In this paper, conventional solid-liquid extraction and ultrasound-assisted extraction were utilized for (poly)phenols extraction from black elderberry flowers. The extraction lasted 30 to 120 min, with a solid-to-solvent ratio of 1:15 w/v and 1:30 w/v and solvents of 30% and 60% ethanol. Total (poly)phenols, flavonoids and anthocyanins contents we...

Fat soluble vitamins, including vitamin D, are not sufficiently represented in the human diet. Although vitamin D can be synthesized in the body by direct exposure of the body to the sun, often people don’t get enough sun exposure to assure enough vitamin D. Previous research has established that vitamin D deficiency is considered to be a hig...

The concentration of copper (Cu) was determined in 110 samples of fruit (n = 31) and vegetable products (n = 79), collected during the period from January 2015 to December 2019. Fruit and vegetable products originate from 17 countries, including Serbia. Samples were analysed by inductively coupled plasma – optical emission spectrometry (ICP-O...

The aim of the present study was the characterization of silymarin and silibinin liposomes via determination of encapsulation efficiency, particle size, polydispersity index (PDI), zeta potential, mobility, and conductivity, as well as storage stability during 28 days at 4ºC and stability after UV irradiation. Encapsulation efficiencies of sil...

A gluten-free diet is the only available therapy for people with celiac disease (CD) and wheat allergy (WA). Given that this type of diet is difficult to implement because there is a possibility that gluten-free products could be contaminated with gluten, the aim of this paper was to examine the effect of cold plasma treatment on gluten proteins pr...
