Acrylamide in thermal-processed carbohydrate-rich foods from Chinese market.

Acrylamide content in food market in China was determined with the goal to evaluate related health concern. In this survey, products of rice, potato corn, wheat as well as dried fruit slices and instant foods were analysed. All these types of thermal-processed carbohydrate-rich foods were frequently consumed in China. They were purchased from markets in Zhejiang province and analysed using a liquid chromatography tandem/mass spectrometry method. Acrylamide was detected in 94.3% of 105 investigated samples, ranging from 10 to 3649 μg/kg with an average value of 231 μg/kg and a median of 114 μg/kg. In this study, high levels were found in potato products (564 ± 285 μg/kg), corn products (524 ± 187 μg/kg) and instant foods (180 ± 35 μg/kg) while low levels were measured in rice products (82 ± 17 μg/kg), wheat products (96 ± 29 μg/kg) and dried fruit slices (83 ± 13 μg/kg).
