Crystalline maltitol powder less prone to consolidation, with a score of 0.6 or less in the degree of consolidation measured by a consolidation grade test method shown below. (consolidation grade test method) I. 50 g of a sample of crystalline maltitol powder are loaded into a commercially available sample bottle (150 ml maximum capacity, 4.1 cm internal mouth diameter, 5.5 cm diameter cover, and 9.5 cm total height) under an environment with a relative humidity of 50% and a temperature of 20 ° C. The bottle is tightly closed with a cap accompanied by internal and external polypropylene polyethylene caps, and a vinyl tape is subsequently provided on it to seal the boundary between the caps and the bottle. II. The sealed bottle is then loaded into a chamber equipped with a thermostat and evaluated according to the following decision criteria (1) to (3) after a period of 20 days of storage at a temperature of 20 ° C and 40 ° C repeated alternately at 12 hour intervals. Five identical samples are prepared for evaluation, and an average value of test results from these five samples is used as a degree of consolidation in the present method of consolidation grade test: (1) A score of 0 is given when the Sample powder flows completely to the mouth of the bottle and thus exhibits fluidity without adhering to the inner bottom of the sample bottle or adheres slightly to the inner bottom of the sample bottle but flows to the mouth of the bottle and thus exhibits fluidity, in the manner of tilting the sample bottle with the sample at a 90 degree angle (horizontally leveling the sample bottle held in an upright position) without giving an impact to it; (2) A score of 1 is given when the sample powder neither flows nor shows fluidity by tilting the sample bottle at a 90 degree angle but flows into the mouth of the bottle in the passage or within 1 minute after in addition to tilting the bottle at an angle of 180 degrees; and (3) A score of 2 is given when the sample powder does
