The highly water-soluble acrylamide is easily extracted from
the ground coffee to the liquid phase of the beverage (Andrzejewski
et al., 2004). Some studies reporting acrylamide levels in common
coffee beverages (as plunger pot and filtered coffee) have
already been published, reporting values between 2 and 25 lg/L.
The acrylamide concentrations reported in this study, for standard
espressos (30 mL), are higher than those reported by other authors
for other coffee brews.
