Abstract:
A process for enabling the production of a particulate composition containing crystalline trehalose dihydrate is provided. Including allowing an α-glycosyltrehalose-forming enzyme to act on liquefied starch derived from a microorganism of the genus  Arthrobacter  and a trehalose-releasing enzyme derived from a microorganism of the genus  Arthrobacter  along with a starch debranching enzyme and a cyclomaltodextrin glucanotransferase; allowing glucoamylase to act on the resulting mixture to obtain a saccharide solution containing α,α-trehalose; precipitating crystalline α,α-trehalose dihydrate from the above saccharide solution; collecting the precipitated crystalline α,α-trehalose dihydrate by a centrifuge; and ageing and drying the collected crystals. Cyclomaltodextrin glucanotransferase derived from a microorganism of the genus  Paenibacillus  or a mutant enzyme thereof is used to increase the α,α-trehalose content in the saccharide solution to over 86.0% by weight, on a dry solid basis, without passing through a fractionation step by column chromatography.

Claim (Index 10):
The process of  claim 6 , wherein said controlled cooling method is a cooling method where the liquid temperature \u201cT\u201d at the time \u201ct\u201d is basically expressed by the formula:\n T=T 0 \u2212( T 0 \u2212T f )( t /\u03c4) 3 , \n wherein \u201c\u03c4\u201d is the operation time established for a crystallization step, \u201cT 0 \u201d is the liquid temperature at the initiation of crystallization, and \u201cT f \u201d is the targeted liquid temperature at the termination of crystallization; and \n wherein said semi-controlled cooling method is a cooling method, where the liquid temperature \u201cT\u201d is allowed to linearly or stepwisely decrease against the time \u201ct\u201d in order to keep the variation (T 0 \u2212T m ) of the liquid temperature \u201cT\u201d at the point of \u201ct=\u03c4/2\u201d to be at least 5% but less than 50% of the total temperature change (T 0 \u2212T f ), and wherein \u201cTm\u201d is the liquid temperature at time \u201ct=\u03c4/2\u201d.
