Description

α-Cyclodextringlucosyltransferase (CAS NO 9030-09-5) is a specialized enzyme that catalyzes the transglycosylation reaction for the production of α-cyclodextrins from starch. This biocatalyst is critical for achieving high-purity, food-grade and pharmaceutical-grade cyclic oligosaccharides with precise ring sizes. It is an essential processing aid for manufacturers in the food, pharmaceutical, and nutraceutical industries seeking to enhance product stability, solubility, and bioavailability through molecular encapsulation.

Application

• Cyclodextrin Production: Primary industrial use for the enzymatic synthesis of α-cyclodextrin from starch or starch derivatives.
• Food & Beverage Industry: Used to produce α-cyclodextrin as a food additive for flavor protection, bitterness masking, and stabilization of sensitive compounds like vitamins and colors.
• Pharmaceutical Formulations: Enables the production of pharmaceutical-grade α-cyclodextrin, used as an excipient to improve the solubility, stability, and bioavailability of active pharmaceutical ingredients (APIs).
• Nutraceutical & Supplement Manufacturing: Facilitates the encapsulation of unstable bioactive compounds, probiotics, and oils to enhance shelf-life and efficacy.
• Chemical Synthesis: Serves as a biocatalyst in organic synthesis for regioselective glycosylation reactions.
• Research & Development: A key reagent in biochemical and enzymatic research for studying carbohydrate metabolism and developing new enzymatic processes.
