An object of the present invention is to provide a crystalline saccharide having novel physical properties, a preparation and uses thereof. The present invention solves the above objects by providing a porous crystalline saccharide having a number of pores, a process for producing the same, comprising the step of keeping hydrous crystalline saccharide at an ambient temperature or higher in an organic solvent for the dehydration, and the use thereof.

Porous crystalline saccharide, its preparation and uses

Objects of the present invention are to provide a novel anhydrous crystalline &#x3b2;-maltose, its preparation and uses. The present invention attains the above objects by providing an anhydrous crystalline &#x3b2;-maltose with a melting point of 154 to 159&#xb0; C.; a process for producing the same, comprising a step of keeping hydrous crystalline &#x3b2;-maltose in an organic solvent at an ambient temperature or higher for the dehydration; and uses of the same.

Anhydrous crystalline &#x3b2;-maltose, its preparation and uses

Disclosed are a crystalline trehalose dehydrate which has an elongated crystalline structure with a proportion of the length in the c axis to that in the b axis less than 2.0, its preparation and uses. The crystal has insubstantial hygroscopicity and solidification, and satisfactory stability, free-flowing ability, and handleability; it can be easily processed without fracture in the drying and sieving steps.
