Ingredients of All-Natural Blueberries

There are now 20 graphics on my to-do list. I’ll probably make about 5 of them, and only one or two of those will be any good. 😛 (Making graphics is a bit like taking photographs—you take 1000 photos on holiday, delete 500 and put no more than 6 on your wall.)

The Table of Esters and Their Smells did surprisingly well. It got over 2,000 downloads on its first day. 🙂

The graphic below is a follow-up to Ingredients of an All-Natural Banana. To make these graphics, I calculated the percentage composition of all the interesting ingredients and wrote an “ingredients” label for each fruit using E-numbers where they exist. Anthocynanins, which are said to give blueberries their “superfood” status, are also known as E163, for example.

As a Chemistry teacher, I want to erode the fear that many people have of “chemicals”, and demonstrate that nature evolves compounds, mechanisms and structures far more complicated and unpredictable than anything we can produce in the lab. Enjoy!

I like the “fresh air” at the end. Nitrogen is E941, Oxygen is E948 and Carbon Dioxide is E290. (Argon, which comprises about 1% of the air we breathe, also has its own E-number: E938.) Thousands of minority ingredients including DNA have been omitted for brevity’s sake.
