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.

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.
