Selective removal of green pigments and associated proteins from clover-grass protein concentrates: molecular insights into a non-destructive, two-stage membrane-based biorefinery concept for high-quality food protein production

A two-stage membrane-based green biorefinery removes pigments (Chl + Cart) via selective retention of large complexes with specific proteins (CBPs and PI/II) thereby producing a RuBisCO- and antioxidant-rich concentrate suitable for food application.
