ABSTRACT:
A freeze-dried soluble coffee product in the form of particles or granules and having a microporous structure is prepared by prechilling a metal plate in a liquid refrigerant, immersing the plate in aqueous extract of coffee solids, reimmersing the plate in a liquid refrigerant, removing the frozen particles in the form of flakes from the plate, grinding and freeze-drying the flakes to produce frozen extract particles with reduced entrainment losses. The product so prepared has a unique porosity and is capable of sorbing, retaining and releasing volatile aromatic compounds.
