Abstract
An aroma product resulting from the recovery of aroma components from coffee. A slurry of coffee grounds in an aqueous liquid is subjected to stripping for stripping aroma components from the slurry. The stripping is carried out using gas in a substantially counter-current manner to provide an aromatized gas containing aroma components. The aroma components are then collected from the aromatized gas. The aroma components may be added to concentrated coffee extract prior to drying of the extract. The coffee powder produced has much increased and improved aroma and flavor and contains higher levels of furans and diketones.
Claims15
An aromatized, soluble coffee powder which comprises at least about 0.60 equivalent μg/g furans and at least about 0.40 equivalent μg/g diketones and which is produced by a process including the steps of:

- stripping aroma components from the slurry using gas in a substantially counter-current manner for providing an aromatized gas containing aroma components;
- collecting the aroma components from the aromatized gas;
- extracting soluble coffee solids from coffee grounds and concentrating the extracted soluble coffee solid for providing a concentrated coffee extract;
- combining the concentrated coffee extract and the collected aroma components for providing an aromatized extract;
- and
- drying the aromatized extract for providing the aromatized coffee powder.
An aromatized, freeze-dried soluble coffee powder which comprises least about 0.60 equivalent μg/g farans and at least about 0.40 equivalent μg/g diketones.
An aromatized, soluble coffee powder which includes at least about 0.60 equivalent μg/g furans and at least about 0.40 equivalent μg/g diketones.
