Abstract

Grinder gas aroma evolved from the comminution or fracturing of freshly roasted coffee beans is stabilized by condensing the gas and adding an oxygen scavenger to the condensate. This condensate is then briefly contacted and extracted with a fluorinated-chlorinated hydrocarbon to remove harsh aroma compounds and then with a mixture of non-polar and polar solvents in order to extract desirable aromatics. This extract is stable at freezer temperatures and can be used to aromatize coffee or coffee-like products.
