Ceaban, Dmitrii | Pushoy, Vladimir
In this study we aim to evaluate the potential of local Moldovan fruits , namely quince ( Muscat, Port), pear (Conference, Victoria) , apple (Golden, Jonathan) as sources of beneficial and bioactive compounds (polyphenols and antioxidants), studying the effect of different extraction solvents. The samples were followed by extraction with ethanol in different concentrations (25%, 50%, 75% ). They were taken both from the pulp and from the surface of the products. The results show that the polyphenolic content is higher in the samples extracted in the concentration of 75% ethanol and taken from the surface of the product. This correlation is positive for quince and pear, and negative for apple, because the highest polyphenolic content in apples was found in the concentration of 25% ethanol.
