A: Roasting coffee produces chemicals that, when inhaled, can cause serious, irreversible lung damage. The chemicals are released into the air in greater concentrations when the coffee is ground and during packaging. And, the chemicals build up in containers where coffee is stored after roasting.
Is there acrylamide in coffee?
Results: The highest mean acrylamide concentrations were found in coffee substitutes (818 pg/kg) followed by instant coffee (358 microg/kg) and then roasted coffee (179 microg/kg). One single cup of coffee (160 ml) delivered on average from 0.45 microg acrylamide in roasted coffee to 3.21 microg in coffee substitutes.
