The fresh bread samples, after equilibrating for 2 h at room temperature, were placed in sealed polyethylene bags and stored for 7 days, the losses of L. rhamnosus GG through the entire storage period are shown in Fig. 6. The viability loss of three out of four bread systems (ALG@60, ALG/WPC@60 and ALG@180) exhibited a similar pattern as a function of storage time.
