Gas Chromatographytrition labeling requirements for total fat and saturated fat. This laboratory exercise involves solvent fat extraction, followed by saponification and then methylation with boron trifluoride to form fatty acid methyl esters. The sample is then subjected to GC analysis, with quantification and ident
