"Gum arabic is taken from the sap of the acacia tree."

Indeed. Why? What's it for? What does it do? Properties, History... research!!!!

Aww, don't bite the newbies! It is a wiki, anyway, afterall :) Dysprosia 03:51, 5 Aug 2003 (UTC)

I changed the link to the mentos and coke experiment to point to a google video i found while researching the experiemnt because the link that was there wasnt working for me (it would load the page but not the video). Calebegg 23:02, 18 November 2005 (UTC)[reply]

Well, now that Google link itself doesn't appear to work. --Paulmoloney 14:15, 29 November 2005 (UTC)[reply]

Link should work. Thanks for noticing it. I'll edit it back in. Gee, I'm famous on the internet... -- The Linux Fairy (Joshua Wise)

The external link did not work so I pointed it to some random google video --Magicmasta 22:15, 9 June 2006 (UTC)--[reply]

"Mentos and coke" experiment explanation

I very much doubt that the surface activity of gum arabic has anything to do with its ability to nucleate carbon dioxide release from carbonated beverages. If this were so, dishwashing liquid should do at least as good a job, and probably a better one. Speaking as a scientist who has worked in this area, I believe that it is much more likely that the hydrophobic regions along the gum arabic molecule (which are responsible for its ability to stabilize emulsions through providing anchoring points to oil droplets) may act as nucleation sites for bubble formation.

Hi, I've started a page about this mentos experiment and added the scientific explanation provided on the science website ([1]) of the person who popularized the experiment. But I don't really understand the science behind it. Since you are a scientist you no doubt would understand it more than me. And it would be an honor to have you edit the page that I made Mentos eruption -Thanks

Snapple

Can anyone provide a date as to when Snapple changed their labels? Or even verify that they ever used the old name at all?

"Gum arabic is found in lemons." - um... is it? KLF Fitton 10:13, 12 May 2007 (UTC)[reply]

This is a fantastic article

This is by far, one of the funniest serious articles on wikipedia. The whole snapple thing... that cracked me up pretty good cause it so simple and stupid, but I guarantee it would have worked if it was ever really a problem in the first place. And then, it got even better. John Ukec Lueth Ukec was quoted at the Washington press conference, "I want you to know that the gum arabic which runs all the soft drinks all over the world, including the United States, mainly 80 percent is imported from my country," which he said after raising a bottle of Coca-Cola. According to the Washington Post, a reporter then asked if Sudan was threatening to "stop the export of gum arabic and bring down the Western world." To which Ukec replied, "I can stop that gum arabic and all of us will have lost this," and gestured to the Coke bottle. At that point, I just completely lost it for a good ten minutes. Thanks guys! —Preceding unsigned comment added by Momo Hemo (talk • contribs) 08:32, 16 October 2007 (UTC)[reply]

There is no Gum Arabic in any Cola, with the exception of Royal Crown (RC) which is the only cola to have it. Check the ingredients on all of the others). Barqs Root Beer also has it in it. —Preceding unsigned comment added by Sanford B. (talk • contribs) 17:46, 19 January 2010

Commercial plantations

I read in a book that it is commercially harvested from wild trees as the crop cannot be influenced by pruning, fertiliser or water (thus eliminating usefulness in plantation fields). Is this true ?, sounds odd.

The article on Mastix is awful, but do not merge it with gum arabic!!! They might occasionally get confused, but two are not the same! Mastix is the resin from a tree called Pistacia lentiscus, and gum arabic is made from the resin of two species of acacia tree. They have different properties, and are used for distinct purposes in the culinary and artistic fields.134.100.86.133 (talk) 13:29, 3 March 2010 (UTC)[reply]

Mastic (resin) it is not Gum arabic !!!

" Gum arabic " system made of acacia tree ! , And " Mastic " is made out of Pistacia lentiscus tree ! . Unfortunately many people in the world do not know this spice is known to only a few in the Middle East , And a secret except for people as a great healer. I ask not to be confused with Gum arabic is something else entirely! . " Mastic is made of wood and Pistacia lentiscus ". And Gum arabic is produced from a Acacia tree resin. This spice also does not appear in any dictionary in the world and the first time he appears in the encyclopedia That he always appears in the encyclopedia as a " resin of Pistacia lentiscus " . burekas (talk) 18:02, 3 March 2010 (UTC)[reply]

Mastic and gum arabic are indeed two very different substances, from different plants, with different properties and uses. Gum arabic is soluble in water, and once formed the basis for the glue on postage stamps and envelope flaps. It is also used in vernice bianca, which would not work at all if someone tried to substitute mastic for the gum arabic. Mastic finds one of its uses in drying-oil type varnishes incorporating, for example, linseed oil. Mastic is not soluble in water; in fact, a small piece of it makes a long-lasting chewing gum. With this in mind, I will boldly remove the merge tag on the mastic page, as not having a snowball's chance of passing. __ Just plain Bill (talk) 16:10, 7 March 2010 (UTC)[reply]

Mastic (resin) it is not Gum arabic

New entry "Mastic (resin)" has a suggestion to add the value into the value "Gum arabic". I want to say it's really not the same! , " Gum arabic " system made of acacia tree ! , And " Mastic " is made out of Pistacia lentiscus tree ! burekas (talk) 17:49, 3 March 2010 (UTC)[reply]

Gum arabic it is also a spice ? ...............

i ask, becouse moroccan jews put it in a " Almond nougat " that called : " jaban baluz ", and they eat this in the end of passover. burekas (talk) 09:54, 4 April 2010 (UTC)[reply]

I don't think so-- as far as I know, Gum Arabic is added for its effect on texture, not flavour. Beastiepaws (talk) 19:48, 4 April 2010 (UTC)[reply]

wrong page

^ See page 4 of the World Bank Policy Note, Export Marketing of gum arabic from Sudan, March 2007 - http://siteresources.worldbank.org/INTAFRMDTF/Resources/Gum_Arabic_Policy_Note.pdf

Toxicity?

Proposed merge with Pharmacognosy of Acacia (Gum)

This article is poorly cited but may contain some information relevant to a larger subject (that is, gum arabic itself) if reliable sources can be found. §everal⇒|Times 02:58, 17 February 2014 (UTC)[reply]

Merge any useful content of the pharmacognosy article into this article. The pharmacognosy article has/had multiple assertions of medical uses, without support in reliable medical sources. Kablammo (talk) 16:03, 17 February 2014 (UTC)[reply]

Weird grammar.

Placing an adjective after a noun is perfectly normal in many languages, e.g. in Polish: "guma arabska". But in English "gum arabic" sounds terrible. How about "arabic gum"? 85.193.232.158 (talk) 16:45, 1 December 2015 (UTC)[reply]

Usage as fuel charcoal is plain wrong... proposed removal

Having read the linked source (a paper about Gum Arabic in Morocco), it contains no mention of either Gum Arabic or the "taifa plant" being used to make any kind of fuel. With some limited googling, I couldn't find any mention of this either... not least because, as far as the internet knows, there is no plant called "taifa". Having not been able to find any sources to correlate the information in the section Gum arabic#Fuel charcoal, I believe the whole section should be removed.

This strange information seems to have slipped in a while back in a single edit (https://en.wikipedia.org/w/index.php?title=Gum_arabic&diff=prev&oldid=912166034) and gone unnoticed since then.

The source is still useful for the preceding section on pyrotechnics though. I have therefore added it as a citation in the pyrotechnics section and removed the "citation needed" tag.DigitalHamster (talk) 18:23, 8 May 2023 (UTC)[reply]
