Abstract
A method of producing coffee particles containing entrapped aroma. Soluble coffee solids and up to 10% by weight water are introduced into a heating and mixing zone and to raise the temperature to about 85.degree. C. to about 130.degree. C. to form a molten mass. Aroma-containing substrate is introduced into the molten mass to form a molten mixture containing a gas under a pressure of about 2.0 MPa to about 7.0 MPa. The molten mixture is extruded into a pressure zone in which the pressure is greater than the pressure of the gas in the molten mixture and the molten mixture is retained in the pressure zone until it solidifies to form a hardened glass. The hardened glass is ground into coffee particles of size of about 0.5 mm to 3 mm.
