Emulsions useful in beverages
View Patent ↗It has now been found that emulsions having a discrete phase volume fraction of 60% to 67% with excellent stability may be prepared using at least one low molecular weight surfactant. Such emulsions have high oil loading and a small mean particle size of less than 0.2 microns. Further, such emulsions may be used in beverages without weighting agents.
