I'm sure by now most of us have seen the secret formula for Coca Cola, and I believe It's mostly right but maybe there may have been a few small
changes occur. Overall though I believe this to be the correct formula:
The secret recipe
* Fluid extract of Coca 3 drams USP
* Citric acid 3 oz
* Caffeine 1oz
* Sugar 30 (it is unclear from the markings what quantity is required)
* Water 2.5 gal
* Lime juice 2 pints 1 qrt
* Vanilla 1oz
* Caramel 1.5oz or more to colour (contains 4-methylimidazole)
7X flavour (use 2oz of flavour to 5 gals syrup):
* Alcohol 8oz
* Orange oil 20 drops
* Lemon oil 30 drops
* Nutmeg oil 10 drops
* Coriander 5 drops
* Neroli 10 drops
* Cinnamon 10 drops
Now the caramel contains 4-Methylimidazole, which recently caused controversy in the US as the particular chemical was found to be a possible
carcinogen, as well as already known beforehand as a convulsant. I believe though that the amount of Coke consumption needed to actually cause concern
would be about 50000 cans a day.
Still, it was deemed concerning enough that if the levels of 4-Methylimidazole weren't reduced, that the US would need a carcinogenic label on the
cans. The company complied and devised a new technique to reduce the amount of the suspect substance, although in Europe the regulations are different
and the original formula will continue in circulation.

I also want to talk about the teratogenic effects of caffine. Now although there is little evidence of a teratogenic effect from caffine on Humans,
the risk is potentiated with alcohol consumption.
The increased risk of the most common congenital malformations entailed by moderate consumption of caffeine is very slight. However, caffeine
potentiates the teratogenic effect of other substances, such as tobacco, alcohol, and acts synergistically with ergotamine and propranolol to induce
materno-fetal vasoconstrictions leading to malformations induced by ischemia. Therefore, even though caffeine does not seem to be harmful to the human
fetus when intake is moderate and spread out over the day, some associations, especially with alcohol, tobacco, and vasoconstrictive or anti-migraine
medications should be avoided.
Now you may think of teratology as physical abnormalities, but teratology can also include delayed mental development, without any structural
You might have seen in the ingredients, Alcohol. This is true.
In this case, Ethanol is used as the solvent to add the natural oils as they aren't miscible with the water.
If we look at the MSDS for Coca Cola we see this indeed true, approximately 0.1% alcohol is present in your Coke.

Although the content of some of the suspect substances are rather minute, the amount of Coca Cola that some people drink could be cause for concern.
With the combination of these ingredients being consumed in large quantities by some people, I believe the rise in related ailments to which I have
discussed are possibly due in part, to this beverage.
