It seems that the coloring used in the haw flakes was Ponceau 4R (E124, Acid Red 18). We need a Wikipedia article about this chemical. Badagnani01:56, 18 March 2007 (UTC)[reply]
Right but Ponceau S and Ponceau 4R aren't the same chemcial. I changed the Ponceau 4R link in the see also to the Ponceau disambiguation page. I'll go ahead and remove this from the food additive stub category unless someone coughs up a link suggesting Ponceau S has shown up in food. Just speaking from personal experience in the laboratory, it's not thought to be terribly hazardous. You probably shouldn't ingest it, but this is true of almost everything in a laboratory setting. --SquidDNA01:48, 3 July 2007 (UTC)[reply]
What colour does it have? I would assume pink or red. Anyone can confirm? I will add to the article, see the older image on the bottom left. 84.112.136.52 (talk) 20:30, 6 October 2013 (UTC)[reply]
It is more reddish than pink in my experience. I remember in a practical course, though, it was said that the longer the gel is stained with Ponceau S, the darker the gel will turn, so perhaps one needs to also provide the amount of time for staining procedure used, when one shows such pictures of Ponceau S staining. 04:50, 24 July 2017 (UTC)
Which 'TCA' is being referred to here? The link goes to a disambiguation page, but more than one chemical is listed: thus, still ambiguous. 131.104.115.9917:31, 6 July 2007 (UTC)[reply]

Can someone add a sentence about this? I remember that Coomassie is used more regularly because the bands are visually easier to spot. I do not know whether this is true or not but if so, then I think it should be mentioned. 2A02:8388:1602:A780:3AD5:47FF:FE18:CC7F (talk) 04:51, 24 July 2017 (UTC)[reply]
