Brightness 0–100, a* (chromaticity axis from green (−) to red (+)), b* (chromaticity axis from blue (−) to yellow (+)), ° h (hue angle (tonality)) and chroma (Chromaticity (color saturation)). A Results are expressed as g H2O/g dm. B Results are expressed as g oil/g dm. C Results are expressed as µmol glucose/g dm. The asterisk in the column reports statistically significant differences between the varieties (* p < 0.05, *** p < 0.0001)
