Pots and lipids: molecular and isotope evidence of food processing at Maharski prekop

The pottery assemblage from the Maharski prekop site was analysed to obtain insights into vessel use and husbandry practices. Total lipid extracts of pottery samples were subjected to gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), gas chromatography-combustion- isotope ratio mass spectrometry (GC-C-IRMS) and soft ionisation electrospray mass spectrometric techniques ESI Q-TOF MS and ESI Q-TOF MS/MS. The charred organic deposits on vessels were AMS 14C dated. The results show that some vessels were used for cooking ruminant meat, while in other traces of mixed non-ruminant and ruminant meat or plants and animal meat cooking were identified. Some vessels were used for milk processing. Analizirali smo ostanke keramičnih posod z Maharskega prekopa, da bi dobili dodatne informacije o uporabi keramičnih posod in zgodnji živinoreji. Lipide, ekstrahirane iz ostankov keramičnih posod, smo analizirali s pomočjo plinske kromatografije (GC), plinske kromatografije sklopljene z masno spektrometrijo (GC-MS), plinske kromatografije sklopljene z masnim spektrometrom za analizo stabilnih izotopov lahkih elementov preko sežigne enote (GC-C-IRMS) in masnim spektrometrom z analizatorjem na čas preleta ionov (TOF) z elektrosprej ionizacijo (ESI Q-TOF MS in ESI Q-TOF MS/MS). Karbonizirani ostanki na posodahso AMS radiokarbonsko datirani. Rezultati kaŽejo, da so nekatere posode uporabljali za kuhanje mesa prežvekovalcev. V drugih posodah zasledimo ostanke kuhanja mešanega mesa prežvekovalcev in neprežvekovalcev ali ostanke kuhanja mešanice rastlinske in živalske hrane. Nekatere posode pa so bile uporabljene za predelavo mleka.
