Abstract

BACKGROUND Phytosterols, in particular a mixture of pure γ‐oryzanol and β‐sitosterol, develop a tubular system that is able to structure oil. In this study, different concentrations of a combination of γ‐oryzanol and a commercial phytosterol mixture, Vitaesterol®, were used for the development of edible oil oleogels. RESULTS Small Angle X‐ray Scattering (SAXS) and X‐Ray Diffraction (XRD) were used to characterize at nano and molecular scale the aforementioned oleogels and confirm the formation of sterols‐based hollow tubule structures. Increased hardness was observed with the increase of gelat ...
