Lipid Residue Analysis of Ceramics at Liangchengzhen

一、前言(一)综述食物消费的文化史是由社会身份和社会关系在权力和控制、合作与联系方面的重构组成。食物的消费是人类社会进程的一部分:食物不仅提供基本营养而且往往与人类共存。食物和它所代表的消费模式已成为一种分析过去社会的文化和社会变迁的范式~①。食物消费模式与文化、社会组织和社会身份密不可分~②。选择特定食物进行种植和把'食物资源'变成食物的预加工方式及烹调方式是'文化的核心过程'~③。

This study investigated the presence of lipid residues in various types of ceramic vessels from late prehistoric northern China in order to identify foodstuffs such as protein(meat,fish),grains(rice,millet),and other plants that explain different patterns of food consumption across space and time.Examination of intracultural consumption patterns via food residues provided an additional line of evidence for understanding of social and ritual activities in relation to social change at the site of Liangchengzhen in southeastern Shandong province(ca.2500-1900BC).Interpretations were made about the nature of consumption activities over time on the basis of vessels deposited in pits that were hypothesized as offering pits,versus storage and trash pits.In addition,consideration was given to spatial and chronological variation at the center with respect to the consumption of hypothesized preferred foods.In this research,GC-IR-MS is a useful approach to study residue analysis,it is also a new way to systematic study of food residues from the interior of Neolithic vessels from ancient China that will relate the results of the residue analysis to patterns of food consumption and social change.
