FFA released (µmol/mL) over a 60 min time period during duodenal digestion of oat emulsions (A) and sunflower emulsions enriched in phytosterols (B).Light microscopy images of oil bodies at time 0 (C1 and C2) and after 60 min of digestion (C3 and C4). Note the presence of flocculation in C2 and remaining lipids inC4, the lipids being stained in red with Nile red. Ocrude, crude oil from oats; OPL4, oat oil with ∼4% polar lipids; OPL15, oat oil with ∼15% polar lipids; PS:phytosterols; SOs, Florisil®-treated sunflower oil.
