Abstract
The present invention discloses a method for terminal inactivation of pathogenic microorganisms, comprising the following steps of: a. vacuum freeze-drying a bio-product packaged in a container, feeding in a gas and sealing to obtain the end product and, b. performing inactivation by dry-heating. The method provided by the present invention can effectively inactivate non-lipid enveloped viruses, with excellent inactivation effects and short inactivation time particularly to parvoviruses, and thus overcome the deficiencies of the conventional terminal dry-heating inactivation methods.
