Документ Changes in vitamin content and sensory characteristics of frozen wild berries during storage(2024) Simahina, Galina; Naumenko, Nataliia; Kaminska (Halapsina), SvitlanaThe aim of the study was to evaluate changes in the content of ascorbic acid, bioflavonoids, and β-carotene, as well as the organoleptic properties of frozen wild berries under the influence of cryoprotectants after long-term storage. Berries, processed with a water solution of cryoprotectant before freezing, after 9 months of storage, showed almost no significant difference with fresh raw materials in terms of vitamin content and sensory characteristics. The optimal conditions for defrosting of berries was temperature 0 °C for 30–33 minutes.Документ Functional nutrition to support the health of the population of Ukraine under wartime conditions(2023) Stetsenko, Natalia; Simahina, Galina; Goyko, Iryna; Bashta (Sheremet), AllaThe population of Ukraine has been living in conditions of Russian aggression for more than a year and is in a state of stress due to shelling, uncertainty of the future, risks of loss of life and property, worries for the lives of relatives who are in the ranks of the defense forces or found themselves in territories temporarily not controlled by Ukraine. Under these conditions, the quality of food, drinking water, and the environment deteriorate, with complex negative impacts on people's health. They need particular special nutrition with a full set of necessary essential nutrients, capable of providing physical and psychological endurance, preventing the occurrence and development of somatic, nervous and other types of various diseases. For this, health and functional food products and drinks are needed, which will include a scientifically based selection of physiologically functional ingredients with the necessary medical and biological indicators and directed therapeutic and preventive properties. The research analyses the positive effects of micronutrients that affect physiological processes in the human body during periods of stress and poststress. It is known that in such conditions the metabolism takes place more actively, the consumption of some vitamins and minerals increases, therefore the need for antioxidant vitamins and vitamin cofactors of the body's enzymatic systems increases. There are a number of factors that increase the impact of stress on the human body and, as a result, should be excluded. These include food toxins, alcohol, oxidants, and free radicals. One of the most promising ways to prevent stress and reduce its consequences is to include functional foods and beverages as part of the diet. Their composition should include these functional ingredients, the deficiency of which disrupts the body's adaptive capabilities.Документ Консервування плодово-ягідної сировини з використанням низьких температур та методів кріопротекції(2023) Сімахіна, Галина ОлександрівнаОсновним результатом виконаного дослідження є встановлений експериментальним шляхом факт мінімізації втрат вітаміну С при заморожуванні, зберіганні та дефростації ягід за допомогою кріопротекції. Подальшими дослідженнями планується охопити ширший спектр рослинних об’єктів, у тому числі овочеву сировину, підвищити число придатних для використання ефективних кріопротекторів, вивчити механізм їхньої дії на формування дрібнокристалічного льоду, не агресивного щодо структур рослинних матеріалів, що дасть можливість цілеспрямовано впливати на цей процес. The experimentally stated fact of vitamin C loss minimization (due to cryoprotection during freezing, storage and defrosting of berries) is the main result of this research. The further studies would be aimed at the expansion of the plant objects range, including vegetables, the increase of a number of effective cryoprotectors to use in food industry, and the examination of their impact on formation of fine crystal ice that would not appear to be aggressive towards plant material structures, in order to influence this process purposefully.
