Recovery Of Residual Oils After Mechanical Press Using Supercritical Fluid Extraction
•Full Article: Recovery Of Residual Oils After Mechanical Press Using Supercritical Fluid Extraction
Supercritical fluid extraction is an extraction process using a supercritical fluid as a solvent.
When a fluid is taken above a particular temperature and pressure (critical point of the respective fluid), it exists in a condition called the supercritical fluid state. The physico-chemical properties of a fluid in the supercritical state are in between those of a typical gas and liquid.
Supercritical fluid technology has re-emerged in the last decade mainly due to new trends in the food industry as well as a dramatic rise in the research and development (R&D) activities focused on innovative approaches.
The movement from R&D to the commercial sector and its subsequent successful implementation is the key to the future of this technology. In the past, supercritical fluid technology was used only in niche applications because of its high capital cost and lack of professionals with knowledge of supercritical fluid technology. With the introduction in the past few years of lowcost equipment to complement the inherent low operating cost of supercritical plants, new processes have been developed and successfully implemented in the edible oil industry. Examples include de-oiling of crude lecithin as an alternative to using acetone as a solvent, oil extraction from spent bleaching earth, which offers an environmentally friendly solution for disposal of spent bleaching earth; and recovery of phytosterol and vitamin E from deodorized distillates.
