Black stuff in peanuts

December 10, 2007 8:28 PM

What is this black, salty, bug-eggy powder that I find in about 1 of 10 peanuts when I crack them open?

I generally enjoy salty stuff, but the possibility that these are bug eggs sorta disgusts me. Can anybody shed some light on this?

One in ten from the same source? Or just generally?

A list of peanut diseases here, FWIW.

Gah, I hate to cry wolf, but if I were you I wouldn't eat those.

Disclaimer: I am not a peanut farmer - all links via Google. Peanut pests doesn't have any mention of the laying of eggs inside the peanut. I suppose it could be a mould, maybe Sclerotinia minor (from here) or Aspergillus Niger. Enjoy ;-)

I can't find sources, but usually it is just char from being at the bottom of the roaster.

Response by poster: Thanks folks. Yes, consistently over the years from different sources. It's probably not char from the roaster because the particles are round ("eggy") and located *inside* the peanut.

Probably, as tellurian guesses, a mold.
