<p>Rigid containers, such as metal cans, for use in hermetically packaging roasted coffee products are coated internally with an aroma solvent (e.g. glycerides, waxes, silicones, etc.) which is effective to dissolve and partition a broad range of aromatics. This effects an aroma partition between the headspace in the sealed, coffee-containing can and the coating which retards staling and/or oxidation of the coffee aroma within the sealed can. The pick-up of aroma by the coating may also increase the amount of aroma retention within the opened container during an extended in-use period.</p> |
