Our laboratory offers an applicative research service and an analytical quality control service on chemical plants for the production of vegetable extracts, in particular natural tannins and polyphenols. These natural substances are extracted from parts of plants like trunks, barks, leaves, pods, gallnuts. Our research starts from the laboratory level, up to the scale-up of the processes that are transferred to the industrial production plants. Our work is also to guarantee products in compliance with current international regulations and without quality problems.
