Abstract

Defatted safflower [Carthamus tinctorius L.] seed meal was deliganded by repeated extraction with 750 ml-1 ethanol. This reduced the colour/ligand concn. to <1% of the original concn. As a result, the protein concn. increased from 585 to 686 g kg-1 after deliganding. Proteins from the deliganded flour comprised 4 protein fractions, as observed from the gel filtration profile and sedimentation velocity pattern. However, the polyacrylamide gel electrophoretic pattern indicated 6 protein bands. Functional properties such as bulk density and water absorption capacity increased after deliganding. Fat absorption, emulsification and foaming properties showed a decreasing trend as a result of deliganding.
