Dietary Risk Assessment of Acrylamide in School Canteen Snacks among Primary School Students in Alexandria Governorate

Abstract

Abstract BACKGROUND: Acrylamide (AA) is considered as a carcinogenic and genotoxic food contaminant produced in carbohydrate-rich foods Canteen snacks available in school are among these carbohydrate-rich foods. The paper investigates the risk associated with consuming acrylamide rich canteen snacks. AIM: The aim of the work was to study the dietary risk of acrylamide in school canteen snacks among primary school students and to determine the concentration of AA in different snacks METHODS: The level of AA was detected in 73 samples for 16 different canteen snacks sold at school canteens. Samples were collected randomly from the canteens of primary schools in Alexandria city. All samples were extracted and cleaned-up then analyzed using HPLC techniques. A food frequency questionnaire was designed to determine the frequency and amount of consumption of different canteen snacks among primary school students during school day. The data was collected from six different primary schools in Alexandria city (3 public and 3 private schools). All interviewed school students (466 student) were weighted for the calculation of dietary exposure of AA during school day. RESULTS: The results showed that, the average and the 95th percentile of acrylamide exposure were 1.4 and 4 μgkg−1 BWsd−1, respectively. There is a statistically significant difference between dietary exposure to AA between private schools and public schools. The estimated margin of exposure (MOE) calculated from the average acrylamide exposure was 128 and 221 and from 95th percentile was 45 and 77, based on BDML10 values 0.18 mgkg−1 BWd−1 and 0.31 mgkg−1 BWd−1. With the highest risk calculated in schools offering fried foods prepared in school canteen. CONCLUSION: Dietary exposure to AA from canteen snacks among primary school students in Alexandria city is considered as a health concern according to the definition of the WHO, where the calculated MOE values were very close to the values set by the JECFA committee (45-310) for health problems of concern.
