The present invention aims to provide a novel glycosyl hesperetin, which is significantly reduced in miscellaneous tastes characteristic of conventional products containing glycosyl hesperetin, and a method for producing the same and uses thereof; and the objects are solved by providing a glycosyl hesperetin which comprises glycosyl hesperetin in an amount of 90% or more by mass but less than 100% by mass, on a dry solid basis, but it does not substantially contain furfural, and a method for producing the same and uses thereof.

Glycosyl hesperetin and process for producing the same and uses thereof

Disclosed is a recombinant thermostable enzyme which has a molecular weight of about 54,000-64,000 daltons and a pI of about 5.6-6.6, and releases trehalose from non-reducing saccharides having a trehalose structure as an end unit and a degree of glucose polymerization of at least 3. The enzyme has a satisfactorily-high thermostability, i.e. it is not substantially inactivated even when incubated in an aqueous solution (pH 7.0) at 85&deg; C. for 60 min, and this facilitates the production of trehalose on an industrial scale and in a satisfactorily-high yield.
