Quantification of total proteins (A), antioxidant activity (B) and anti-tyrosinase activity (C) in molecular weight protein fractions obtained after sequential centrifugation with different cut-off membranes of R1 batch 5, 2 L Pancreatin and Papain digestates. Different letters indicate statistically significant difference among the same assay (protein quantification, antioxidant activity, anti-tyrosinase activity) determined by one way ANOVA followed by post-hoc Tuckey’s multiple pairwise comparison (p < 0.03). AA, ascorbic acid; KA, kojic acid. Data are the mean ± SD (n = 2).
