T1 = control, T2 = KMS-treated pomace ball, T3 = KS-treated pomace ball, T4 = KMS + KS-treated pomace ball. All values represent the means of triplicate determinations ± standard deviation (SD). Means within the same column followed by different letters (a, b) indicate statistically significant differences (p < 0.05). KMS: potassium metabisulfite; KS: potassium sorbate.
