Hydroxymethylfurfural (HMF; 5-hydroxymethyl-2-furaldehyde) is present in a range of foods containing carbohydrates in an acidic environment. In this work, HMF was determined by the HPLC method in six food commodity groups. The HMF content in tomato puree (n = 11) ranged between 2.8--84.2 mg/kg; in ketchups (n = 15) it ranged between 0.8--189.8 mg/kg; in syrups (n = 13) and juices (n = 12), it ranged between 0.0--27.3 mg/kg; in jams (n = 12) between 4.5--159.6 mg/kg, and in fruit baby foods (n = 13), the content of HMF amounted to 2.1-- 9.8 mg/kg. The to-tal daily exposure to HMF from six investigated food commodity groups for an average person in the Czech Republic may thus amount to 1.11 mg/person/day, of which the exposure to ketchups is the highest (up to 0.54 mg/person/day).
