Organic Residues in Archaeology: The Highs and Lows of Recent Research

Abstract: The analysis of organic residues from archaeological materials has become increasingly important to our understanding of ancient diet, trade and technology. Residues from diverse contexts have been retrieved and analysed from the remains of food, medicine and cosmetics to hafting material on stone arrowheads, pitch and tar from shipwrecks, and ancient manure from soils. Research has brought many advances in our understanding of archaeological, organic residues over the past two decades. Some have enabled very … Show more

“…Rather than the reliability of the measurement, the central concern in the use of gas chromatography is the contamination of archaeological samples by similar chemical compounds derived from modern sources. For instance, compounds derived from hand oils, plastic, sunscreen and other lotions can be similar to archaeologically significant compounds (Steele, 2013). Given these potential significant biases, that are always present, especially during the excavation and postexcavation stages of sample recovery, contaminants and sample contamination have received surprisingly little attention in publications on archaeological residue analysis.…”

“…While squalene is a common lipid in many organisms and highly commercialized today for its antioxidant properties (Steele, 2013), it has also been widely reported to occur in germinated grain (Briggs, 1978, 116) and yeast (Blagovic et al, 2001), which is the most important ingredient in brewing beer. Indeed, yeast is a single-cell organism, one of the simplest forms of plant life, which is responsible for the fermentation process in beer.…”

“…As revealed above, in all previous studies, a single transition for each target organic acid was monitored one by one in MRM mode. 22 Our data show that MRM mode is more favourable than previous ones using the following transitions: three for TA (i.e. 149/103, 149/131 and 149/87) and two for SA (i.e.…”

“…Finalmente, el análisis de los sedimentos permite descartar a priori la contaminación de los artefactos arqueológicos por migración de sustancias, dado que los ácidos grasos identificados -C16:0, C18:0 y C18:1-se presentan en forma de trazas. Su presencia podría relacionarse con la descomposición de materia orgánica que, a partir de procesos pedogénicos, pasa a formar parte de la matriz sedimentaria (Steele 2013).…”
