摘要:
The present invention provides a method of producing powder with a high tannin content, the method including pulverizing a tannin-containing plant such as bark of radiata pine (Pinus radiata) and classifying the pulverized material into fine particles having a desired particle size, for example, fine particles having a particle diameter of 100 to 1,000 mu m or less, and powder with a high tannin content produced by such a method. The thus obtained powder with a high tannin content exhibits excellent characteristics when used as an adhesive, a binder, etc. for wood materials.
