Oleogelation of emulsified oil delays in vitro intestinal lipid digestion

Oleogelation is shown to delay the in vitro digestion of soybean oil (SBO) dispersed within an oil-in-water (O/W) emulsion. Rice bran wax (RBX) was used as an oleogelator at concentrations of 0, 0.25, 0.5, 1 and 4 wt% of the emulsions. All emulsions, which contained 1 wt% whey protein and 20 wt% oil and were prepared via hot homogenization, were kinetically stable against phase separation during the experimental timeframe (4 weeks), except at 4...
