Abstract
An albumin preparation may be produced efficiently on a commercial basis that has reduced possibility of contamination of infectious viruses and has high safety and stability. The process according to the present invention comprises a step of filtration of a serum albumin-containing solution with a virus-removing membrane preferably with a pore size of 10 to 20 nm. In particular, said filtration is performed before heat treatment for inactivation of viruses. In a more preferable embodiment, said serum albumin-containing solution is treated with an anion exchanger and/or a prefilter before a step of said filtration.
