I haven't been able to get a setting that works reliably. It is tied to the global spoil timer though, increasing that multiplier will increase the time of the dino consumables.
I don't really want to increase the default timer as I don't want players to be able to horde a bunch of these.
If I can get a setting working for it, I'd be more than happy to let admins choose how long the spoil timer is but unfortunately due to that being a core part of the item it's difficult.

thanks for your quick response!
