Supercritical CO2 extraction for total fat analysis of food products

Supercritical CO2 extraction (SFE) is a promising alternative to solvent ex traction for the measurement of total fat in food products. Total fat was e xtracted by SFE from samples of food products of different compositions and fat contents. Results using SFE were statistically compared with those usi ng standard methods. This feasibility study showed very promising results. A suitable method was developed for analysis of full milk powder and dietet ic milk powder and recoveries were 97.4 and 98.4% respectively. The content of the major fatty acids of fat extracted with SFE was similar to that of Rose-Gottlieb solvent extraction.
