Oleogel-Based Water-In-Oil Pickering Emulsions Stabilized Solely by Birch Outer Bark Extract Particles

Short Introductive summary

This study introduces a novel approach for obtaining stable water-in-oil Pickering emulsions stabilized by birch outer bark extract microparticles, using pre-formed oleogel as a feedstock, aiming to offer a natural and sustainable alternative to conventional synthetic stabilizers. The key innovation lies in replacing traditional multi-step, solvent-intensive and energy-consuming methods for obtaining birch outer bark extract particles with a simplified, low-pressure, ethanol-based process, that directly yields functional oleogels containing uniformly dispersed microparticles.
