Talk:Blue corn

Blue corn pigment as indicator

   I'm pretty sure that

1. blue corn was human-bred, based the observation that those who planted it thrived somewhat more than others,
2. the observation was accurate, bcz the blue pigment serves as a pH indicator that food preparers use to judge when the proper amount of lime (Calcium hydroxide?) has been added in nixtamalization, and
3. using the amount of lime that produces the culturally accepted shade of blue serves to make one of the essential amino acids available, in the resulting baked product, to human consumers.

My stack is already too deep to commit, myself, to the research for fixing that; i hope a colleague will undertake it.

   I've just added to field corn a ref, the thesis of Jian Lin, which at p. 4 mentions "niacin bioavailability" as a benefit of the nixtamalization. That's a B vitamin, not an amino acid; that's probably what i misremembered about where the indicator's benefit arises. (A more directly focused source would make not just a more efficient, but also a more definitive, ref.)

Incorrect Photo?

The picture shows several ears of multi-colored flint corn. Unless I am mistaken, this is NOT the same thing as Hopi Maize. Hopi Maize is solid blue, with an occasional white kernel or ear. So-called "Indian Corn" is the multi-colored flint corn featured in this picture. This, I think, is misleading and will confuse readers about the appearance of Hopi Maize. I have some pictures that are of blue, Hopi Maize that will serve better. —Preceding unsigned comment added by 74.177.13.182 (talk) 16:11, 12 May 2011 (UTC)

Commercial Use

Hey I have a reference for the "Commercial Use" section, but being an ignorant peasant I don't have any idea how to insert it as a citation. It's an LA Times article, http://articles.latimes.com/1990-12-01/home/hm-5165_1_blue-corn . Veilen Dank! —Preceding unsigned comment added by 74.177.13.182 (talk) 16:24, 12 May 2011 (UTC)

Combine with purple corn?

Should purple corn be moved into this page? As the page states, purple corn is a bit of a misnomer, but its grown and developed in a geographically different area than blue corn. (Skoot13 (talk) 23:18, 16 July 2015 (UTC))

From what I've read on Hopi uses, they also had a deep purple/black corn, which fit in their color-direction framework of red, white, yellow, blue, purple/black, and multicolored ears of corn. There are signs of a similar system throughout Mesoamerica.

It seems that the choice is either to keep the colors separate, or provide an integrated discussion of colored ears of corn, including their cultural contexts. That would involve a lot of work since the color systems vary substantially among different tribes and, at present, Wikipedia only discusses blue and purple corn as distinctly colored.

I'd recommend keeping these two colors separate. --SteveMcCluskey (talk) 13:24, 17 July 2015 (UTC)

@Justlettersandnumbers: It seems that you've deleted, and prevented access to, every edit since 3 October 2012, including legitimate edits that were properly sourced. (I can't verify this since I can't access the removed material, but I did make some of the removed edits and they were legit.) Could you take a second look at your deletions to restore those edits which were not part of the copyvio problem. Thanks, --SteveMcCluskey (talk) 01:17, 11 June 2017 (UTC)

SteveMcCluskey, I certainly do understand that it could be an unpleasant surprise to find that one's bona fide good-faith edits have been hidden from view (and, I think, in this case deleted also). I'm sure you'll understand, though, that we can't leave copyright violations visible in the history for anyone to see; unfortunately, as here, there can sometimes be some collateral damage. The attribution for your edits is still in the history, but since (I think, I don't have admin vision) the edits were to a part of the text that turned out to have been copied from a blog, they are no longer in the article – obviously, that's through no fault of yours. I left the two references in place; may I suggest that the best way forward is to write new and better content based on what they say? Justlettersandnumbers (talk) 09:32, 11 June 2017 (UTC)
