The objective of the present study was to investigate the effect of high‐pressure homogenization conditions, namely pressure (20–80 MPa) and number of cycles (1–3 cycles), on the properties of palm‐based functional lipids. Nanodispersions prepared with palm‐based functional lipid and Tween 20 were characterized by monitoring their physicochemical and morphological properties. The results showed that high‐pressure homogenizer was an efficient emulsification technique producing small emulsion droplets with narrow size distribution. In general, the results showed that different homogenization conditions had significant ( p < 0.05) effect on the size distribution of prepared nanodispersions. Average particles ranging from 95 to 130 nm and 140 to 210 nm were obtained for the nanoemulsions containing palm‐based tocopherol–tocotrienol and carotenoid, respectively. However, this study indicated that increasing the energy input beyond moderate pressures (20–80 MPa) and cycles (1–3) led to “over‐processing” of droplets. The nanodispersions proved to be physically stable and showed good stability during 12 weeks of storage.
