What Manichean said is probably the best way to quickly delete the plist file from all of the epubs.
You might also want to delete the iTunesArtWork file that may be present.
A word of warning though, through my extensive experience with manipulation of iTunesMetadata files and epubs I'd recommend zip.exe instead of 7zip (zip -d)
Over a couple of thousand books 7z complained in a high percentage of files of being unable to "open/write/update/etc" the epub while zip worked perfectly fine.
