The emulsifying activity of both powders is shown in Fig. 5. It is low at slightly
acid pH and increases until it stabilizes at slightly basic pH. Nevertheless, the
activity to the protein obtained by freeze drying is higher.
The wettability of the powder obtained by spray drying was 13 min and that
processed by freeze drying, due to its higher porosity it was 6 min and 2.5 s. Nevertheless,
in both cases the wettability is low and the solution was not complete.
