Particle size distribution (A and B) and ζ-potential (C) of micelles generated from oat emulsions (A) and sunflower oil emulsions (SOs) enriched with 0–2.0%phytosterols (B). Different letters indicate significant differences as determined by one-way ANOVA and Tukey’s post hoc test (C1 and C2). Ocrude, crude oil fromoats; OPL4, oat oil with ∼4% polar lipids; OPL15, oat oil with ∼15% polar lipids; PS: phytosterols; SOs, Florisil®-treated sunflower oil.
