Preparation of linseed emulsion:
Twenty five grams of linseed seeds (Linum usitatissimum ) were grounded and homogenated together with distillated water (300 ml) three times for 10 minutes. The mixture was filtered through gauze and then it was put in the centrifuge (x7000 rpm) for 20 min. The top liquid supernatant phase of the mixture was transferred to a new bottle. The bottle was then sonicated on ice for 6 minutes, and after 5 minutes of break it was sonicated again for more 6 minutes.
