Coca-cola are under fire for claiming that caffeine “adds flavor to cola”.
A study published in the journal Appetite shows that people cannot tell the difference between a decaffeinated cola and one spiked with caffeine.
In the study, outlined in the American journal Appetite, 30 people were given three small cups of commercial decaffeinated Coke.
Researchers spiked one sample with caffeine and asked participants to spot the difference. Nobody could tell the difference in repeated tasting. (via The Age)
The study author claims it is “unethical for companies to use caffeine if it did not enhance flavour and could lead to young people becoming addicted to sugary drinks”.
The intriguing thing is that the subjects in the study could detect the caffeine in a very sweet solution.
