WR—untreated or whole residue; CR—crushed residue; FR—residue in the form of foam; TPC—total phenolic compounds (mg of GAE/100 g dry basis); TF—total flavonoids (mg/100 g dry basis); TA—total anthocyanins (mg 100/g dry basis); TB—total betalains (betaxanthins + betacyanins) (mg/100 g dry basis); Betax.—betaxanthins (mg/100 g dry basis); Betac.—betacyanins (mg/100 g dry basis). The values are means ± standard deviation of the determination in quadruplicate. Means with the same letter in the same column do not differ significantly using a Tukey test (p < 0.05).
