Beta-chitin complex and method for producing the same

摘要

The present invention provides a beta-chitin complex composed of an inclusion compound formed by using a beta-chitin as a host and a guest compound which is a compound having a functional group that can form a hydrogen bond with a hydroxyl group and/or an amide group of the beta-chitin and having a melting point of at least 60° C. The beta-chitin complex is prepared by a method comprising the step of heating a guest compound to its melting point or higher to prepare a melt of the guest compound and the step of immersing an anhydrous beta-chitin in this melt, or a method comprising the step of dissolving or suspending a guest compound in a solvent to prepare a guest carrier solution and the step of immersing a beta-chitin in the guest carrier solution.
