ABSTRACT:
An improved process for delignifying and bleaching nonwoody, lignocellulosic material into products digestible by ruminants and ingestible by humans. The process comprises treating the substrate in an alkaline solution for a period of time and adding magnesium ions prior to adding peroxide or, alternatively, adding the magnesium to the peroxide prior to adding the peroxide to the alkaline slurry.
