INTRODUCTION
Crude Fat is generally defined as sample constituents soluble in
appropriate organic solvents, such as diethyl ether, petroleum
ether or chloroform. The main constituents in Crude Fat are
triglycerols and free fatty acids. In certain Sample types, however,
some of the fat, or lipids, are bound as lipoproteins,
liposaccharides or metal salts. Solvents are not capable of
breaking such bonds, therefore hydrolysis is used to transform
these lipids into extractable forms.
The 1047 Hydrolyzing Unit in combination with Soxtec System
HT enables total fat extractions to be performed in a simple way
in a variety of Sample types.
