Improvement of water preparation technology for the production of alcoholic beverages of stable quality
(2022) Kuzmin, Oleg; Stukalska (Ivanova), Nataliia; Dudarev, Igor; Mykhailov, Bogdan
It was found that the sodium mass concentration of the prepared water affects the stability of alcoholic beverages during storage. To increase the stability of vodka according to the presented water technology, the following reduction occurs: the mass concentration of sodium (Na) by 23 times – from 266.1 to 11.6 mg/dm3; total alkalinity (TA) by 21 times – from 4.1 to 0.2 mmol/dm3; mass concentration of silicon (Si) by 13 times – from 6.5 to 0.5 mg/dm3; mass concentration of silicic acid (H2SiO3) by 13 times – from 13.9 to 1.1 mg/dm3. Встановлено, що масова концентрація натрію у підготовленій воді впливає на стійкість алкогольних напоїв при зберіганні. Для підвищення стійкості горілки за представленою технологією води відбувається зниження: масової концентрації натрію (Na) у 23 рази – з 266,1 до 11,6 мг/дм3; загальної лужності (TA) у 21 раз – з 4,1 до 0,2 ммоль/дм3; масової концентрації кремнію (Si) у 13 разів – з 6,5 до 0,5 мг/дм3; масової концентрації кремнієвої кислоти (H2SiO3) у 13 разів – з 13,9 до 1,1 мг/дм3.
Influence of chicken meat grinding process conditions on its structural and mechanical characteristics
(2022) Stukalska (Ivanova), Nataliia; Kuzmin, Oleg; Dudarev, Igor
The greatest degree of destruction of the structure is observed in minced leg meat when using all types of grates. This is explained by the structure of the fabric and its chemical composition. An increase in moisture by 1.60 % and a decrease in fat by 1.74 % and protein by 0.95 % leads to the fact that under the influence of tension in pieces of minced meat, regardless of size, there is a faster loss of asthma-related moisture. Moisture under the influence of tension heats up and partially melts the fat droplets in the minced meat, which is due to faster protein denaturation and an increase in the deformation state of the minced meat.
Schematization of functional zones in restaurants according to HACCP
(2022) Kuzmin, Oleg; Polyovyk, Volodymyr; Dudarev, Igor
The purpose of the work is to determine the functional zones in the restaurant management depending on the risk of contamination of raw materials, semi-finished products and finished products. Метою роботи є визначення функціональних зон у закладі ресторанного господарства у залежності від ризику забруднення сировини, напівфабрикатів і готової продукції.
Study of the antioxidant capacity of water-alcohol infusions of coffee substitutes with improved technology of syrups
(2023) Kuzmin, Oleg; Stukalska (Ivanova), Nataliia; Fomenko, Anton; Raiskyi, Mykyta; Dudarev, Igor
Coffee is one of the most popular beverages used worldwide owing to its rich flavor and several health effects. Coffee is an ingredient in various confectioneries, desserts, alcoholic and non-alcoholic cocktails, syrups for dipping in confectionary production, infusions, flavors, etc. Nevertheless, its caffeine content renders its use rather limited for certain individuals warranting for the development of coffee substitutes with similar flavor though with other health effects. Several coffee substitutes are present in the market belonging to different plant organs to encompass a myriad of phytoconstituents. The production of these coffee substitutes expose them to roasting to mimic that of coffee aroma and flavor, concurrent with chemical changes.
