CNC or sodium TPP was crosslinked with chitosan (CH) to form microcapsules. Blueberry anthocyanin (ACN) extracts were loaded in CH-CNC and CH-TPP microcapsules. CH-CNC microcapsules had better encapsulation efficiency than CNC-TPP ones. CH-CNC microcapsules provided better ACN stability than CNC-TPP ones. CNC functioned as a filler in CH matrix to form rigid, stable microcapsules.
