| Abstract/Summary |
The selected quality and authenticity markers of tomato ketchup were determined in 3 sets of ketchup. The qualitative criteria (colour, pH, hydroxymethylfurfural) were evaluated in commercial samples of ketchup. Authentic markers (formol number, citric and malic acid, pyrrolid-5-one-2-carboxylic acid, and minerals K+, Mg2+, Ca2+) were determined in model prepared samples and real samples with known natural tomato soluble solids content of the same producer.
