Open the CIPO recordAbstract From the Canadian patent
A process for 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 aromatised gas containing aroma components. The aroma components are then collected from the aromatised 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 flavour and contains higher levels of furans and diketones.

Why it's free to use
- Filed February 4, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 4, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 4, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
