Gum Arabic - last ingredient for open cola eludes me

[Tamsyn Michael]

I've got all the ingredients bar this one.  Apparently used in cake baking?
http://en.m.wikipedia.org/wiki/Gum_arabic#section_1

Any tips on where to get it?

[Kim Hawtin]

Australia 5000

Thanks Kim, but art-grade is the wrong gum Arabic.  Food grade is non-toxic.  :)

I was gunna say!
Must be a different kind of thickener, the gum arabic I've used for binder is dissolved in alcohol.

Now that'd make for some great cola!

Seems to be something stocked by baking/cake suppliers;
http://bakingpleasures.com.au/p278/gum-arabic
http://www.mfcd.net/store/product.asp?pID=646&c=122020

Can't locate one locally though...

[Andrew Helgeson]

Yep!
Bit more "kick"!

We need to put the coca back in cola!

Andrew

[Tamsyn Michael]

Hehe - thanks all.  I found the gum arabic (and the caramel colour) at Caroline's Cake Supplies in Oaklands Park.  The dude even through in the citric acid (100%).  Thanks for the cake supplies tip Kim.

Now all I have to do is source the caffeine :/ - I figured that'd be a trip to the chemist, but I'm not sure how many mg of caffeine are in 1 mL, and no doz is expensive.

$20 for 20g or $69 for 100g.

There are cheaper suppliers from the US (smartpowders - 400g for $13) but I presume you don't want to wait for shipping.

Also, be very very careful with this stuff - buy a scale accurate to at least 10mg, and measure twice. Also don't divide up the 20g package assuming that they've actually given you 20g - sellers can sometimes be 'generous'. Store it out of sight too, lest someone unaware decides to take a spoonful of it...

[Andrew Helgeson]

20g in a litre!!!!
Are you going to substitute phosphoric acid with citric?

won't be the same....

:-)

[Tamsyn Michael]

Thanks - I may try that for next time.  But I did the math, and no-doz is actually not to bad / mg of caffeine.  Much cheaper than Coke.  :)  I should probably switch all together.  Have half a tablet and a bottle of water instead...

After I try this.  Wish me luck, I'll be mixing it up while dinner's cooking.  If anyone wants to try it (and I don't fail miserably) I'll bring the syrup and a bottle or two of carbonated mineral water to Hackerspace.

[Steven Pickles]

Are you doing the full hammer-drill-powered-whisk? This is one of the crucial things that the Cube Cinema folk discovered when trying to execute the open cola recipe (check out Cube Cola). You need high sheer strength to get the gum arabic to form an emulsion, hence the Tim-The-Toolman style mixer.

... or you can use 30mL of water in the oil mix instead of 3 :).

Yeah - saw the cube cola recipe.  I'm hoping my blender will do the job though.  Damn the oil mixture smells good.  I'm seriously thinking of making an 'eu de coke' perfume.

[Damien P]

Are you going to carbonate it with something like this:

http://www.thinkgeek.com/product/c908/

[Tamsyn Michael]

Hehe Damien - awesome.  I haven't seen that before.  Nice use of science.  I'm using carbonated water from the supermarket though.

And it tastes nooooothing like coke.  Too sweet (I didn't think it was possible) and orangy.  And it's red.  I think I'm enjoying it, even if it is like swigging perfume, doubt I'd make it again except to wear on a date.  I tried a little of the emulsion in water.  It was much better without the sugar (though I'd probably miss the caffeine).

I'm looking forward to others' opinions on this one.

Oh, and after all that worry the caffeine was super easy to work out - Coke is 100mg / litre so I crushed 25 tablets - they dissolved fine in the hot liquid.

Cost

Oils - $9.00
Caffeine - $5.00
Colour - $3.35
Thickener - $1.80
Total - $19.15

80c a litre - the same as generic cola.

I wish it wasn't so sweet - I am thinking of adding a little more acid - I'll see what you guys think first though.  :)

[Tamsyn Michael]

Oh, damn.  I tried just adding some more acid to the glass and now I know what it reminds me of...  Berocca.  Anyone want a caffeinated berocca mix with none of those pesky vitamins?

[Andrew Helgeson]

The too sweet is no phosphoric acid, why pepsi is the devils cola!

I saw Cube Cola give a presentation (quite) a few years back. Their result was in the ballpark of Coke, and it certainly wasn't red. They did a blind taste test with a bunch of cola-clones to see if your taste preference aligned with preference of the cultural views of each cola (eg, Mecca cola and Turka cola). Spoiler alert, it didn't ;) Coke has a much rounder flavour than most of the clones.

Coke is the only cola that doesn't taste sickly sweet - I'm guessing it's the acidity.  Also coke is way more carbonated than other colas (which would add to the acidity even further).  I kind of wish I had left out some of the sugar.  Did the cube cola taste sweeter than coke?

:( - I done fucked up - I don't think even super carbonated water can save this.  :)

[Andrew Helgeson]

Wonder where you would get phosphoric acid?
Or what percentage

Last time I saw it for sale, it was being used as a rust treatment.
Most emphatically not food grade.
