Abstract
A method of producing powder with a high tannin content includes pulverizing a tannin-containing plant such as bark of radiata pine () 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 μm or less. A powder with a high tannin content is 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.
