| titleOfInvention | Preparation method of gamma-cyclodextrin |
| abstract | The invention provides a preparation method of gamma-cyclodextrin, which belongs to the technical field of cyclodextrin preparation and comprises the step of reacting starch solution, gamma-cyclodextrin glucosyltransferase and an organic solvent for 2-5 hours at the temperature of 50-80 ℃ and the pH value of 6.6-7.2 to generate the gamma-cyclodextrin, and the preparation method is characterized in that 0.01-0.1g of 1-ester-3-alkyl imidazole hexafluorophosphate is added into each gram of starch in the reaction system. Experiments show that the hydrophobicity of the gamma-cyclodextrin can be obviously increased by adding the ester group functionalized ionic liquid and matching with a specific buffer solution, so that the co-precipitation of the gamma-cyclodextrin and an organic solvent is promoted, and the conversion rate of the gamma-cyclodextrin is obviously increased. |
