Abstract

ABSTRACT The adoption of pottery in the Upper Great Lakes region occurs quite late compared to the greater Eastern Woodlands. Recent organic residue analyses suggest that the earliest pottery in the Upper Great Lakes region was likely used to process acorns. Through experimental means using temperature as a proxy, this paper evaluates the efficacy of leaching tannins from acorns by comparing two regionally available cooking technologies: stone boiling versus simmering in a ceramic vessel. Our results indicate that tannins can be more effectively leached at simmering temperatures like those provided by ceramic vessels. At boiling temperatures, tannins are irreversibly bound to the acorn starches, rendering the nutmeat inedible in further processing. While there are a number of reasons to adopt and use pottery, it appears that processing acorns may be another important addition to this growing list.

五大湖上游地区橡子加工与陶器利用:沸石与陶瓷工艺的实验比较

与大东部林地相比，上五大湖地区采用陶器的时间要晚得多。最近的有机残留物分析表明，上五大湖地区最早的陶器可能是用来加工橡子的。通过实验手段，以温度为代表，通过比较两种地区可用的烹饪技术:石煮和在陶瓷容器中煨，评估从橡子中浸出单宁的功效。我们的研究结果表明，单宁可以更有效地浸出在沸腾的温度，如陶瓷容器提供。在沸腾的温度下，单宁与橡子淀粉不可逆地结合在一起，使坚果在进一步加工中不可食用。虽然采用和使用陶器的原因有很多，但加工橡子似乎是另一个重要的原因。

期刊介绍： Ethnoarchaeology, a cross-cultural peer-reviewed journal, focuses on the present position, impact of, and future prospects of ethnoarchaeological and experimental studies approaches to anthropological research. The primary goal of this journal is to provide practitioners with an intellectual platform to showcase and appraise current research and theoretical and methodological directions for the 21st century. Although there has been an exponential increase in ethnoarchaeological and experimental research in the past thirty years, there is little that unifies or defines our subdiscipline. Ethnoarchaeology addresses this need, exploring what distinguishes ethnoarchaeological and experimental approaches, what methods connect practitioners, and what unique suite of research attributes we contribute to the better understanding of the human condition. In addition to research articles, the journal publishes book and other media reviews, periodic theme issues, and position statements by noted scholars.
