Optimization of process parameters in preparation of tocotrienol-rich red palm oil-based nanoemulsion stabilized by Tween80-Span 80 using response surface methodology
Fig 5
Effect of surfactant concentration, glycerol concentration in aqueous phase and homogenization pressure on polydispersity index of red palm oil (RPO) nanoemulsion.
Response surface plot showing the effect of (A) 10 wt% of surfactant concentration and 20 wt% of glycerol concentration, (B) 10 wt% of surfactant concentration and 600 bar homogenization pressure, (C) 20 wt% of glycerol concentration and 600 bar homogenization pressure, on polydispersity index (PDI) of red palm oil (RPO) nanoemulsion, missing independent variable in each figure was kept at the centre point.
