Our previous study (Nguyen and Ulrich, 2014) proved that an
addition of sugar (sucrose) in the aqueous cocoa suspension successfully
improved the mechanical strength and the dissolution/
dispersal behavior of produced cocoa tablets by the freeze casting
process. A fourfold improvement (decreased) of the dispersal time
and a twofold increased tensile strength were found when sugar
was added into the aqueous phase with ratio of 20 g sugar/100 g
water. As result, a fast dissolving cocoa tablet (16 mm £, 10 mm
height) with a dispersal time of less than 1 min and a crushing
force of 34.5 N (i.e. 0.14 N/mm2 diametral tensile strength) was
obtained
