Determination of Acrylamide and ۵-hydroxymethyl-۲-furfural (HMF) Levels and Related Parameters in Turkish Pekmez (A Traditional Fruit Product)

Background: Pekmez is an important fruit-based food of Turkish culinary culture. The aim of this study is to determine the levels of acrylamide (AA), ۵-hydroxymethyl-۲-furfural (HMF) and other selected parameters in grape, mulberry and carob Pekmez. Methods: AA and HMF were analyzed by Liquid Chromatography and High Performance Liquid Chromatography, respectively. Also, glucose, fructose, pH, protein, total phenolic, and color (L*a*b*) were analyzed. The analyses were done by IBM SPSS Statistics ۲۶ software. Results: The average AA, HMF, glucose, fructose, total reducing sugar, pH, protein, total phenolic, and colour (L*a*b*) values of Pekmez were ۳۰۲ µg/kg, ۲۵.۷ mg/kg, ۱۳.۲%, ۱۴.۰%, ۲۷.۲%, ۵.۲۷, ۱.۱۶%, ۴.۶۴ mg GAE/g, and ۴.۸۳*۵.۶۰*۱.۵۲, respectively. AA indicates a moderate positive linear correlation with HMF, protein, total phenolic; whereas AA indicates a moderate negative linear correlation with glucose, fructose, total reducing sugar, pH, and L*a*b. Conclusion: It is presumed that heat treatment is a determinant in AA and HMF formulation. DOI: ۱۰.۱۸۵۰۲/jfqhc.۸.۴.۸۲۵۸
