In this study, we investigated the effect of high pressure homogenizer on the physico-chemical properties of capsicum oleoresin loaded nanoemulsion (NE) or nanocapsules (NCs) based on the emulsion-diffusion method. According to the application stage of high pressure process at principle emulsion-diffusion method, NCs was prepared by conventional-emulsion-diffusion method (CED), modified-emulsion-microfluidization-diffusion method (MEMD) and modified-emulsion-diffusion-microfluidization method (MEDM). The nanocapsules of MEMD showed homogeneous and the smallest particle size as compared with CED. In addition, MEMD presented the surface tension at the value 36.5 mN/m. The encapsulated capsicum oleoresin was generated the bright color and suppressed the dark red color. Furthermore, MEMD gave the high encapsulation efficiency of capsicum oleoresin around 95% and showed the slow release rate. On the other hand, MEDM presented the non-homogeneous and agglomerate of the particle, low percentage of encapsulation efficiency and the high initial release rate when compared with CED and MEMD methods. According these results, it was supposed that the microfluidization was interesting technique to ameliorate the physical properties and efficiency of NCs. However, it was depending on the appropriate combination of microfluidization based on the emulsion-diffusion method.
