¹ T0 = 5 d ageing, T1 = 30 d post ageing; T2 = 60 d post ageing. Means with different letters within a row (post ageing time) differ significantly for p < 0.05 (small) or p < 0.01 (capital) while different symbols within a column indicate that means differ significantly for p < 0.01 (**) or p < 0.001 (***).
