Abstract
Background. Carbohydrate-rich foods, such as breakfast products, snacks and biscuits because of its nutritional or sensory qualities are an inherent part of human diet. However, their production might contribute to the formation of acrylamide, 3-monochloropropane-1,2-diol (3-MCPD) and its esters and glycidyl esters. Objective. The aim of this work was to assess the levels of acrylamide, free and bound 3-MCPD and glycidyl esters in selected carbohydrate-rich, thermal processed products, present on the market in Poland in 2016-2017. Material and Methods. The survey involved 60 samples of snacks, breakfast products and biscuits. Acrylamide and free 3-MCPD was determined using modified QuEChERS approach. Analysis of 3-MCPD and glycidyl esters was based on the acid-catalysed method of sample preparation, derivatisation with PBA and GC-MS analysis. Results. Free 3-MCPD contents were within the values of 9.3-63.3 μg kg-1, with the highest mean content for muesli (33.3 μg kg-1), and the lowest for baby biscuits (11.7 μg kg-1). The levels of bound 3-MCPD were higher (from 9.3 μg kg-1 to 1500 μg kg-1). The highest average content was observed for sugar free biscuits (599 μg kg-1), whereas the lowest for breakfast cereals (50.2 μg kg-1). Glycidyl esters were detected only in four samples with the highest content at the level of 28.8 μg kg-1. The acrylamide levels varied from 195 to 1352 μg kg-1, with the highest content for organic biscuit samples (913 μg kg-1), and the lowest for muesli (348 μg kg-1). Conclusions. Regular consumption of popular snacks such as potato chips, crackers and biscuits may result in risk to human health as the effect of high content of acrylamide or 3-MCPD. Due to a high level of these contaminants detected in some type of breakfast products, and products targeted for children, its consumption should be restricted, especially in younger population groups.
