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 The plant half products for fortification of foodstuffs(2023) Simahina, Galina; Naumenko, NataliiaThe subjects for researching are the green parts (tops) of beets, ramsons, nettle, garlic, pea husk, and onion skin. We confirmed the high content of indispensable amino acids – 87 to 283 mg per 100 g of leucine; 72 to 205 mg per 100 g of lysine; 504 to 1375 mg per 100 g in total. Dispensable amino acids in maximal amount are represented by glycine (83 to 377 mg per 100 g), alanine (87 to 251 mg per 100 g). Proteins in researched materials are outstanding with high grade of proteolysis (28.61 % for garlic; 28.81 % for nettle; 29.37 % for sugar beet), which slightly differs from the control index (milk proteins, 30.01 %). Taking green mass for a base to create the biologically active additives and polyfunctional ingredients is grounded scientifically, expedient technologically, and profitable economically. We have recommended using the green mass of plants for enrichment of any food bases in production of foodstuffs for both domestic and foreign markets.
