PROBLEM TO BE SOLVED: To produce a readily handleable erythritol powder, easily mixable with other food materials and having a smooth texture when eaten without consolidating by blending erythritol having a specific particle diameter in a prescribed proportion and reducing the moisture content in the powder to a prescribed value or below. SOLUTION: This erythritol crystal contains >=98wt.% crystal of 250μm undersize and <2wt.% crystal of 250μm oversize and has the moisture content thereof reduced to <=0.04wt.%. The erythritol crystal without consolidating is prepared by affording an erythritol crystal, containing >=97wt.% crystal having a particle size of 1000μm undersize to 360μm oversize and <3wt.% crystal of 360μm undersize and having the moisture content thereof reduced to <=2wt.% (in the first pulverizing and drying step) and further providing the erythritol crystal, containing >=98wt.% crystal of 250μm undersize and <2wt.% crystal of 250μm oversize and having the moisture content thereof reduced to s 0.04wt.% (in the second pulverizing and drying step). The second pulverizing and drying step is preferably carried out at 20-110 deg.C at <=65% relative humidity. The erythritol is useful as a sweetener.
