Abstract
The use of microwave irradiation as a pretreatment before aqueous enzymatic oil extraction from oil palm kernel was found to be useful. The microwave irradiation for 10 min -assisted extraction was found to be a simpler and more effective alternative to the solvent extraction methods for the productions of palm kernel oil. Further enhancement was achieved when the microwave irradiated slurries were treated with a commercial enzyme preparation of proteases, followed by three phase partitioning. This resulted in 93% (w/w) oil yields form the palm kernel. The efficiency of the present technique is comparable to solvent extraction with an added advantage of being less time consuming and using t-butanol which is a safer solvent as compared to n-hexane used in conventional oil extraction process. The technique also tries to reduce the amount of enzyme used and hence reduces the overall cost.
