Changes in apparent viscosity of the beverages were compared (Fig. 4). In the initial state at day 0, the samples prepared at homogenization pressure of 29.4 MPa were more viscous than the other two groups (0 and 19.6 MPa). Rubico, Resurreccion, Frank, and Beuchat (1987) also observed increased viscosity with increased homogenization pressure for a peanut beverage prepared from unroasted peanuts. This result could be influenced by the increase of solubility and intermolecular interaction among ingredients through the minimization of particle size with high homogenization pressure. Apparent viscosity of the samples prepared at 19.6 MPa was nearly constant, regardless of the three adjusted pHs (5.5, 6.5, and 7.5), with the exception of the sample stored at 40 °C.
