The effects of droplet size and emulsifiers on oxidative stability polyunsaturated TAG in oil-in-water (o/w) emulsions with sizes 0.806 +/- 0.0690, 3.28 0.0660, or 10.7 0.106 microm (mean SD) were investigated. Hydroperoxide contents the emulsion a mean 0.831 significantly lower than those 12.8 for up to 120 h oxidation time. Residual oxygen headspace air vials containing an o/w compared microm. Hexanal developed from soybean oil smaller showed residual larger emulsions. Consequently, could be controlled by even though origins different. Spin-spin relaxation time protons acyl residues measured H NMR suggested that motional frequency some was shorter size. effect wedge associated hydrophobic proposed as possible mechanism explain differences between different sizes.
