If it's brown instead of red, it's either oxidized in some way or else has undergone a chemical reaction of some kind -- possibly acids reacting with metals -- don't eat it.
(And I won't be at Darkover after all; I hit my head accidentally last night and am having mild concussion symptoms, but enough that when I started to drive over this morning I only got to Laurel before I couldn't handle traffic and turned around. Am feeling fairly rotten about it.)
Ah. I think I can rule out reaction with metal in the instances I happen to have seen, but yeah, I can see why it might happen much faster in contact with metal. I wonder whether the plastic fast-food packets are slightly gas-permeable or something ... or maybe they have a small air bubble in them and there's just a higher percentage of the contents of the packet exposed to the surface of the air bubble than the percentage of catsup in a bottle exposed to the air above the level of the catsup in the neck of the bottle?
Sorry to hear about your injury and not coming to Darkover. My own attendance is now in question as well, because I can barely move and need to be on the road Real Soon Now if I'm going to get there in time for the things I was going for in the first place.
