The rheological behavior of cottage cheese cream dressings
prepared with different stabilizing systems were shown to be
dependent on formulation, pH, and temperature. All samples were
shear-thinning, and the degree of shear thinning increased with
increased number and concentration of hydrocolloids used in the
formulation. Viscosity generally increased with decreased temperature
and pH, although the relationship between viscosity and
pH was complex. Cottage cheese cream dressing stability increased
with increased number and concentration of hydrocolloids used in
the formulation. Stability was impacted by pH, with the specific
about 5.0, the best stabilization system investigated in this study
would be 0.2% xanthan gum, 0.1% guar gum, and 0.1% locust bean
gum. However, this selection is assuming that the creamed cottage
cheese is kept at constant temperature and pH during a two-week
shelf life. For proper stabilization, the expected ranges of pH and
effects dependent on the formulation used. Cream dressings prepared
with either 0.2% xanthan gum or 0.2% xanthan gum, 0.1%
guar gum, and 0.1% locust bean gum showed the greatest stability,
indicating that they were the most resistant to whey separation of
all samples evaluated. The results of this study highlight the
importance of understanding the interactions between pH, temperature,
and stabilizing system when formulating cottage cheese
dressing. Given that the pH of most commercial cottage cheeses is
