  • A nutraceutical system was encapsulated in a blend of biopolymers by spray drying.

  • The sorption isotherms of microcapsules presented a sigmoidal shape.

  • The GAB and Curie models were useful for modelling moisture sorption of microcapsules.

  • The pore radius of the microcapsules varied from 0.67 to 8.15 nm.

  • The minimum integral entropy is in the range of 0.19-0.37 of aW.
