Using the power of science, 'Coca-Cola' has been almost perfectly recreated, and the recipe has been released. Those who have tasted it have praised it, saying, 'This is Coca-Cola!'
Science YouTuber LabCoatz has released a video in which he claims to have created a Coca-Cola that is so precisely made it indistinguishable from the real thing.
The Coca-Cola recipe is kept strictly confidential, and even within the company, only executives are allowed to know it.
LabCoatz decided to use the power of science to unravel the Coca-Cola recipe. First, most of the ingredients can be easily determined without complex analysis. One liter of Coca-Cola contains 110g of sugar, 96mg of caffeine, and 0.64g of phosphoric acid.
It also contains caramel coloring, which gives Coca-Cola its dark brown color and includes important flavor components such as furfural.
The secret to Coca-Cola lies in the composition of the remaining 'natural flavorings.' LabCoatz used mass spectrometry to analyze the actual components it contains. In mass spectrometry, Coca-Cola is first separated into its components using chromatography.
Next, energy is applied to the separated substances to ionize them, and their components are identified by observing the differences in how they bend under magnetic force.
The analysis results are as follows. The highest peak is
Limonene, 3-carene, fencol, 4-terpineol, and cinnamaldehyde were also detected.
Based on the analysis results, LabCoatz combined various essences to try and contain equivalent substances, but he couldn't get rid of the 'slightly different' result.
After much trial and error, LabCoatz realized that 'coca leaf extract is essentially tea.' Tannins are extracted along with the coca leaf extract, but since tannins do not volatilize, they could not be detected by gas-based mass spectrometry.
The mass spectrum of 'Lab Cola,' made using LabCoatz's method with added tannins, is shown below in comparison to that of the real thing. The top is the real thing and the bottom is Lab Cola, and you can see that the results are almost identical.
LabCoatz himself felt that the result was 'closer to Coca-Cola than Diet Coke.'
When several people tasted the drink, those who regularly drink Coca-Cola could tell the difference, but they all agreed that it was 'almost certainly Coca-Cola.'
The specific ingredients and instructions are explained starting around
