Fine emulsions formulated with non heated whey proteins
showed thinner consistency (liquid like, with a milky appearance). However, fine emulsions formulated with
denatured proteins (particularly at 90ºC) showed gelation after high pressure homogenization, especially after
the second cycle of homogenization.
Such decrease in droplet size could be associated with the
exposition of hydrophobic groups of whey proteins that easily interact with oil phase, stabilizing the O/W
interface and avoiding or delaying the cremeation process.
