ANGEL α-Cyclodextrin glucanotransferase catalyzes the conversion of starch or other α-1,4-glucans to cyclodextrin.


ANGEL α-Cyclodextrin glucanotransferase is a biocatalyst: catalyzes the conversion of starch to cyclodextrin; has a unique role in VC carbohydrate derivatives、coupling sugar biosynthesis and modification of stevia.


α-Cyclodextrin glucanotransferase can be used for starch liquefaction and conversion of liquefied slurry to produced CDs.We recommend an addition of about 5 units/g of dry starch for liquefaction at 70℃with a 15% starch slurry, then use 5 unitsα-Cyclodextrin glucanotransferase per gram of dry starch at 30℃for 20hr.
