A product is made from mushroom stumps, heretofore wasted. After a preliminary dry treatment to remove dirt, the stumps are washed, and then the wet product fiber is broken down to make a puree. The puree is separated, as by centrifuging or filtering, from the remaining dirt and impurities, and the separated puree is pasteurized. Then it may be concentrated and used as a liquid concentrate or may be dried and used as a powder. |
