This dry process involves a grinding and then a sifting step. Some of the fractions obtained are highly enriched in components of interest: one fraction contains 80% of the initial taxifolin content (dihydroquercetin), and another 50% of the tannins.

  • This mainly mechanical and dry process offers an alternative to existing wet processes that use pollutant and expensive solvents.
  • Proved to work on Douglas pine tree barks and can be used with other conifers.

Numerous therapeutic properties: anti-inflammatory, anti-allergenic, hepatoprotective, antioxidant and anti-proliferative.

Applications: cosmetics, pharmaceuticals, food industry
Patent: WO2015EP79684 (2014/12/15)
