Survey for acrylamide in processed foods from Korean market and individual exposure estimation using a non-parametric probabilistic model

ABSTRACT:

Acrylamide, a known carcinogen, is formed during preparation of food containing reducing sugar and asparagine. Because acrylamide exposure of the population is primarily through food, the maximum levels of acrylamide in food were set by the European Commission in 2017. Moreover, in the 2016 Korean Total Diet study, acrylamide showed the lowest margin of exposure among 23 food-processing-related chemicals, necessitating risk reduction options. Therefore, the objective of this study was to determine the variation of acrylamide content in different food items and identify the food categories, to provide options for risk management. Acrylamide was analysed using high-performance liquid chromatography coupled with tandem mass spectrometry in more than 1,000 processed food items. To estimate acrylamide exposure, the analytical data obtained herein and the food consumption data of Korean National Health and Nutrition Examination Survey from 2013 to 2017 were used. A non-parametric technique of a probabilistic model was used for exposure estimation. Confectioneries (here this category includes potato and similar savoury snacks) contained a wide range of acrylamide content. Particularly, the highest acrylamide content was detected in a tea made of Jerusalem artichoke. The presence of acrylamide in turmeric along with the Jerusalem artichoke was reported in this study for the first time. The main contributors of dietary acrylamide exposure were confectioneries for youths aged 3-18 years and coffee for adults aged 19-80 years. Therefore, risk management in confectionery and coffee could help reduce acrylamide exposure for Koreans. In addition, the mitigation strategies for food containing high acrylamide content, such as Jerusalem artichoke tea, are needed to reduce acrylamide exposure to loyal consumers.
