In this package we will identify the most suitable type of bark material for the extraction of CT from Norway spruce (Picea abies) and Scots pine (Pinus sylvestris). Key characteristics for the selection of raw material are value and costs of the bark material and its composition and seasonal variation
Bark is produced during the whole year and is debarked in different ways. The key characteristics for the selection of raw material are value and costs of the bark material, and its composition and seasonal variation in composition. Early in the project, we will sample bark from Norway spruce and Scots pine at two occasions. The bark will be stored for chemical characterization, and used for extraction and characterization of condensed tannins for later use in testing for biological activity.
