Stability of emulsions formulated with high concentrations of sodium caseinate and trehalose
Stability of emulsions formulated with 10wt.% oil (concentrated fish oil, CFO, sunflower oil, SFO, or olive oil, OO), sodium caseinate concentrations varying from 0.5 to 5wt.%, giving oil-to-protein ratios of 20-2, and 0, 20, 30 or 40wt.% aqueous trehalose solution was studied by Turbiscan.
