The result of the colloidal stability of the milk types
under refrigeration is presented in Table 2. The apparent
colloidal stability of all milk types decreased when stored
under refrigerated condition for 72 h, however, with the
exception of soy-corn milk the decrease was not statistically significant (P>0.05) from the value measured at 0 h.
this significant decrease in colloidal stability of soy-corn
milk within 72 h under refrigerated condition, was also observed by Omueti and Ajomole (2005) where the colloidal
separation of the product was reported.
The result of the pH of the samples under refrigeration
for 72 h is presented in Figure 2. There was no significant
difference (P>0.05) in the pH of the milk type at preparation, while the value ranged between 6.8 and 6.5 which is
withinthestandard(ShojaeiandYodollahi2008).Thespiced
