Development of the method of obtaining grain flakes using UV-irradiation
(2023) Bazhay-Zhezherun, Svitlana; Bereza-Kindzerska, Ludmyla; Bashta (Sheremet), Alla
The method of obtaining flakes of increased biological value from grain crops has been developed. This method includes preparation of grain for processing, which involves cleaning grain from impurities, sorting, airing, separation of ferromagnetic impurities, washing and disinfection, peeling, hydrothermal treatment at a temperature of 12 - 16° C. Hydrothermal treatment takes place in three cycles, each of which involves intensive moistening of the grain for 4 hours followed by dehydration for 4-6 hours with a total duration of 26 - 30 hours. After the first cycle, the grain is treated with ultraviolet radiation with constant stirring. The thickness of the grain layer is 15 - 20 cm. The wavelength of ultraviolet radiation 250 - 300 nm; radiation intensity is 200 - 260 W/m2. The distance from the grain placement plane to the radiation source is 25 - 30 cm, process duration 55 - 60 sec. The next stage is flattening of raw materials, drying of the flakes at a temperature of 45 - 65° C to a moisture of 12 - 14%, airing, packing. The main physico-chemical and organoleptic indicators of quality of wheat flakes of increased biological value are investigated. The nutritional value of the product is determined. It was investigated that the microbiological seedability of wheat flakes does not exceed the permissible values. Storage for 6 months does not significantly impair quality. The developed method of processing cereals for producing flakes allows to obtain a product with high biological value, namely, an increased content of water-soluble and fat-soluble vitamins, in particular, the content of vitamin E is 8.5 mg%, В1 - 1.12 mg%, В2 - 1.15 mg%; content of food fibers, which are natural food sorbents - 2.5%

Introduction. Cereal products are a source of carbohydrates, protein, macro and micronutrients, vitamins, enzymes, dietary fiber, phospholipids. Sprouting grains is one of the methods for biological activation. Materials and methods. Grains of wheat, triticale and naked oats have been studied. Protein was determined by Bradford method, the starch content – by poalrimetric method. Fat was determined by exhaustive extraction with chemically pure hexane. Vitamins B1, B2, B3, B6 were determined by the method of fluorometry. Vitamins PP and E were determined colorimetrically. Determination of vitamin C was performed by a titration method. Results and discussion. An important task in the process of preparing raw materials for health products is increasing their food and biological value. We proposed a regime of hydrothermal processing of grain at temperatures 12–16 °C. Under these conditions, activation of the enzyme complex, reduction of grain density and increase of its per unit volume; activation of the synthesis of vitamins and vitaminlike substance take place. In the process of biological activation of grain the bioavailability of proteins, carbohydrates, fat increases due to their partial hydrolysis. It has been studied, that the content of fibres,which is natural food sorbent, in biologically activated grains of wheat, naked oats and triticale is respectively 2,68, 2,34, 2,62%. It has been found that in the proposed processing of wheat, triticale and naked oats the quantity of vitamin C increased more than twice. The content of tocopherols increases tenfold, routine – 2,5–3 times. It was established that after hydrothermal treatment the total number of colony-forming units of mesophilic aerobic and facultative anaerobic microorganisms in native and dried corn samples is within the norms established by standards. Conclusions. The results are of practical importance, as they allow to recommend the use of biologically activated wheat, triticale, naked oats for the production of food of health, functional and health-care purposes.

Досліджено, що загальний вміст поліфенолів в екстрактах зеленої маси білкових рослин коливався в межах 8,1–13,3 мг. Загальні концентрації флавоноїдів варіювали від 6,42 до 10,48 мг для досліджених рослинних екстрактів. Експериментально встановлено, що здатність до поглинання радикалів DPPH, для досліджуваних рослин становила від 44,0% до 89,2%. Хоча листя було зневоднене (нагрівання), воно виявило хорошу антиоксидантну активність, що свідчить про те, що зневоднений продукт є джерелом природних антиоксидантів. Результати дослідження показали, що більшість проаналізованих білкових рослин багаті фенольними сполуками та демонструють хорошу антиоксидантну активність. Крім того, високий вміст фенольних сполук та значна лінійна кореляція між значеннями концентрації фенольних сполук та антиоксидантною активністю свідчать про те, що ці сполуки сприяють сильній антиоксидантній активності.Our researches have shown that the DPPH radical scavenging ability expressed as % ranged from 44,0 % for nettle to 89,2 % for ramsons. Although the leaves were dehydrated (heating), they presented good antioxidant activity showing that the dehydrated product is a source of natural antioxidants.Our researches have shown that the DPPH radical scavenging ability expressed as % ranged from 44,0 % for nettle to 89,2 % for ramsons.

(2019) Romanovska, Tetiana; Oseiko, Мykola; Bazhay-Zhezherun, Svitlana; Yarmolitska, Olena
У досліджуваному діапазоні варіювання факторів найістотніше проявився вплив гідромодуля на очищення вовни і на вилучення екстрактивних речовин з поверхні волокна у відпрацьований мийний розчин. Гідромодуль 40 і більший дає змогу очистити вовну від жиру і забруднень. Температура має стабільний вплив у заданому діапазоні, тому всі досліджені значення температури сприяють вилученню жирових забруднень вовни за такого компонентного складу мийного розчину. За гідромодуля 70 і 100, а також концентрації 1 % мас. Sles 70, тобто за концентрацій ПАР, що перевищують критичну концентрацію міцелоутворення (ККМ), волокна вовни також очищаються під час миття. Логічно відзначити, що за концентрацій ПАР, нижчих за ККМ, ефективність очищення вовни знижується. Концентрація ДМСО також мала незначний вплив на очищення вовни порівняно з гідромодулем. Раціональним режимом однократного миття вовни є використання гідромодуля 40, концентрації 1 % мас. Sles 70 і концентрації ДМСО до 0,61 г/дм3 у діапазоні температур 3048 С. Якість миття можна поліпшити, збільшуючи гідромодуль одноразового миття або проводячи кількаразове миття за мінімального гідромодуля. Results and discussion. In the investigated range of variation of factors, the influence of the hydromodule on the purification of wool and the extraction of extractive substances from the surface of the fiber into the waste solution was most pronounced. Hydro module 40 and more allows you to clean the wool from grease and dirt. The temperature has a stable effect in the given range, so all the investigated values of temperature contribute to the removal of fatty contaminations of wool for this component of the detergent solution. Аccording to the hydromodule 70 and 100, as well as the concentration of 1% by weight Sles 70 – that is, for concentrations of surfactants above the critical concentration of micelles (CCM) – the fibers of wool are also cleared during scouring. It is logical to note that the concentrations of surfactants below the CCM have reduced the effectiveness of wool cleaning. The concentration of DMSO also had a slight effect on the wool treatment compared to the hydromodule. Conclusions.The rational mode of single scouring of wool is the use of a hydromodule 40, a concentration of 1% by weight. Sles 70 and DMSO concentration to 0.61 g/dm3 in the temperature range 30−48 С. The quality of the scouring can be improved by increasing the disposable water dispenser or by scouring it with a minimum of water.
