Abstract:
Tarhana chips are a popular traditional fermented food consumed widely in the Kahramanmaraş region of Turkey. Tarhana chips are different from many other types of fermented food in that they are produced in the form of tortilla chips. Cereal and yoghurt are the main ingredients in Tarhana chips. Aflatoxin M1 (AFM1) levels in dairy and dairy-based products are of concern for human health. To investigate AFM1 contamination, a total of 40 samples were collected from Kahramanmaraş region and AFM1 levels were determined by competitive enzyme-linked immunosorbent assay (ELISA). Furthermore, physicochemical characteristics of Tarhana chips were investigated and compared with classic fried chips in terms of nutritional value. Based on data obtained from enzyme-linked immunosorbent assay, 21 (52.5%) out of 40 samples contained AFM1 in the range 0.5-36.6 ng/kg, so AFM1 levels of all samples were below the legal limit.
