Claims14
A process for aromatizing a coffee product comprising:
- a. collecting an aroma gas comprising non-condensible volatiles of coffee;
- b. admixing the aroma gas under a pressure of at least 5 kg/cm.sup.2 with a quantity of an absorbent comprising aqueous liquid and liquid edible oil under such conditions as to produce an aroma-emulsion foam;
- and
- c. contacting said aroma-emulsion foam with soluble coffee solids to incorporate aroma in said soluble coffee solids, said foam functioning to provide substantially more liquid surface area than an equal amount of unfoamed absorbent, thereby to absorb a greater volume of said aroma gas in said quantity, than would be absorbed in said amount under similar conditions.
