An object of the present invention is to provide a particulate composition containing crystalline &#x3b1;,&#x3b1;-trehalose dihydrate, having an advantageous emulsifying ability. The above object is solved by providing a particulate composition comprising crystalline &#x3b1;,&#x3b1;-trehalose dihydrate, which consists of particles containing &#x3b1;,&#x3b1;-trehalose and maltose and/or maltotriose, wherein said particulate composition contains &#x3b1;,&#x3b1;-trehalose in an amount of 70% by weight or higher but 90% by weight or lower, on a dry solid basis; and maltose and/or maltotriose in a total amount of 3% by weight or higher, on a dry solid basis; and has a degree of crystallinity for crystalline &#x3b1;,&#x3b1;-trehalose dihydrate of 25% or higher but less than 90%, when calculated based on its powder X-ray diffraction profile.
