Research Abstract

In this work, we analyzed emulsion destabilization by bacteriostatic emulsifiers and applied the phenomenon to oil extraction and the control of flavor release. We revealed that oils can be extracted by the emulsifiers and the structural similarity between emulsifiers and oils did not necessarily relate to the oil extraction efficiency. Flavor release from model emulsion can be affected by oil droplet coalescence.
