Such a decrease occurs when the rate of degradation exceeds the rate of formation, probably due to the reaction of acrylamide with other reactive species present in the coffee (Biedermann, Biedermann-Brem, Noti, & Grob, 2002). Recently, Pastoriza, Rufián-Henares, and Morales (2012) stated that acrylamide may react with coffee melanoidins during roasting, leading to a net decrease in acrylamide content.).
