Aside from the WTF level of this question. I have to say it seems rather bizarre to bother. I mean it isn't the most easy to calculate when you try to aim. I'd expect a lot of science would have to go into it before you ever launched the food into the mouth you were aiming at...
There's nothing particularly scientific about erection launching, simple recoil/catapault physics.
