Abstract
A coffee glass is disclosed which is prepared by evaporating coffee extract to at least 45% solids and then further evaporating that extract to form as viscoelastic fluid containing above 3% to 12% water and about 88% to 97% total coffee derived solids, aromatizing and/or gasifying the fluid in a confined headspace shaping the fluid, and cooling the fluid to entrap and protect coffee aromas providing less than 20% loss of volatiles.
Claims3
A process for preparing an improved soluble coffee product comprising:
- (a) evaporating a totally coffee extract to at least 45% totally coffee-derived solids;
- (b) recovering an aroma from the totally coffee extract either prior to and/or during said evaporation;
- (c) further evaporating said totally coffee extract of at least 45% totally coffee-derived solids to a viscoelastic fluid of 91 to about 96% totally coffee-derived solids by forming a thin film of concentrated extract on a heated evaporator wall and propelling the extract down the wall in a thin film by use of rotating blades having a wall clearance of about 1/8 inch while maintaining the fluid at 80.degree. to 100.degree. C.;
- (d) collecting said fluid and pumping said fluid through a confined pressurized headspace mixing zone where coffee aroma is added and thoroughly mixed into the fluid;
- (e) rapidly cooling the mixture to trap the coffee aroma within a brittle coffee glass, the solids content of which is 100% coffee-derived with a retention of said coffee aroma of at least 80% or more of volatiles;
- and
- (f) grinding and sizing the mixture and drying if necessary to a stable moisture content of less than 6% water.
