What You Need to Know
The process involves rapid dehydration of phosphatidylcholine/cholesterol bilayers, which collapses the vesicle while trapping essential oils inside. Thermal energy is carefully controlled to avoid lipid oxidation and maintain unsaturated fatty acids, ensuring high encapsulation efficiency (70–90 %). Upon rehydration or pH change, the vesicles re‑form, releasing the flavor in a targeted manner.
The Science
Primary Reaction
