In order to conserve and exhibit waterlogged archaeological wood, it is first necessary to remove excessive water from wood cells and reinforce the destructed cells. Recently in Europe, sugar, especially sucrose, which itself is a component part of wood, has been practically applied instead of PEG (Polyethylene Glycol) for the impregnation of archaeological wood for conservation. However, the use of sucrose is unsuited to the Japanese environment when Japan's hot and humid climate and the high risk of biological degradation are taken into consideration. Under such conditions a sucrose solution may ferment and the high humidity level may cause the sucrose to liquefy, which will in turn cause the risk of the treated wood being attacked by insects like ants. Having considered various sugar alcohols (industrially manufactured sugars) available that had properties such as low hygroscopicity, high water solu bility and microbiological stability, we decided to use the comparatively inexpensive lactitol and trehalose.The conservation method developed since 1994 has been using a sugar alcohol, namely lactitol, for the consery ation of waterlogged wood and lacquer ware. Using this method, impregnation of the waterlogged wood at room tern perature and raised temperature can be carried out. Now, over thirty separate organizations are using lactitol with success in Japan, Hungary, Mexico and Poland.I want to give a lecture about the latest result with the development of sugar alcohol method in this announcement.

为了保护和展示水口的考古木材，首先有必要从木细胞中去除过多的水并加强破坏的细胞。最近，在欧洲，糖，尤其是蔗糖本身就是木材的组成部分，实际上已被用于使用PEG（聚乙烯乙二醇），以浸入考古木材以保护。但是，当日本炎热潮湿的气候和生物降解的高风险被考虑时，蔗糖的使用不适合日本环境。在这种情况下，蔗糖溶液可能会发酵，高湿度水平可能会导致蔗糖液化，这反过来又会导致被处理的木材像蚂蚁一样遭到昆虫攻击的风险。在考虑了各种糖（工业生产的糖），具有低吸湿性，高水溶性和微生物学稳定性等特性后，我们决定使用相对便宜的乳糖醇和天甲糖。1994年以来开发的保护方法自1994年以来一直使用糖酒精，即乳脂醇，即乳糖糖果蛋白，是水上固有的lactecog aterpected Witterleceped witter of Witterllelllellllellllellllellllelllelllelllelllelllelllelllelllelllellelllececquesp and。schoples。使用这种方法，可以进行室内灌木丛和温度升高的水槽木材的浸没。现在，在日本，匈牙利，墨西哥和波兰成功的三十多个组织正在使用乳糖醇，并在此公告中对开发糖酒的发展进行了一次演讲。
