Abstract

The ultrasound (US) assisted extraction of bio-compounds from different fruit skins (apples, bananas and persimmons) was studied. The aqueous suspensions of skins were treated by US with different energy inputs (0.033-0.299 kW·h/kg) and total time of aqueous extraction was up to 2700 s. The ionic, Z_i, and total polyphenol, Z_p, extraction indexes of the liquid extracts were analyzed. From microscopic images the cell wall disintegration index, Z_m, was determined. Increase in US energy input caused the increase of values of Z_i, Z_p and Z_m. The correlations between extraction parameters and the disintegration index, Z_m, were discussed.

Keywords: Cell wall damage; Ionics; Polyphenols; Ultrasound-assisted extraction.
