  • Publication number: 20190151425
    Abstract: Processes are described for producing solid or semi-solid compositions, in particular solid oral compositions for pharmaceutical use, comprising treating an enzyme or enzyme-mixture with lipase-activity and a surfactant-component at defined process parameters. Said processes are suited for diminishing undesired biological contamination, e.g. viral contamination, of the said enzyme or enzyme-mixture while maintaining its desired biological activities, e.g. enzymatic activities. The process is suitable for industrial use. Also described are solid or semi-solid compositions comprising an enzyme or enzyme-mixture having lipase activity, a surfactant-component and a polymeric additive, optionally comprising further auxiliaries. Said compositions can preferably be obtained by the processes as described herein. Further described are pharmaceutical compositions comprising the solid or semi-solid compositions as described herein.
