The Production of Japanese Agar and Gelatin in Edo Period

笔者选取伊豆地区和大阪北部地区作为琼脂和明胶的产地，考察了德川时代琼脂和明胶的生产结构。在伊豆，琼脂的购买被称为urauke的渔场垄断，原料和琼脂的价格因为Kishu封建氏族的介入而上涨。由于琼脂价格的显著上涨抑制了琼脂生产人同伴的经营，各封建氏族又加强了对琼脂的垄断制度，直接生产中心村庄之间的对立和村里农民之间的冲突就发生了。

I took up Izu area and northern Osaka area at the agar and gelatin production place, and this study examined production structure of agar and gelatin in Tokugawa Era. The purchase of the agar in Izu was monopolized by fishing ground usage called urauke, and raw materials and a price of the agar that it was rose because Kishu feudal clan intervened there. Because the remarkable rise of the agar price suppresses the management of the agar production person companion, and each feudal clan strengthened a monopoly system of the agar again, the opposition between the villages of the straight production center and the conflict between the farmers in the village occurred.
