Abstract: In order to overcome limitations of peppermint oil such as high volatility and poor water solubility, peppermint oil nanoemulsions were prepared by high pressure homogenization method using soybean protein-phosphatidylcholine complex as the emulsifier. Based on average particle size, polydispersity index, zeta potential, turbidity, emulsification yield and emulsion stability index, the optimum process parameters were determined as follows: soy protein isolate (SPI) concentration 2.5% (m/m), peppermint oil 5% (m/m), and homogenization pressure 80 MPa. Peppermint oil nanoemulsions with a small average diameter and uniform size distribution were obtained under the optimized conditions as examined by dynamic light scattering and transmission electron microscopy. Analysis by gas chromatography-mass spectrometry (GC-MS) showed that the nanoemulsions could effectively preserve the functional components of peppermint oil; the rheological results showed that the peppermint oil nano-emulsion had good kinetic stability.
