“…However, it has been noted that, although present in significant concentrations around the rim, these lipids exhibit a higher degree of degradation, probably due to their contact with air that promotes oxidation (Regert et al, 1999). Furthermore, it has been shown that concentration gradients exist between the inner and the outer surface of the sherds (Stern et al, 2000).…”

Mass spectrometry (MS) is an essential tool in the field of biomolecular archeology to characterize amorphous organic residues preserved in ancient ceramic vessels. Animal fats of various nature and origin, namely subcutaneous fats of cattle, sheep, goats, pigs, horses, and also of dairy products, are those most commonly identified in organic residues in archeological pottery. Fats and oils of marine origin have also been revealed. Since the first applications of MS coupled with gas chromatography (GC) in archeology at the end of 1980s, several developments have occurred, including isotopic determinations by GC coupled to isotope ratio MS and identification of triacylglycerols (TAGs) structure by soft ionization techniques (ESI and APCI). The combination of these methods provides invaluable insights into the strategies of exploitation of animal products in prehistory. In this review, I focus on the analytical strategies based upon MS that allow elucidation of the structure of biomolecular constituents and determination of their isotopic values to identify the nature of animal fat components preserved in highly complex and degraded archeological matrices.

“…One study found low, but quantifiable, abundances of fatty acids in previously Soxhlet extracted pottery (62), suggesting that background levels of fatty acids are between 3 and 13 µg/g, and Evershed (4) suggests that levels of residues below 5 µg/g should be considered as background.…”

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

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 specific and detailed interpretations of materials preserved in the archaeological record. However there are still areas where we know very little, like the mechanisms at work during the formation and preservation of residues, and areas where each advance produces more questions rather than answers, as in the identification of degraded fats. This chapter will discuss some of the significant achievements in the field over the past decade and the ongoing challenges for research in this area.1341280_File000001_20903114.docPrinted 7/19/2013 2

“…Based on the ability to resolve the individual components of the often complex mixture of lipids found in potsherds, these techniques have been successively used in the identification of natural products such as resins, tars, pitch and beeswax (Aveling & Heron 1999;Hayek et al 1990;Heron et al 1994;Regert et al 1998;. Also, to identify the components of foodstuff processed or stored in ancient vessels (Stern et al 2000;Evershed et al 1991;.…”

Recent development in chemical analyses of organic remains in archaeological ceramics gives new possibilities to the study of pottery use. They could be of crucial importance in assessing vessel’s use, especially when combined with contextual, technomorphological and use-alteration analysis data. Using the example of the late Neolithic pottery from Makriyalos, Northern Greece, we discuss some of the problems in determining the use of the vessels from archaeological context, and show the benefits of integrating chemical analysis of organic remains in approaching this issue.
