The Comparative Amount of Acrylamide in Tahdig Prepared with the Most Common Edible Liquid and Solid Oils

Abstract

Background: Due to the heating of amino acids with edible oils to high temperatures, different amounts of acrylamide are produced. Objective: The purpose of this study was to compare the level of acrylamide in the tahdig of bread and tahdig of potato prepared with the common liquid and solid edible oils, including sunflower, corn, canola, frying oil and solid oils. Methods: The tahdig of bread and potato was prepared under the same temperature and time with different oils. Acrylamide isolation was performed on a solid-phase extraction (SPE) cartridge and acrylamide was determined using High-performance liquid chromatography (HPLC). Results: The highest amount of acrylamide was obtained with sunflower oil in the tahdig of potato (194.091 mg/Kg) and the lowest amount of acrylamide was obtained with solid oil in the tahdig of bread (48.54 mg/Kg). For all the oils, the acrylamide content of the tahdig of potato was higher than bread. Conclusion: This study clearly demonstrated the involvement of the kind of oils in the formation of acrylamide in the tahdig of bread.
