Protein was extracted from mechanically pressed and hexane-extracted jojoba seed meal (Simmondsia chinensis), using four different procedures. These methods involved extracting protein with water, extracting protein with 0.15M NaCl, washing the meal with methanol/acetone (3:1) before extracting protein with water, or then rewashing this concentrate with methanol/1N HCl (98:2). The soluble protein content of the defatted meal was 20%. The above procedures recovered 18-65% of the total protein in the meal. Trypsin inhibitor activity and phytic acid concentrations were reduced to acceptable levels. Concentrations of simmondsin and polyphenolics were also significantly reduced.
