Determination of acrylamide in processed foodstuffs in Japan

Abstract

Acrylamide in processed foodstuffs (32 items, 63 products) sold in supermarkets in Japan was determined by LC-MS/MS and GC-MS methods. The limit of detection and limit of quantification were 0.2 and 0.8 ng/ml, respectively, for the LC-MS/MS method, and those were 12 and 40 ng/ml, respectively, as a brominated derivative for the GC-MS method. Repeatability, given as RSD (%), of the LC-MS/ MS method was <5%, and that of the GC-MS was <15%. High correlation (r2=0.946) was observed between values obtained by the two methods. The acrylamide level was 439-1870 μg/kg for potato crisps, 15-3540 μg/kg for fried snacks, 17-303 μg/kg for rice crackers, and 4-54 μg/kg for instant noodles and won-tons.
