CGTase is an enzyme: Capable of converting starch and related substrates into cyclodextrins (CDs). CD is widely used as a quality-improving agent in food products for various applications including: fixation of volatile substances, such as fragrances and spices; powderization of alcohols; solubilization of insoluble substances; and masking of unpleasant odors and bitter tastes.. amano-enzyme.jp
