Samples with a common letter are not significantly different (p>0.05): lower case letters compare the first ten samples of the first column (from C1 to W2), upper case letters compare the last nine samples of the first column (from A2 to WP2); C=control gel (without fibre), A=apple, B=bamboo, P=psyllium and W=wheat fibre
