Abstract: | Distributions of erythro and threo dihydroxy acids, extracted from ‘bound’ forms of organic residues preserved in archaeological pottery cooking vessels are shown to be the direct products from Z-monounsaturated alkenoic acids present in the original commodities, and are useful biomarkers for detecting marine animal product processing/consumption by ancient people. |
