Source and Preparation | Cyclodextrin is prepared by enzymolysis of amylase using special bacteria. The first step in the preparation of cyclodextrin (food grade), the starch paste is prepared by cyclodextrin glucose-transferase (CGTase, EC 2.4.1.19, CAS 9030-09-5) under controlled pH and temperature conditions. CGTase is derived from recombinant Escherichia coli. CGTase gene of Bacillus occitorella was latent. Alphacyclodextrin is precipitated by the addition of 1-decyl alcohol in an enzymatic reaction. Purification is obtained by solubility in water and reprecipitation. The added 1-decanol was separated from afacyclodextrin by reanalysis and steam distillation. Finally, afacyclodextrin was obtained by crystallization and white powder purity ≥ 98.0%. |
