Offre de thèse : Protein survival in charred “foodcrusts”: insights into Mesolithic container technology (York/Copenhagen)

Logo University of CopenhagenLogo University of York

Thick charred and semi-charred surface deposits can often be found adhering to the inside of ceramic vessels as past remnants of food processing. Organic analysis of many hundreds of such ‘foodcrust’ samples has shown excellent preservation of lipids and unusually high amounts of nitrogenous compounds, making these ideal targets for proteomic analysis. This approach has the benefit of generating much greater taxonomic resolution than lipid analysis, however the degree of protein survival, and potential biases in dietary interpretations have not been systematically explored.

PhD starting October 2021 and recruiting now.
