Process for producing a particulate composition comprising crystalline alpha, alpha-trehalose di-hydrate |
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. |
