Mean value±S.E. (N=2) in the same column with different lowercase letters show significant differences during storage (p<0.05). Mean values in the same row with different capital letters show significant differences among samples (p<0.05). Ctr 1 and 2=samples without RWP and MTG (1) and with MTG (2) as control; A5, A10 and A15=samples with 5, 10 and 15% RWP; A5+MTG, A10+MTG and A15+MTG=samples with 5, 10 and 15% RWP and 0.5 U/g MTG; RWP=reconstituted whey powder; MTG=microbial transglutaminase
