It's even worse than that. The makers aren't even sure what was in their product to begin with.

Zahn says the kokum butter shouldn’t be an issue anyway: The company has since replaced it with cocoa butter, which does have GRAS certification. Initially, he told the Post the cocoa butter version was what he submitted for the awards, but after this story was published he said he determined that it was in fact the kokum butter version. (According to Weiner, Climax submitted an ingredient list that included kokum.)

So it might have been labeled with having kokum butter, it might not. Who knows? Seems to depends what answer is needed at the time.

Also,

Climax, it turns out, wasn’t just a finalist — it was set to win the award, a fact that all parties are asked to keep confidential until the official ceremony in Portland, Ore., but was revealed in an email the foundation sent to Climax in January.

If I'm reading this correctly, out of all the contestants, only they knew they won. Makes it a further stretch that it was a dairy company that "out" them as they wouldn't have known that the vegan cheese won.

My guess for the change about GRAS was it most likely was assumed everyone would only submit GRAS items, and since someone broke that non-spoken rule then they had to make it a clarified rule. It is something you'd just assume everyone made sure their food was most or less FDA approved (which is a logical assumption).

The Washington Post article is much clearer about this whole issue (which is linked to in this badly written Boingbonk article.)

Kokum butter is edible and occasionally used to make chocolates and other confections.

Here are more details (and more context is in the article):

"Someone had tipped off the foundation on something that disqualified Climax, Good Food Foundation Executive Director Sarah Weiner told the Washington Post. The complaint potentially arose from Climax’s use of the ingredient kokum butter, which has not been designated as GRAS (generally regarded as safe) by the Food and Drug Administration. However, Zahn told the Washington Post that the company has replaced the ingredient with cocoa butter, which was the version he said he submitted for the awards (although Weiner contests this).

The Good Food Awards also didn’t require GRAS certification for all ingredients back when contestants submitted their products — rather, the foundation added this to the rules later on. Zahn claims the Good Food Foundation never reached out to Climax to inform the company of the new requirement, although Weiner told the Washington Post it attempted to. SFGATE could not reach the Good Food Foundation for comment in time for publication.

“It would have been very easy for them to reach out to us and tell us about the new requirements,” Zahn told SFGATE. “… The thing that’s upsetting to me is that they were kind of unprofessional by changing the rules a week before the event.”"

There are innumerable horror stories from cottage vendors bumping up against the money and strict gatekeeping of the nationally established conglomerates. This was in the US, but I know Canada also has, new, laws on the books to specifically prevent plant based cheeses from referring to their product as "cheese," despite being the exact same process and a final product that you wouldn't know side by side to the dairy version.

I'm not a vegan, but this is the just same ole regulatory capture bullshit that we're seeing w ev cars, good imported rum, net neutrality and everything else
