从与考古陶器有关的脂类残留物中获得分子信息的可能性大大增加了获得有关古代器皿及其加工商品用途的新信息的可能性。由于考古陶片中含有动物脂肪的比例很高，人们开发了一种新的方法，包括对残留脂肪进行化合物特异性稳定同位素分析，以获取信息，这将使人们对史前人类的动物开发、饮食偏好和器皿使用有新的见解。新方法利用气相色谱-燃烧-同位素比质谱仪测定的主要饱和脂肪酸(C16：0和C18：0)的δ13C值来表征从考古陶器中发现的动物脂肪的来源。
The possibility of obtaining molecular information from lipid residues associated with archaeological pottery has dramatically increased the potential for deriving new information on the use of ancient vessels and the commodities processed therein. Motivated by the high proportion of the archaeological potsherds that have been shown to contain animal fats, a new approach invol- ving compound specific stable isotope analysis of remnant fats has been developed to retrieve infor- mation which will allow new insights into animal exploitation, dietary preferences and vessel use amongst prehistoric peoples. The new approach uses the δ13C values of the major saturated fatty acid (C16:0 and C18:0) determined by gas chromatography-combustion-isotope ratio mass spectrometry (GC–C–IRMS) to characterise the origins of animal fat recovered from archaeological pottery.
