Abstract
Included is the preparation of particulate coffee products with improved particle packing characteristics. Fine coffee particles having particle diameters of less than about 600 micrometers are compacted to a bulk density of from about 0.40 to about 0.70 gm/cc. The resulting coffee products have the isodensity and isobrew solid profiles as shown in FIGS. 1 and 2, respectively, where the bulk density and brew solid values for any ternary particle mixture represented on the graph increases with increased coffee fine fractions therein. The process can also be used to control or increase the bulk density of particulate coffee products thereby eliminating or reducing the need to rely upon roasting means to control bulk density. The compaction operation changes the particle morphology without rupturing the cell walls of the coffee.
