Description
Ultrasonic emulsification uses high‑frequency cavitation to produce nano‑sized droplets in sauces.
Technical
The ultrasonic field generates micro‑bubbles that collapse violently, creating intense shear forces that break up oil droplets into the sub‑micron range. Surfactant molecules rapidly adsorb to the newly exposed interfaces, forming a stabilizing film that reduces interfacial tension and prevents coalescence. Temperature control is critical because heat generated by cavitation can denature heat‑sensitive ingredients and alter emulsion stability.
