(a,b) Variations in hydrodynamic diameter (nm) with time (days) of olive oil-PF 127-water nanoemulsions stored at room temperature (black open square) and stored at 4–8 °C in a refrigerator (red open squares). (a) for a week and (b) for a month. (c,d) Variations in the hydrodynamic diameter (nm) with time (days) of gelatin encapsulated olive oil-PF 127-water nanoemulsions (G-NE) stored at 4–8 °C in refrigerator, (c) for a week and (d) for a month.
