Abstract The abstract describing the content of the publication or report |
ω-(o-Alkylphenyl)alkanoic acids are known to form i in vitro from triunsaturated fatty acids following protracted heating. These compounds have been identified in absorbed lipid extracts obtained from archaeological pottery vessels, providing a potentially valuable new class of indicator for the processing of commodities, such as marine oils, which contain high abundances of polyunsaturated fatty acids. Experiments were conducted to assess whether ω-(o-alkylphenyl)alkanoic acids form when pure compounds and complex triacylglycerol mixtures are heated with a fired clay. The results demonstrate that ω-(o-alkylphenyl)alkanoic acids are only produced following heating of unsaturated fatty acids (tri-, di- and monounsaturated species) or complex unsaturated fatty acyl lipids at around 270°C. Heating saturated fatty acyl lipids does not yield ω-(o-alkylphenyl)alkanoic acids. Thus, when searching for evidence for the processing of marine derived animal fats in archaeological pottery vessels, it is essential that: ω-(o-alkylphenyl)alkanoic acids of carbon length C18and C20 should be present, ideally with C22 also detectable (if only in trace abundances), together with at least one of the three isoprenoid fatty acids (phytanic, pristanic or 4,8,12-tetramethyltridecanoic acid). | ||||
