A survey on the occurrence of acrylamide (AA) in roasted coffee, barley, and potato crisps was carried out using an intra-lab validated liquid chromatography (LC)-MS (mass spectrometry)/MS method. Over the years 2015-2016, 66 samples of coffee, 22 of roasted barley, and 22 of potato crisps were collected from retail outlets in Italy. AA was detected in almost all samples. In roasted coffee, the level exceeded 450 µg kg, the limit recommended by the European Commission (EC), in 36.4% of the samples. In roasted barley, mean contamination was slightly lower than in coffee and no sample exceeded the EC limit of 2000 µg kg. The AA contamination in potato crisps was remarkable. A percentage of 36.4 (n = 8) showed a value higher than the EC limit of 1000 µg kg. Considering the average consumption of coffee and potato crisps by Italian people, AA exposure is significant and should be decreased.
采用实验室内部验证的液相色谱（LC）-质谱（MS）/质谱法，对烘焙咖啡、大麦和薯片丙烯酰胺（AA）的含量进行了调查。在2015年至2016年期间，从意大利零售商店收集了66份咖啡样品、22份烘焙大麦样品和22份薯片样品。几乎在所有样品中都检测到了AA。在烘焙咖啡中，36.4%的样品中AA含量超过了欧盟委员会（EC）建议的450μg/kg限值。在烘焙大麦中，平均污染水平略低于咖啡，且没有样品超过EC规定的2000μg/kg限值。薯片中的AA污染较为显著。36.4%（n = 8）的样品显示其含量高于EC规定的1000μg/kg限值。考虑到意大利人咖啡和薯片的平均消费量，AA的摄入量很大，应该降低。
