Документ Effects of multicomponent mixture "Solodok super" on the quality of wheat bread enriched with a sprouted grain mixture(2021) Bilyk, Olena; Burchenko, Liudmila; Bondarenko, Yuliia; Piddubnyi, VolodymyrThis paper is dedicated to improving the technology of bakery products made from wheat flour with added mixture of sprouted grains. The sprouted grain mixture (SGM) contains wheat, barley, corn, and oat grains, produced by “Choice” LLC (Kyiv, Ukraine). It has been proven that increasing the amount of grain mixture to 15% to weight of flour has a negative impact on sensory, physical, and chemical qualities of bread products. This amount of sprouted grain mixture reduces viscosity and increases spreading of dough, which leads to the smaller volume of the finished products. Thus when adding 15% of the mixture, it is recommended to use multicomponent mixtures. Multicomponent mixture "Solodok SUPER" has been developed and its optimal dosage has been established. Using it increases specific volume of bread products and improves their porosity and shape stability.Документ The use of an enzyme preparation when using calcium acetate in wheat bread technology(2019) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Chernyushok, OlgaAn important problem of bakery is the prevention of the main causes of spoilage of bread, namely the development of microorganisms, which, under favorable conditions, become activated and lead to complete unsuitability of the product for consumption. The spores of bacteria of the group of potato sticks are quite resistant to thermal effects, they remain viable even at temperatures close to 130 °C, but are sensitive to an acidic environment. The use of calcium acetate in the recipe of wheat bread to carry out a booming effect on microorganisms will also affect the quality of products. To improve the quality of such products, it is advisable to use amylolytic enzymes to intensify the fermentation of the dough and oxidative additives to reduce its stickiness and spreading. The object of research in the work is dough made from wheat flour of the first grade, the formulation of which includes calcium acetate, the enzyme preparation Alphamalt V and ascorbic acid. It is established that from the point of view of influencing the quality of finished products, a rational dosage of calcium acetate is 0.3 % by weight of flour. The optimal dosage of the enzyme preparation Alphamalt V is 0.015 % by weight of flour and ascorbic acid – 0.006 %. It is proved that the introduction of this composition of food additives improves gas removal ability by 15...20 % compared with the control and products containing only calcium acetate. The positive effect of the use of an enzyme preparation of amylolytic action along with calcium acetate on the lifting force of yeast has been established. This helps to intensify the fermentation of the dough and increase the specific volume and porosity of wheat bread. It is established that the use of a composition of food additives positively affects the elastic-elastic properties of the dough: the spreading of the dough balls decreases and the gas-holding ability increases by 10...13 % compared with products from calcium acetate. This leads to an increase in the specific volume and shape stability of bread. Thanks to the developed composition of food additives, it is possible to use calcium acetate to inhibit potato sticks without losing the quality of the finished product.Документ Studying the effect of the integrated bread baking improver "Mineral freshness super" on consumer properties of wheat bread(2019) Bilyk, Olena; Bondarenko, Yuliia; Kochubei-Lytvynenko, Oksana; Halykova, Esma; Fain, AlbinaScientists from the National University of Food Technologies (Ukraine) developed the integrated bread baking improver "Mineral Freshness Super" whose formulation includes nutritional supplements with the GRAS status. The integrated bread baking improver is composed of a functional base, white pharmacopoeial clay, and an active part ‒ the enzymatic preparations Alphamalt VC 5000 and Novamil 1500MG, maltodextrin, sunflower-derived fat-free lecithin, apple pectin, dry wheat gluten and ascorbic acid. Technological efficiency has been proven to use the integrated bread baking improver "Mineral Freshness Super" in the amount of 1.5 % by weight of flour in order to slow the staling of wheat bread, baked according to the accelerated technology. We have determined regularities in the influence of the integrated bread baking improver "Mineral Freshness Super" on quality of wheat bread. It was established that introducing it to dough results in an increase in the relative volume of products, improves shape formation, porosity, and reduces the duration of fermentation by three times, specifically to 20 min. It has been proven that products with the addition of the integrated bread baking improver "Mineral Freshness Super" retain freshness better, which is confirmed by the increase in the overall deformation of crumb, by a smaller layer under the crust, and by fewer layers of air in the products' crumb. We have observed more accumulation of dextrins and bisulfite binding substances in products when using integrated bread baking improver "Mineral Freshness Super", indicating the inhibition of staling and improvement in consumer properties. Results of our study prove the expediency of using the integrated bread baking improver "Mineral Freshness Super" in the technology of wheat bread to prolong its freshness up to 72 h when storing unpacked.Документ Investigation of influence of inulin made from cycoria on structural-mechanical properties of wheat dough(2019) Bondarenko, Yuliia; Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Halykova, Esma; Fain, AlbinaBread made from wheat flour in chemical composition is not well balanced for vital ingredients. One of its drawbacks is that with a high content of carbohydrates in it there is little dietary fiber, therefore, it is promising to enrich it with inulin-compliant products. The inclusion of inulin made from chicory in the recipe of wheat bread to influence the formation of the rheological properties of the dough, which will affect the quality of the finished products. Therefore, the object of research in the work is the dough of wheat flour of the first grade, the recipe of which includes inulin made from chicory. During the research, inulin made from chicory «Cosucra» (Belgium) is used in the amount of 5, 10, 15 % by weight of flour. It is established that the addition of inulin leads to an increase in the elastic properties of the dough, especially with an increase in the dose of inulin by more than 10 %. Increasing the dose of inulin up to 15 % and more along with an increase in the elastic characteristics reduces the dough elasticity, causing a significant deterioration in the volume of products. It is proven that a decrease in the specific volume of products and an increase in the elastic characteristics of the crumb are the limiting factors of using inulin products in the formulation of more than 10 % by weight of the flour. Use in the formulation of inulin bread in the amount of 10 and 15 % by weight of flour due to the increase in the elastic properties of the dough leads to a significant deterioration in the volume of products. The taste and aroma of inulin products are inherent in wheat bread. Due to the inclusion of inulin wheat bread in the recipe, the products acquire prebiotic properties, however, the effectiveness of using inulin to improve the quality of finished products is possible with dosing 5 % by weight of flour. For greater enrichment of bakery products with dietary fiber, it is possible to use the dosage of inulin 10 % by weight of flour, but to apply technological measures to improve the quality of products.Документ Developing an improver of targeted action for the prolonged freshness of bread made from wheat flour(2020) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Vasylchenko, Tetyana; Pukhliak, AnastasiiaThe development of a complex bakery improver "Freshness CDP SUPER" (Ukraine) to slow down the staling of products developed for accelerated technologies is urgent. It contains nutritional supplements with GRAS status. Whey protein concentrate "CDP-UV-65" was chosen as a functional basis. The active part contains the enzyme preparation Novamil 1500MG, maltodextrin, defatted sunflower lecithin, carboxymethyl cellulose, apple pectin, dry wheat gluten and ascorbic acid. It is proved that with rational dosage of the developed complex bakery improver in the amount of 1.5% to the flour mass, the bread production process is reduced by 180 minutes. It has been established that the bread "Milk Freshness", the recipe of which includes the developed improver, is characterized by a higher specific volume by 10.1% in comparison with the control, porosity, and better shape stability of hearth products. It has been proven that products with the addition of the Freshness CDP SUPER complex bakery improver retain freshness longer, which is confirmed by a 47% greater total crumb deformation compared to the control. The inhibition of staling in bread "Milk Freshness" occurs due to the accumulation of dextrin by 27.1% compared with the control. Thus, the total content of dextrins in wheat bread is 1.918% to DS, and in Milk Freshness bread - 2.438% to DS.The research results prove the expediency of using the complex bakery improver "Freshness CDP SUPER" in the technology of wheat bread in order to extend the preservation period of its freshness up to 72 hours in unpackaged form.Документ Efficiency of sourdoughs of spontaneous fermentation from cereal flour in bakery technologies(2023) Mykhonik, Larysa; Hetman, Inna; Naumenko, OksanaSubject. Sourdoughs of spontaneous fermentation from buckwheat, oat and rice flour, as well as dough and bread with the addition of the above-mentioned sourdoughs. The goal is to investigate the effectiveness of the use of oat, buckwheat and rice sourdoughs of spontaneous fermentation in the technology of bread products of various assortments. Methods. When conducting research, generally accepted methods were used, as well as cause-and-effect analysis, experimental, calculation and logical generalization. Results. In the conditions of the development of discrete production and the popularity of sourdough products, it is effective to use spontaneous fermentation. At the same time, it is worth paying special attention to the search for non–traditional ingredients to improve the nutritional value of wheat flour products and dietary types of bread. The scientific novelty of the results consists in the development and description of the cycles of conducting spontaneous fermentation starters with non-traditional fermentation substrate – green buckwheat, oat and rice flour with further modeling of recipes of bread products of various assortments: wheat, wheat-rye and gluten-free. As a result of the developed management schemes, buckwheat, oat and rice sourdough of spontaneous fermentation was created and the effectiveness of their use in the technology of a wide range of bread products was proven. The feasibility of using buckwheat and oat sourdough in the recipes of wheat and wheat-rye bread, and rice and buckwheat sourdough in the recipe of gluten-free bread is justified. Using the method of trial laboratory baking, the optimal dosages of each leaven were selected and the specifics of using each of them were described, depending on the recipe of the bread. It has been established that the addition of leavens contributes to the improvement of the taste–aromatic properties of the products and more intensive acid accumulation in the dough. Scope of results. The obtained results can be used by manufacturers in the modeling of new and correction of already existing recipes of health and dietary bread.Документ Influence of rice flour on conformational changes in the structure of wheat bread and its nutritional value(2023) Shevchenko, Anastasiia; Litvynchuk (Vorontsova), SvitlanaThe purpose of this paper is determination of the effect of rice flour on the conformational transformations in the structure of wheat bread, which contains lecithin, and its quality indicators. In the last decade, inflammatory bowel diseases, which became a global problem in the world, are a serious threat to human health. In the diet therapy of these diseases, it is recommended not to use a large quantity of dietary fiber. Rice flour is a perspective raw material for production of bakery products for people with this disease, as it contains 8.5 times less dietary fiber than premium wheat flour. Analysis of the chemical composition of bread without rice flour and with its addition showed a slight decrease in protein content by 4.4-10.5%, depending on the dosage (10-40% of wheat flour replacement), and fiber content – by 8.7-35.5%. It was confirmed that conformational changes occur in the structure of proteins and other nutrients of the product in bread making process. The changes of structural groups and their redistribution in the dough after kneading at once and after 3.5 hours of its fermentation and in bread when part of the wheat flour is replaced with rice flour were analyzed. The utilitarian coefficient, redundancy coefficient, DKAS and the indicator of biological value indicated that it is rational to make a replacement of wheat flour with 10% or 20% of rice flour.Документ Збагачена мінеральними речовинами молочна сироватка як перспективний поліпшувач якості хліба(2015) Кочубей-Литвиненко, Оксана Валер'янівна; Білик, Олена АнатоліївнаУ статті розглянуто аспекти використання молочної сироватки у хлібо пекарській галузі для поліпшення якості хлібобулочних виробів і підвищення їх харчової цінності, особливо мінерального складу.

Oil seeds, in particular flax seeds, are an important source of dietary fiber, complete protein, unsaturated fatty acids, minerals and vitamins for enriching various bakery products. The research used the seeds of golden flax. According to the research results, it was found that it is technologically possible to dose crushed flax seeds to the wheat bread recipe up to 20% by weight of flour, and up to 15% by weight of flour as a whole. With such a dosage, products with developed porosity were obtained with pleasant light yellow coloured crumb and pleasant nutty flavor. The paper considers the possibility of using crushed golden flax seeds in the recipe of bakery products from puff yeast dough According to the results of laboratory baking and graph-mathematical method of optimization by a complex indicator of quality and integrated score of products, it was established that it is advisable to add up to 15% of crushed flax seeds to the recipe of puff products. The use of crushed flax seeds as a part of puff products allowed to reduce the amount of margarine for layering dough from 35% to 20% to the weight of the dough and to enrich products with unsaturated fatly acids of flax seeds. In the technology of lamb products enriched with flax seeds, it is recommended to dose flax seeds in the amount of 15% by weight of flour. Products with such dosing received the highest number of points of a complex indicator of quality and correspond to requirements of regulatory documentation. The paper considers the possibility of creating organic bakery products of low humidity for special purposes. “Grisini” bread sticks, which were made from organic raw materials, were chosen as the object of enrichment. To increase the nutritional value of bread sticks and enrich them with such physiologically functional ingredients as unsaturated fatty acids, lignans, dietary fiber, it is promising to use flax seeds. It was found that it is advisable to include organic seeds of golden flax in the formulation of bread sticks up to 25% by weight of flour.Документ Вплив суміші пророщених зернових культур на основні технологічні параметри і якість хліба пшеничного(2020) Білик, Олена Анатоліївна; Бурченко, Людмила Миколаївна; Халікова, Есма Фаїківна; Йолтухівська, Аліна ВасилівнаУ статті доведено доцільність використання суміші пророщених зерен у технології хлібобулочних виробів з пшеничного борошна. Суміш пророщених зернових культур має у своєму складі зерна пшениці, ячменю, кукурудзи, вівса компанії «CHOICE» (м. Київ, Україна). Встановлено, що суміш пророщених зерен має високу автолітичну активність і кислотність, характеризується низькою білістю та має сірий колір. Дослідження впливу суміші пророщених зерен на якість хлібобулочних виробів підтвердили, що у разі внесення 5% суміші пророщених зерен комплексний показник якості становить 94 бали, 10% — 85 балів, 15% — 72 бали. Тобто зі збільшенням внесення суміші погіршуються показники якості хліба пшеничного, але при цьому встановлено підвищення харчової цінності. У виробах з 15% суміші пророщених зерен збільшується вміст мінеральних речовин, підвищується на 43,0% порівняно з контрольним зразком вміст вітамінів (зокрема тіаміну), що задовольняє добову потребу в них на 70%. Аналіз досліджень показав, що внесення в тістову систему суміші пророщених зерен зменшує вміст сирої клейковини у тісті з 23,6%> до 20,1% у разі використання 15% суміші. Завдяки використанню суміші пророщених зерен скорочується тривалість замішування тіста та зменшується його стійкість, скорочується тривалість підйому тіста, порівняно з контролем, на 6... 17,0%. У процесі зберігання показники структурно-механічних властивостей м ’я- кушки із сумішшю пророщених зерен знижувалися повільніше, ніж у контрольному зразку. Так, через 72 год ступінь збереження свіжості хліба пшеничного із суміші пророщених зерен на 15... 50% вищий, якщо порівняти з контролем. Це пояснюється впливом активних амілолітичних ферментів, внесених із сумішшю пророщених зерен на уповільнення ретроградації крохмалю м’якушки хліба та підвищення її гідрофільних властивостей, що дає змогу зберігати свіжість виробів впродовж 24... 72 годин. The work is devoted to establishing the feasibility of using a mixture of germinated grains in the technology of bakery products made from wheat flour. The mixture of germinated grains contains wheat, barley, com and oat, produced by the company “CHOICE” (Kyiv, Ukraine). It was found that the mixture of germinated grains has high autolytic activity and acidity, low whiteness and gray color. Studies of the effect of the mixture of germinated grains on the quality of bakery products found that in the case of adding 5% of the mixture, the complex quality index is 94 points, in the case of using 10% — 85 points, and in the case of adding 15% — 72 points. That is, with increasing the introduction of the mixture the quality of wheat bread deteriorates, but at the same time nutritional value increases, namely: the content of minerals increases, the provision of vitamins (in particular thiamine) in wheat bread with 15% of the mixture reaches 70.0% of the daily need, which is 43.0% more than in the control sample. Analysis of studies has shown that the introduction of a mixture of germinated grains into the dough system reduces the content of wet gluten in the dough from 23.6% to 20.1% when using 15% of the mixture. It has been found that the use of germinated grains reduces the dough kneading time and decreases its stability, reduces the duration of the dough rise by 6... 17.0% compared to the control sample. During storage the structural and mechanical properties of the crumb with a mixture of germinated grains decreased more slowly than in the control sample. Thus, after 72 hthe degree of preservation of freshness of wheat bread from the mixture of germinated grains was 15...50% higher than in the control sample. This is due to the effect of active amylolytic enzymes, imported from the mixture of germinated grains, on the retro- gradation of the bread crumb starch and increasing its hydrophilic properties, which allows the products to remain freshness for 24...72 hours.
