Abstract: ABSTRACT ULTRASOUND-ASSISTED PROCESS FOR PRODUCING DEBITTERED PALMYRA PALM SPROUT FLOUR A process for producing a debittered palmyra palm sprout flour (118) includes grinding (104) palmyra palm sprouts into a flour, contacting the flour with an aqueous solvent so that flabelliferins leach from the flour into the aqueous solvent, separating (112, 114) a solid residue from the aqueous solvent, and drying (116) the solid residue to obtain the debittered palmyra palm sprout flour (118). The contacting comprises dispersing (108) the flour in water at a flour-to-water ratio of 1:2 to form a suspension, and subjecting the suspension to ultrasonication (110) at an ultrasound amplitude of 30% to 90% for 3 to 15 minutes. The ultrasonication (110) is a non-thermal ultrasonication that generates acoustic cavitation disrupting a cell wall and tissue matrix of the flour, thereby accelerating the leaching of the flabelliferins into the water.
