Title:
METHOD FOR REGENERATING TREATMENT OF CYCLODEXTRIN
Document Type and Number:
Japanese Patent JP3154234
Kind Code:
B2
Abstract:

PURPOSE: To safely carry out the regenerating treatment at a low cost without using special equipment and a special reagent by adding water or an oil and a fat to cyclodextrin adsorbing a fat-soluble substance, passing the substance into an oily phase and the cyclodextrin to an aqueous phase and individually recovering both.
CONSTITUTION: This method for the regenerating treatment of cyclodextrin is to add water and an oil and a fat to cyclodextrin including or adsorbing a fat-soluble substance (e.g. cholesterol or a cholesterol ester), stir or heat-treat the resultant mixture, pass the cyclodextrin into an oily phase and the cyclodextrin into an aqueous phase and individually recover each. The amount of the water used is 5-300 times based on the weight of the cyclodextrin including or adsorbing the fat-soluble substance. The oil and fat are a vegetable or an animal oil and fat, a processed product or a mixture thereof and added in an amount of at least 20wt.% based on the weight of the cyclodextrin. The heating is carried out at 85-100°C for 5-40min. The feat soluble substance in the regenerated cyclodextrin is removed ≥90%.
