Apparently, Chrome does not have its own mime-handling database, but uses that of your desktop environment.

In my XFCE4-based environment, for example, the settings are controlled through the xfce4-settings app (xfce4-mime-settings specifically).

On a Windows desktop, you'd go through the "Default Programs" part of the "Control Panel", as described in (painful) detail here.
