Determination of phenolics and proteins causing sediment formation in pomegranate juice using “Tannase+Lactonase” and “Protease”
Türkyılmaz, Meltem; Hamzaoğlu, Fatmagül; Özkan, Mehmet (Elsevier, 2024)In this study, pomegranate juice (PJ) was treated with “tannase+lactonase [human-derived (H-PON-1) or rabbit-derived (R-PON-1)]” or “protease [aspartic protease (AP) or cysteine protease (CP)].” After treatment, effects ... -
Enhancement of colour density and anthocyanin stability in pomegranate juice against 5-hydroxymethylfurfural at different concentrations by amino acid copigmentation during storage
Türkyılmaz, Meltem; Hamzaoğlu, Fatmagül; Çiftci, Rümeysa Betül Arı; Özkan, Mehmet (Elsevier, 2024)This study investigated the effect of amino acid [aspartic acid (Asp), phenylalanine (Phe) and valine (Val)] copigmentation on pomegranate juice (PJ) anthocyanins in the presence of 5-hydroxymethylfurfural (HMF) at different ... -
Increase in colour stability of pomegranate juice against 5-hydroxymethylfurfural (HMF) through copigmentation with phenolic acids
Türkyılmaz, Meltem; Hamzaoğlu, Fatmagül; Çiftçi, Rümeysa Betül Arı; Özkan, Mehmet (Wiley, 2023)BACKGROUNDAnthocyanins are responsible for both attractive colour of pomegranate juice (PJ) and its health-promoting effects against cancer and coronary heart disease. However, 5-hydroxymethylfurfural (HMF) at some ... -
A new enzymatic clarification method for pomegranate juice: Removal of defects and improvement of quality by tannase, lactonase and papain
Türkyılmaz, Meltem; Hamzaoğlu, Fatmagül; Özkan, Mehmet (Elsevier, 2024)Effects of clarification with "tannase," "tannase+lactonase," "papain," "aspartic protease" and "tannase+lactonase+papain" on defects (turbidity, sediment and color loss) and important constituents (phenolics, anthocyanins, ...
