This paper presents kinds of extraction and cross-flow filtration of composition of 46 healthful and aromatic herbs, 8 fruits and fungi Ganoderma lucidum. Those extracts are part of Bitter 55, which have significant antioxidant capacity. Antioxidative activities of plant extracts have been determined by DPPH test using method of Blois. Bitter 55 which was kept at the green bottle in the dark has EC50 = 141.07 μl/ml and it was stable during 150 days.

Change of anthocyanins content during raspberry extraction

Faculty of Agriculture, Belgrade-Zemun (1,2,3,4)


Change in anthocyanins content under different conditions of extraction enzymatic maceration and heat treatment of two raspberry cultivars (Villamette and Meeker) was determined. Experiments were carried out on a laboratory hydraulic extractor. During extraction commercial operating conditions were emulated using a "Bucher" extractor (pressure 180-200 bar 1-3 pulp shakings).

The methods for estimating Fe, Mn and Zn solubility in smonitzas over Serbia (ten localities) used as fields and meadows, were studied in this paper. The total contents of these elements were found to be nearly equal to their mean values in the world soils. Regarding their availability, investigated smonitzas were found to be well supplied with manganese and, for the majority of samples, with iron.
