Description

本発明は、前記課題を解決するため鋭意研究した結果、木部と比べてリグニン含量が低く、可溶性成分を多量に含む樹皮に注目し、破砕後の樹皮の大きさを過度に小さくしない、以下の各技術手段を選択し採用することによって、安価な設備を用いて、少ない投入エネルギーを用いた比較的穏和な条件下で原料樹皮の糖化を促進せしめることができることを可能ならしめた「樹皮原料から糖類を製造する方法」に関する下記の発明から選択される発明である。 As a result of earnest research to solve the above problems, the present invention has a low lignin content compared to the xylem, paying attention to the bark containing a large amount of soluble components, and does not excessively reduce the size of the bark after crushing, By selecting and adopting these technical means, it was possible to promote the saccharification of the raw bark under relatively mild conditions using low input energy using inexpensive equipment. It is an invention selected from the following inventions relating to “a method for producing saccharides from:
