Abstract (en)
[origin: WO2016096781A1] The invention relates to a process for obtaining a conifer bark-base composition enriched with dihydroquercetin or with tannins, comprising the following steps: a) grinding dried shavings of bark from a conifer so as to obtain a ground conifer bark particle material, and b) selecting, from the ground particle material obtained in step a), the fraction of particles:- of smallest size representing at most 40% by weight, relative to the total weight of the ground particle material obtained in step a), this fraction being enriched with tannins; or - of largest size representing at most 50% by weight, relative to the total weight of the ground particle material obtained in step a), this fraction being enriched with dihydroquercetin.
