Total monomeric anthocyanins and L-ascorbic acid followed first-order kinetics, while a zero-order kinetic model was determined for the degradation of total phenolics. The first-order reaction was also described for the color loss in terms of Hunter a, b and C values. The activation energies for the degradation of raspberry anthocyanins, L-ascorbic acid and total phenolics were 49.3, 15.7 and 32.2 kJ/mol, respectively. Higher activation energies (49.0-75.5 kJ/mol) found for color loss indicates, this reaction is more sensitive to the temperature elevations than the other reactions.eninfo:eu-repo/semantics/closedAccessArticle10.1111/jfpp.120023815515572-s2.0-84897959883Q2WOS:000336258900060Q3
