Lipids, pots and food processing at ho;evarica, ljubljansko barje, slovenia

Abstract

The paper presents the results of lipid analyses of pottery samples from Ho≠evarica (Ljubljansko barje, Slovenia). Total lipid extracts were subjected to high temperature gas chromatography (HT-GC), gas chromatography- mass spectrometry (GC-MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). The results show that some vessels were used for preparing ruminant meat and vegetable, but also the remains of aquatic food were identified. The processing of non-ruminant meat was detected in a few samples. A high number of pottery samples yielded the presence of beeswax lipids. The charred residual on pottery was AMS 14C dated. IZVLE∞EK - V ≠lanku predstavljamo rezultate analiz lipidov ohranjenih v kerami≠nem zbiru s Ho≠evarice. Lipide, ekstrahirane iz ostankov kerami≠nih posod, smo analizirali s pomo≠jo plinske kromatografije pri visokih temperaturah (HT-GC), plinske kromatografije sklopljene z masno spektrometrijo (GC-MS) in plinske kromatografije sklopljene z masnim pektrometrom za analizo stabilnih izotopov lahkih elementov preko se∫igne enote (GC-C-IRMS). Rezultati ka∫ejo, da so v posodah pripravljali hrano iz mesa pre∫vekovalcev in zelenjave; redko iz mesa nepre∫vekovalcev. V drugih so pripravljali hrano iz sladkovodnih rib. V Πtevilnih posodah je bil odkrit ≠ebelji vosek. Karbonizirani ostanki na posodah so bili AMS 14C datirani.
