A spray dried powder hosts the flavor molecules in cavities in the wall of the
powder particles; porous starch hosts the flavor inside the pores of the structure but there is no complete block with respect to the outside environment; maltodextrin, finally, does not form capsules and does not have a porous structure, so the liquid flavor is absorbed onto the carrier, and it is expected to be the product most susceptible to damage from heat and to volatiles loss over time
