ReviewThree phase partitioning for extraction of oil: A review

- Extraction of oil using three phase partitioning from different sources is reviewed.
- Effects of parameters like salt, solvent, pH, temperature, pre-treatments are discussed.
- Mechanism and advantages of TPP for oil extraction are expressed along with yields from different source.
- Performance of TPP was compared with standard methods.

Recently, numerous extraction techniques for oil and lipid have been studied and employed. In spite of that; hexane extraction method happens to be widely used on the commercial platform. Application of three phase partitioning (TPP) was emerged out as a greener alternative to the hexane extraction that simultaneously yields separation of other valuable bio molecules like proteins. Researchers have practiced TPP along with pre-treatments like incubation with enzymes, ultrasound and high pressure that can amplify the oil extraction. The aim of this review is to sum up the oil extraction studies executed using TPP; that eventually open up the new research area for developing eco-friendly and efficient method of oil extraction. In addition to this; contribution of various important parameters to extraction efficiency of TPP are also reviewed in this article for better understanding of the process.
