Caffeine Measurement in Foods – It’s too Hard!

posted in: General Technology | 0

I have an idea; it’s not very complex; it’s something I could create myself; but for one stumbling block.  How to measure the caffeine content in foodstuffs.

Admittedly, I’ve only done a few hours of research on the Internet, but it appears there is no home-use caffeine content measurement procedures.  There currently seems to be two primary methods; neither of these are accessible to the average home user.  There also seems to be a traffic light type test that is currently being developed, but this won’t suit my needs.

The most common of the two methods is high-performance liquid chromatography (HPLC) and uses UV absorption to determine the caffeine content in a liquid.  When caffeine is present in a liquid the 205 nanometre and 273 nanometre wavelengths are absorbed.

I’d love to see a user-friendly device or test that can accurately report the caffeine content in food.
