Maltodextrin, gum Arabic, modified starch and whey protein concentrate were used in concentrations of 20 g in 100 mL water, however, due to high viscosity gelatin and pea protein isolate were used at 10 g in 100 mL water. After suspending the wall materials in water, the wall material solutions were stirred with a magnetic stirrer for 1 h to hydrate. Then they were autoclaved at 121 °C for 15 min. The whey protein concentrate solution, however, did not survive the heat treatment due to denaturation at high temperature. After cooling of solutions, S. boulardii strain was added equally to the wall material solutions and stirred with a magnetic stirrer. The yeast counts of maltodextrin, gum Arabic, modified starch and whey protein concentrate solutions were 9.65 and gelatin and pea protein isolate solutions were 9.95 log10 cfu/g on dry basis.
