| Abstract: |
| Rubber seed oil was separately extracted from rubber seed by pressing method, leaching method, ultrasound-assisted solvent method and aqueous enzymatic method. The oil extraction rates, physicochemical properties and fatty acid compositions of rubber seed oils obtained by different processes were compared. The results showed that the ultrasound-assisted solvent method had the highest oil extraction rate, while that of aqueous enzymatic method was the lowest. The content of water and volatile matter in the oil obtained by aqueous enzymatic method was higher. The leached rubber seed oil had the highest acid value, while that of pressed rubber seed oil was the lowest. The peroxide value of pressed rubber seed oil was the highest ,while that of aqueous enzymatic extracted oil was the lowest. The fatty acid compositions of the four rubber seed oils were basically the same. |
