A water-soluble fraction (WSF) was prepared by filtering 10 times diluted yolk (pH 5.0) stored at 4–6°C through Whatman No. 52 or No.1 filter paper for delipidation. However, solid-phase delipidation using an octadecyl column after filtration through a cellulose powder column was more practical for industrial application. After ultrafiltration (UF) of the WSF (pH 9.0,1.5M NaCl), results showed: Amicon 80–85% recovery, 74–99% purity; Harp 72–74% recovery, 81–84% purity; A/G 75% recovery, 89% purity; Koch 88% purity.
