Table 2 shows the influence of each coffee species (arabica and
robusta) on the acrylamide content of EC. Although the samples
were medium roasted by a standard procedure, the organic roast
loss was different within each species, as a consequence of the
beans intrinsic characteristics.
Significantly higher amounts (p < 0.001) of acrylamide were
found in robusta samples, with levels per cup (30 mL) ranging between
1.71 and 2.92 lg. For arabica coffee, the levels were half
lower, varying from 0.87 and 1.52 lg/EC.
