after the CaCl2 was added to the
emulsions and they had been stored at 30C. In the
absence of calcium chloride there was a significant
increase in mean particle size around the isoelectric
point (4 < pH < 6) of the whey proteins, which suggested that appreciable droplet aggregation occurred.
The addition of CaCl2 to the emulsions significantly
altered the extent of droplet aggregation.
