Degradation kinetics of anthocyanins in acerola pulp: Comparison between ohmic and conventional heat treatment

► Anthocyanin degradation kinetics during ohmic and conventional heating was evaluated. ► The rate constants of the first-order model ranged from 5.9 to 19.7 × 10−3 min−1. ► Both heating technologies showed activation energy of 74.8 kJ mol−1. ► All thermodynamic parameters were similar for ohmic and conventional heating. ► The results indicate similar mechanisms of degradation during both thermal treatments.
