The total lipid content of a food is commonly determined
by organic solvent extraction methods. The
accuracy of these methods greatly depends o~ ~e solubility
of the lipids in the solvent used. :ne 1i~ld content
of a food determined by extraction With one
solvent may be quite different from the content determined
with another solvent of different polarity. In
addition to solvent extraction methods, there are nonsolvent
wet extraction methods and several instrumental
methods that utilize the physical and chemical
properties of lipids in foods for fat content determination.
