PURPOSE:To obtain a plasma protein containing little ill-odor and coloring substances using an industrially suitable process in high recovery by contacting a plasma with an adsorbent under specific condition. CONSTITUTION:Blood plasma having improved quality can be prepared by contacting plasma with an adsorbent (e.g. activated carbon, silica get, alginic acid or polyacrylic acid) at a protein concentration of 2-5%, a liquid temperature of 20-30 deg.C and pH 3-5. The obtained improved plasma solution is returned to neutral pH condition or concentrated as necessary. |
