Abstract
The present invention relates to a process to recover beneficial coffee volatiles such as diacetyl and acetaldehyde from an aroma stream generated by the thermal hydrolysis of spent grounds. The aroma stream is passed over a bed of a non-polar microporous adsorbent and effluent is collected until breakthrough of furfural is detected. The invention also relates to the composition of the recovered/purified coffee aroma and to soluble coffee products containing the coffee aroma.
