Determination of total cholesterol in meat and poultry by gas chromatography: single-laboratory validation.

The primary objective of this study was to determine the intralaboratory performance of a cholesterol determination method that combines direct saponification of a 1 g meat or poultry sample and GC quantification of liberated cholesterol without derivatization. Cholesterol was detected at 11.96 min using a GC-flame ionization detector (FID) system.
