In this paper, the results of chemical studies of lipid residues recovered from the ceramic matrices of containers from the archaeological site of Loma l´Antigo, a late settlement in the Valle del Cajón, Catamarca, Argentina, are presented. Residues extracted from 12 archaeological samples were analyzed by gas chromatography with flame ionization detection (GC-FID), and an ethnographic pot was studied by GC-FID and gas chromatography coupled to mass spectrometry (GC-MS) for comparative purposes. The identification of different fatty acid methyl esters (FAMEs) in nine of the archaeological samples and in the ethnographic pot is evidence of the use of the containers in different culinary activities that involved the circulation of substances of plant and animal origin. Various samples showed the presence of ruminant fat biomarkers compatible with camelids. The articulation of chemical studies with other sources of inquiry allowed us to verify the use of different types of containers for storage, preparation and service of foods and/or drinks.
