Тип записи:Публикация, Providing bioavailability of plant antioxidants using encapsulation processes(American Institute of Physics, 2021-01-01); The purpose of this study was to study the possibility of using technologies for encapsulating flavonoids to ensure their bioavailability. The study evaluated the possibility of using two approaches to encapsulation: encapsulation in β-cyclodextrin and complex coacervation using gelatin and pectin. The effectiveness of the approaches was evaluated by the indicators of total antioxidant activity (DPPH method) and the calculation of the bioactivity index and bioavailability using the in vitro digestion model. The results of determining the total antioxidant activity showed that the encapsulation of taxifolin led to a slight decrease in the values of the indicator, by about 19.3 % when using encapsulation in β-cyclodextrin and 25.4% when using coacervation. The bioactivity index values for the encapsulated forms were 72.4 and 86.8 % when encapsulating in β-cyclodextrin and coacervation, respectively, versus 51.2 % for the original form of taxifolin. Encapsulation technologies made it possible to ensure the safety of taxifolin by 1.2 and 1.8 times in comparison with the control when using encapsulation in β-cyclodextrin and coacervation, respectively. - Некоторые метрики заблокированы вашиминастройками согласия
Тип записи:Публикация, Method for solving the periodic problem for an impulsive system of hyperbolic integro-differential equationsThe periodic problem for a system of integro-differential equations of hyperbolic type with impulse effects is considered. This problem is reduced to an equivalent problem, consisting of a family of periodic boundary value problems for system of ordinary differential equations with parameter and impulse effects and integral relations by method of introducing additional functions. Sufficient conditions for existence of unique solution to the family of periodic boundary value problem with the impulse effects for system of the ordinary differential equations are received by parametrization method. Conditions for the unique solvability of periodic problem for system of integro - differential equations of hyperbolic type with impulse effects are established in the term of initial data.Цитирования (OpenAlex) 2Цитирования (OpenCitations) 2
