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 Implementation of new technology of confectionery products in restaurant establishments(2023) Kyrpichenkova, Oksana; Sylchuk, Tetiana; Zuiko, Vira; Nazar, Mariana; Tsyrulnikova, Vita; Tyshchenko (Usatiuk), Olena; Pushka, Olga; Bortnichuk, OlegСтаття присвячена питанням створення нових технологій кондитерських виробів, що відповідають сучасним тенденціям харчування за рахунок підвищення їх харчової цінності. Розроблені продукти також мають збільшений термін зберігання. Такі характеристики продукту отримані в результаті використання пектинвмісної рослинної сировини, глюкозо-фруктозного сиропу та комплексного поліпшувача. У ході дослідження було вивчено вплив гідролізату морквяно-гарбузового пюре та комплексного покращувача «Магімікс Свіжість» на якість та термін зберігання кондитерських виробів. За допомогою методу термографії було виявлено, що при додаванні моркви і гарбузових гідролізованих пюре до тіста, кількість осмотично та адсорбційно зв'язаної вологи та енергія її активації зросли. За рахунок взаємодії біополімерів кількість щільно зв’язаної води тіста та овочевих пюре зросла. Це збільшує термін зберігання заварних тістечок до 4,5 місяців. Визначено вплив в'язкості тіста на формування структури тістових мас і готових виробів. Виявлено, що спостерігається збільшення вміст біологічно активних речовин у готовій продукції, зокрема вітамінів, переважно β-каротин, водорозчинний пектин, клітковина та мінерали. Це дозволяє розширити термін зберігання продукції в закладах ресторанного господарстваДокумент 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. The elements of the traceability system are internal and external traceability. The purpose of this work is to improve the elements of the external traceability system for the circulation of confectionery products with carob powder using NFC tags. The production of confectionery products with carob powder is promising, as it allows reducing the amount of sugar in the recipe composition of the product. A block diagram of the traceability system of raw materials and finished products in the production of confectionery products with carob powder is proposed. Presented the introduction of a traceability system in the production of flour confectionery products with carob powder in accordance with the requirements of the GS1. The analysis of modern means of automated identification of food products, such as barcode encoding (1D, 2D), blockchain technologies, RFID, and NFC, has been conducted. Contemporary tools for ensuring traceability through the automation of information recording regarding the identification and traceability of food products at all stages of their production optimize the documentation system on various types of media. 95 Харчові технології NFC information scanning technology allows data exchange between devices at a distance of up to 10 cm. Due to its compact size and low power consumption, this technology is used in small digital mobile devices. Improving traceability using NFC-technology is accessible to all market operators, as it does not require additional equipment and provides convenient access to a significant amount of information about the food product
