I wouldn't involve real food in your presentation. It might get messy, you might be too nervous to swallow, you might choke, something else could go wrong.
Also, please be very very careful if you're carrying both a bow and arrows, and particularly if you actually nock an arrow. Shooting your audience is a bad thing! When I did a performance with a longbow, I didn't use arrows at all, and I won several awards for it. Pantomiming the arrow made me much more comfortable.
