Abstract

Egyptian Amhat dates in khalal stage were treated by differnt tempeatures (40,60,65,70 and 80°C) for different periods. Treatments at 65°C and 70°C led to decrease total phenols and low molecular weight tannins which are responsible of astringent taste. Organoleptic analysis revealed that treating khalal dates at 65°C and 70°C led to the best quality of ripening dates (color, taste and flavor).
