    Perspective ways to increase the preventive benefits of kombucha
    (Національний університет харчових технологій, 2024) Diatel, Oleh; Grynevych, Oksana
    На сьогоднішній день на комерційному ринку безалкогольних напоїв України, Європи та США стрімко набуває популярності ферментований напій під назвою «комбуча». Цей напій має позитивний профілактичний та оздоровчий вплив на організм людини завдяки своєму унікальному біохімічному складу. Приготовлена комбуча, відома як «чайний гриб», багата на вітаміни, мінерали, різноманітні антиоксиданти та корисні кислоти.

    Impact of lyophilization on the chemical composition and metabolic activity of plant extracts
    (2024) Bondar, Hanna; Grynevych, Oksana
    One of the effective methods for preserving the quality and shelf life of plant extracts is the lyophilization technology, where the solvent is removed at low temperatures under vacuum by sublimation. A search and analysis of scientific works were conducted regarding the advantages and disadvantages of lyophilization and its influence on the composition of secondary metabolites in plant extracts. Lyophilization is widely used for concentrating extracts, preserving their properties, and extending their shelf life in the pharmaceutical, food, and chemical industries. Among the disadvantages are high costs for equipment, energy, and labor resources. Lyophilization may reduce the amount of volatile compounds or decrease the metabolic activity of components, which is particularly relevant in the pharmaceutical and food industries. In a study of lyophilization of root extracts, it was found that 7% of wheat metabolites are lost, and 43% exhibit modified activity. Comparison of different drying methods showed that oven drying post-extraction leads to a loss of up to 27% of metabolites in aqueous extracts, while in 50% ethanol extracts, the losses are only 3%. Research on the impact of lyophilization on the composition of metabolites and their biological activity remains relevant.
