Документ Study of the extraction kinetics of flavonoids from the fruits of sophora japonica L. Sophora Japonica L. with sunflower oil(2024) Pelekhova, Liubov; Usatyuk, Svitlana; Tyshchenko (Usatiuk), Olena; Honcharov, ViacheslavAmong the large number of biologically active substances contained in the fruits of Japanese sophora, the extraction of flavonoids, substances of medium polarity, is particularly important. The process of extracting them with vegetable oil from fruits is quite complicated. The object of research is the kinetics of the process of extracting flavonoids from Japanese sophora fruits with sunflower oil. The influence of temperature, duration, and hydraulic modulus on the extraction process, as well as on the derivation of the equation of the mathematical model, is studied. Mathematical modeling methods are used in the research. Processing of experimental data for the study of extraction kinetics in the vegetable oil:vegetable raw material system is carried out using the Statistica statistical package. In order to derive the equation of the mathematical model of the process of extracting flavonoids from Japanese sophora with sunflower oil, the influence of temperature, duration and hydromodulus on the process of transition of the target component – flavonoids to the extract – is investigated. A mathematical model of the dependence of flavonoids on the hydromodulus (H=10–25), temperature (t=25–45 °С) and the duration of the extraction process of Japanese sophora (τ=2–10 h) is obtained, which makes it possible to calculate the content of flavonoids with an average relative with an error within 5 %. On the basis of the conducted experimental studies, basic technological schemes for obtaining unrefined sunflower oil of increased biological value are developed, which includes the following stages: preparation of raw materials, treatment of prepared raw materials with sunflower oil during dilution and mixing, separation of oil from raw materials by filtering. The proposed technology is promising, as its implementation is possible not only in food industry enterprises, but also in restaurant establishments, as it does not require expensive equipment, additional production premises and special training of personnel. The mathematical models of the extraction process of Japanese sophora with unrefined sunflower oil proposed in the work allow to select the extraction parameters with a high degree of probability and offer the consumer flavonoid-enriched sunflower oil of increased biological value.Документ Improvement of the external traceability system for confectionery products with carob powder using NFC-tags(2023) Bozhko, Anastasiia; Usatyuk, Svitlana; Sydor, Vasyl; Tyshchenko (Usatiuk), OlenaMarket operators develop, implement and constantly improve the traceability system, which ensures an appropriate level of food product safety control.

One of the most problematic places is that the action of the magnetic field and radiation can both stimulate the amylase activity of barley malt and cause its deactivation. During the study, a certain number of electrophysical factors were used, namely: laser radiation, which was carried out using a helium-neon laser, ultraviolet radiation – using a nitrogen gas laser, X-rays, a constant uniform magnetic field, ultrasound. Results have been obtained that confirm the positive effect of the magnetic field on the activation of the amyloletic activity of concentrated preparations. A study was also conducted in accordance with the effect of electromagnetic waves on the activation of enzymes in barley and wheat malt, which showed a positive effect. This is ensured by the fact that in the course of the study, thanks to experiments, the best duration of irradiation with electromagnetic waves and different types of radiation for enzyme preparations, malt and yeast was found. These methods have a number of features. This is the availability of the appropriate equipment and knowledge of the individual types of rays, magnetic fields and electromagnetic waves, and their potential effects on enzymes, as well as control of the exposure time and magnetic field load. Due to the action of electromagnetic waves and radiation, for a certain amount of time, it is possible to obtain an increased activity of enzymatic preparations. Compared to the fermentative preparations Termamil and San- Super, malt and yeast, which are not susceptible to the load of magnetic fields, electromagnetic waves and various types of radiation, the fermentative preparations Termamil and San-Super, malt and yeast, which were susceptible to the action of electromagnetic waves, as well as radiation show increased activity of action. At the same time, these preparations reduce the amount of costs and increase the yield of finished products, which will serve as a positive aspect for the economic sphere of the enterprise. Об’єктом дослідження є ферментні препарати Термаміл та Сан-Супер, солод та дріжджі. Один з найбільш Проблемними місцями є те, що як дія магнітного поля, так і радіація можуть стимулювати активність амілази ячмінного солоду та викликають його дезактивацію. Під час дослідження було використано певну кількість електрофізичних факторів, а саме: лазерне випромінювання, яке було здійснюється за допомогою гелій-неонового лазера, ультрафіолетового випромінювання – за допомогою азотного лазера, рентгенівського випромінювання, постійного рівномірного магнітне поле, ультразвук. Отримано результати, які підтверджують позитивний вплив магнітного поля на активацію амілолетична активність концентрованих препаратів. Також було проведено дослідження щодо ефекту електромагнітних хвиль на активацію ферментів ячмінного та пшеничного солоду, що показало позитивний ефект. Це забезпечується тим, що в ході дослідження, завдяки експериментам, найкраща тривалість опромінення з електромагнітними хвилями та різними видами випромінювання для ферментних препаратів, солоду та дріжджів. Ці способи мають ряд особливостей. Це наявність відповідного обладнання та знання окремі типи променів, магнітних полів і електромагнітних хвиль, а також їх потенційний вплив на ферменти, а також контроль часу експозиції та навантаження магнітного поля. Завдяки дії електромагнітних хвиль і випромінювання протягом певного часу можна отримати підвищена активність ферментативних препаратів. Порівняно з ферментними препаратами Термаміл і Сан- Супер, солод і дріжджі, які не сприйнятливі до навантаження магнітних полів, електромагнітних хвиль і різного роду види радіації, ферментаційні препарати Термаміл і Сан-Супер, солод і дріжджі, які були чутливі до дії електромагнітних хвиль, а також випромінювання виявляють підвищену активність дії. В той самий час, ці препарати зменшують суму витрат і збільшують вихід готової продукції, яка буде служити позитивний аспект для економічної сфери підприємства.Документ Using of white food lupin products in technology of functional bakery products(2013) Arsenieva, Larisa; Dotsenko, Viktor; Bondar, Natalia; Pavliuchenko, Elena; Sharan, Larisa; Tyshchenko (Usatiuk), OlenaThe expediency and the possibility of using protein plant raw material in technology of functional bakery products have been proven.
