EXPSURE TO ACRYLAIDE FROM HOME-COOKED FOOD: FRIED POTOES (RÖSTI) IN SWTZERLAND AS AN EXPLE

Abstract

There is a significant lack of data on acrylamide in food which is prepared domestically, as obtaining samples of food cooked in people’s homes is more complex than taking samples from shops. Rösti is a fried potato dish, which can be a significant contributor to acrylamide exposure, particularly in the German speaking areas of Switzerland. A set of 71 samples was collected from people who cooked the dish at home. The average acrylamide content was 709 µg/kg. Based on a food frequency questionnaire and on a Swiss national food survey the results enabled the determination of the exposure of the population to acrylamide through home-made rösti. The values for an exposure estimate to acrylamide from rösti are 7.8 µg/day for the whole population (including rösti eaters and non-eaters) and 27.2 µg/day for predominantly rösti consumers participating in this study.
