Resumen
The paper discusses the application of a lignocellulosic fractionation process to recover both antioxidant phenolic compounds and cellulose from wheat straw, where the first hydrolysis step is carried out as an auto-hydrolysis novel process instead of a conventional mild acid hydrolysis. The two different processes were compared and auto-hydrolysis resulted more effective in separating cell-wall bound phenolic compounds, antioxidants and cellulose from wheat straw. Therefore, it could be recommended for replacing the aggressive acid hydrolysis step in the isolation of natural antioxidants and fibers from wheat straw and other similar biomasses.
