during thermal treatments for 10 min, AAO in broccoli florets and stalks is stable until around 50°C. A 10 min thermal treatment at 80°C almost completely inactivates AAO. AAO inactivation is irreversible since no increase in activity is observed when extracts of thermal treated broccoli are stored at 4°C for 24 h |
