Abstract:The aim of the current work was to compare the (poly)phenol profile (free, soluble-conjugate, and insoluble-bound) and antioxidant activity of date palm seed flour using different extraction methods (conventional vs. ultrasound-assisted extraction [UAE]) and to determine the most critical variables in the extraction of (poly)phenols through UAE using the Plackett–Burman design experiment. Using the Plackett–Burman design, seven factors, namely, ethanol concentration, liquid:solid ratio (mL/g), sonotrode, ampli… Show more
