Content expressed as means ± standard deviation. Means with different letters within a row (, , , ) differ significantly (; significance of difference between measuring times). Means with different letters within a column (, ) differ significantly (; significance of difference between shredding types). Thin, 0.5 mm slices; thick, 2 mm slices.
