Pepper extract in food?

Hi all, what is pepper extract that you find in food? What I mean is, what kind of pepper is it? Is it black, white, bell pepper, chilli pepper or what? I'm deathly allergic to bell peppers so I need to know before I eat anything with it in. It's in the beef stock with the yeast and salt, so I would assume it's black of white pepper, but I need to be certain first. I don't want to eat it and risk it being bell pepper extract, I don't fancy death any time soon! Thanks in advance.
