Abstract [en]

Thisis an experimental study of lipid residues within the field of laboratoryarcheology. Pottery was made in a time like manner and used to cook grain and Icelandmoss and exposed to an organized biodegradation experiment inside an incubatorfor later analyzes with the GC-MS-method. Tests were also taken from pottery,grain and Iceland moss that had not been exposed for a biodegrading attempt.The grain is a domesticated cereal and the Icelandic moss fungi-alga mix. Thetest results showed mostly saturated fatty acids, sterols and monoacylglycerolsof saturated fatty acids. Within the laboratory archeology, ergosterol has beensuggested as a possible biomarker for yeast and alcohol fermentation. TheIceland moss contains ergosterol and is therefore relevant for the study whenit can be compared to archeological pottery that contains ergosterol. Theresults didn’t show any traces of ergostrol with the biodegraded pottery, butlow traces of cholesterol witch probably is contaminations from the handlingwith the pottery.
