Abstract

Phytosterols are used to lower the blood cholesterol. β-Sitosterol isone ofthe mostimportant phytosterolswith verypoorwater solubility and bioaccessibility. The maingoal of the current research was to investigate the effects of different emulsification variables (i.e. shear, time, pressure and cycle) on the physicochemical properties, release behaviour and encapsulation efficiency of β-sitosterol in water-in-oil-in water (W/O/W) emulsion. Initially, 19 β-sitosterol emulsions were prepared under different experimental conditions (shear 3000and6000rpm;time2.5 and 5min;pressure100,200and 300 bar; cycle 1–3). In this study, the β-sitosterol emulsion prepared at 6000 rpm, 5 min, 300 bar and 3 cycles had the smallest average droplet size (139 nm) among all prepared samples. The interaction between shear and time showed the most significant (P < 0.05) effect on the polydispersity index (PDI) and turbidity of the β-sitosterol emulsion. Increasing homogenization pressure and cycle led to improving emulsion stability and encapsulation efficiency. The β-sitosterol emulsion homogenised at 100 bar for 1 cycle had the highest encapsulation efficiency (81.7%) among all samples. The optimization study showed that the emulsification at 300 bar for 3 cycles resulted in the most desirable β-sitosterol emulsion.
