Figure S1. Proton transfer reaction mass spectrometry (PTR-MS) spectra of Bellstar (a, b) and Legacy (c, d) broccoli after storage at 23 °C. Concentrations of m/z 33 (methanol), 45 (acetaldehyde) and 49 (methanethiol) are indicated.

Figure S2. Partial least square regression 1 (PLSR1) score and correlation plots for Bellstar broccoli lipoxygenase (LOX) (a, b) and peroxidase (POD) (c, d) and for Legacy broccoli LOX (e, f).

Figure S3. Change in (a) a* value, (b) b* value, (c) methanol concentration and (d) acetaldehyde concentration of broccoli stored for 7 days at 23 °C in dark (n = 5, mean ± SD).
