Документ The theoretical description of sucralose cathodic electrochemical determination over a poly(safranin) modified electrode in acidic media(2023) Tkach, Volodymyr; Storoshchuk, Nataliia; Storoshchuk, Bogdan; Oliveira, Sílvio C.; Kryvetskyi, Viktor; Kryvetska, Inna; Kryvetskyi, Igor; Yemelianenko, Nataliia; Narsiia, Valentyn; Yagodynets, Petro; Silva, Adriano; Masna, Zoriana; Shevchenko, Inna; Gnitsevych, Victoriya; Medvedeva, Anzhelika; Vasylieva, Olena; Musayeva, Dilfuza; Kosimov, Xayriddin; Jabborova, Oysha; Samadov, Bakhodirjon; Sagdullayeva, Gulandom; Hamdanova, Gulhayo; Karputina, Margarita; Khargeliia (Karputina), Daria; Garcia, Jarem; Odyntsova, Vira; Martins, José Inácio Ferrão da PaivaFor the first time, sucralose cathodic electrochemical determination, assisted by the safranin-modified electrode in acidic solutions, has been theoretically described. The correspondent mathematical model analysis has shown that the steady-state stability range is wider than in most systems of electrochemical determination over the pyridinic nitrogen-containing conducting polymer. Moreover, the oscillatory behavior is less probable than in similar systems in acidic media. Nevertheless, it is more probable than in neutral media. Nevertheless, poly(safranin) is an efficient electrode modifier for sucralose electrochemical determination.Документ Survey of characteristics of dairy-protein concentrates in the low-temperature storage process(2018) Gnitsevych, Victoriya; Yudina, Tatiana; Deinychenko, Liudmyla; Nykyforov, Radion; Nazarenko, IrynaThe influence of low-temperature freezing parameters and storage time on the quality parameters of milk-protein concentrates (MPC) of buttermilk was studied. The features of low-temperature phase transitions and glass transition of MPC were researched. It was found that the use of viburnum and cranberry purees as coagulants contributes to increasing the proportion of bound moisture and improving the preservation of products. Changes in colorimetric characteristics of the concentrates during storage were determined. The periods and conditions of MPC storage were found.Документ Definition of quality indicators of dairy-protein concentrates in the storage process(2018) Gnitsevych, Victoriya; Yudina, Tatiana; Deinychenko, Liudmyla; Nykyforov, Radion; Nazarenko, IrynaThe aim of this article is to investigate changes in the structure, color and microbiological parameters of milk-protein concentrates (MPC) made of buttermilk with the use of cranberry or viburnum purees in the process of storage. Necessary results were obtained after analyzing phase transitions, changes in color-parametric and microbiological characteristics of the studied products.Документ Research of technological factors impact on obtaining process of dairy-protein co-precipitates with viburnum(2016) Gnitsevych, Victoriya; Deinychenko, LiudmylaВ статті досліджено вплив температури та рН на осадження білків сколотин, обрано режими осадження.
