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...

In this paper, the influence of process parameters on the morphological properties of fine precipitated hydrate was examined. The research was conducted with the aim of synthesizing fine precipitated aluminum hydroxide from the aluminate solution obtained by the Bayer process. Fine precipitated hydrates obtained in this way are mostly used in the n...

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...

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...
