ABSTRACT:

Fractionation by supercritical carbon dioxide (SC-CO2) might be a way to purify used frying oils, since a selective separation of the oil components based on their polarity and M.W. can be attained. In this work, we studied the purification of peanut oil used for frying by SC-CO2 continuous fractionation in a packed column. The influence of pressure (15-35 MPa) and temperature (25-55°C) on the yield and on the composition of products was determined. The composition of the to...
