The protein solubility, emulsifying, foaming and gelation properties,
and viscosity of solutions of chhana whey protein powders, produced by
ultrafiltration and reverse osmosis followed by drying, were studied
over the pH range 2.5-9.0. Protein solubility varied from 57-100% and
was greatest at low pH values. Chhana whey protein powders had similar
emulsifying properties to commercial cheese whey protein powders of s
imilar protein content, although the capacity to form gels when heated
to 80 degrees C was much lower, particularly at alkaline pH. The visc
osity of solutions of the chhana whey powders was sensitive to pH, but
was particularly high in the acidic range. These studies demonstrate
considerable potential for the utilization of chhana whey products in
the food industry.
