристики сырья. По каждому исследованному сорту не удалось выявить закономерной зависимости его структуры и характера процесса сушки при ПСЖ с преобразованиями химического состава сырья. На основе анализа технологических и качественных показателей табачного сырья, представленных в разработанной базе данных по интенсификации сушки различных сортов табака с применением приема ПСЖ табачных листьев, можно планировать выбор оптимального способа сушки для каждого сорта табака, позволяющего повысить эффективность использования сырья и улучшить его качественные характеристики. In the production of tobacco raw materials, reducing the drying time of tobacco leaves plays an important role. One of the ways to intensify the drying of freshly harvested tobacco leaves is the method of cutting the middle vein (CMV) of the leaves along the fibers. Based on the results of research in 2019–2020, a database of tobacco raw materials obtained by a natural drying method using CMV reception was created, which can serve as information material for tobacco producers. The optimization of the process of drying the CMV tobacco leaf according to the quality indicators of tobacco raw materials for an expanded range of tobacco variety types was carried out. The object of research was the varieties of domestic selection included in the State Register of Breeding Achievements, approved for use: Samsun 85, Virginia 202, Yubileyny novy 142, Trapezond 92, Trapezond 204, Dubek 33, American 287 and Krupnolistnyy Ilskiy (under state testing). The criterion for evaluating the effectiveness of the use of CMV intake on the studied tobacco varieties was a cumulative comparative analysis of the following indicators of control (without CMV sheet) and experimental samples: the level of drying intensification, indicators of commercial quality, technological properties and chemical composition of the obtained raw materials. It is established that CMV allows to intensify the drying process by 1,3–2,46 times, depending on the tobacco variety and has a positive effect on the technological properties of raw materials, most varieties increase the yield of fiber and retain volume-elastic properties. The dynamics of drying affects the change in the chemical composition of raw materials. During the drying process, due to the hydrolysis of nicotine salts and its release by oxidation with air oxygen, the nicotine level in a number of samples decreases within 10–30%. The higher the nicotine content, the higher the strength of tobacco, it is coarser in taste. Changes in the carbohydrate-protein ratio in the direction of increasing carbohydrates improve the taste characteristics of raw materials. For each studied variety, it was not possible to identify a regular dependence of its structure and the nature of the drying process at CMV with transformations of the chemical composition of raw materials. Based on the analysis of technological and qualitative indicators of tobacco raw materials presented in the developed database on the intensification of drying of various varieties of tobacco using the use of CMV of tobacco leaves, it is possible to plan the choice of the optimal drying method for each variety of tobacco, which allows to increase the efficiency of using raw materials and improve its quality characteristics.
