Abstract:In the exploration of novel food delivery systems，protection of the active components has always been the focus. Cyclodextrin-based metal-organic frameworks （CD-MOFs）have high porosity and high specific surface areas，similar to traditional metal organic frameworks.CD-MOFs exhibit unique encapsulation ability，outstanding biocompatibility， and modifiable functionalization for the encapsulation of active components. This article introduced the structural characteristics， preparation methods， and application status of CD-MOFs. In view of the existing problems in current research，suggestions for the future direction of studies on cyclodextrin metal organic frameworks were proposed.
