Change in Sunflower Oil Quality and Safety Depending on Number of Deodorisation Cycles Used.

Deodorisation remains a beneficial aspect of the processing of edible oils and fats and is required during the first refining and after transportation, storage, and/or further processing, such as interesterification. While there is awareness among the scientific community that repeated deodorisation may negatively impact product quality, according to some technical and processing requirements, oils, fats, and their blends can still be treated with up to 3-4 cycles of deodorisation. However, the precise changes caused by sequential deodorising processes remain unknown.

[Estimation of gammaaminobutyric acid intake from the human diet].

Gamma-aminobutyric acid (GABA) is an endogenous bioactive compound with essential properties for the normal functioning of the human nervous system. As a potent neurotransmitter, it plays an important role in modulating synaptic transmission by exerting phasic inhibition of neurons. This and other effects of GABA provide the phenomenon of neural tissue plasticity underlying learning, memory, maturation and repair of neural tissue after damage.

[Physiological and biochemical study of polyphenols and 20-hydroxyecdisone from quinoa grains effect on resistance to physical exercise in Wistar rats].

Increasing the ability of the human body to adapt to physical stress is relevant from the standpoint of using foods for special uses containing functional food ingredients (FFI) with effectiveness proven in vivo. of this study was to evaluate the effect of FFI from Chenopodium quinoa grains with a high content of polyphenols and phytoecdysteroids on the physical endurance of male Wistar rats. .

[Study of the sorptiondesorption of ecdysterone (20 E) as part of adaptogenic compositions with inulin and functional food ingredients based on spinach and quinoa].

The main principle in the enrichment of food with minor bioactive compounds is the prediction and evaluation of possible chemical interactions of the components included in the matrix of the food. These interactions have a impact on the bioavailability of minor bioactive compounds. In our work, we studied the processes of sorption and desorption (release), the main processes affecting the bioavailability of the minor bioactive compound ecdysterone (20 E) in the composition of functional food ingredients obtained from spinach leaves (FFI-1) and quinoa grains (FFI-2) on hydrocolloid matrix - inulin.

Nonreciprocal collective magnetostatic wave modes in geometrically asymmetric bilayer structure with nonmagnetic spacer.

Nonreciprocity, inequivalence in amplitudes and frequencies of spin waves propagating in opposite directions, is a key property underlying functionality in prospective magnonic devices. Here we demonstrate experimentally and theoretically a simple approach to induce frequency nonreciprocity in a magnetostatically coupled ferromagnetic bilayer structure with a nonmagnetic spacer by its geometrical asymmetry. Using Brillouin light scattering, we show the formation of two collective spin wave modes in FeGa/Cu/FeGa structure with different thicknesses of ferromagnetic layers.
