Ingredients of an All-Natural Coffee Bean

Following last week’s Starbucks® graphic, it seems right to follow up with a quick poster on the Ingredients of An All-Natural Roasted Coffee Bean.

The Ingredients poster series was featured in Forbes last week (article written by Robert J. Szczerba, CEO of X Tech Ventures).

Follow me on Twitter (@VCEasy) to see all the latest posters (unfinished ones included!)

If Beetroots had Ingredients Labels…

It’s Australia Day and beetroot burgers are in ‘season’.

Chemically, beetroots are remarkably simple.

ingredients of an AUSTRALIAN BEETROOTThe colour in beetroots comes from just two E-numbers (which are each groups of about 10 compounds); and the flavour comes almost entirely from geosimin. So simple.

Happy Australia Day!

Meet the Terpenes: A Visual Introduction from Isoprene to Latex

Inspiration for Meet the Terpenes came from the rhetological fallacies graphic over at Information is Beautiful, while motivation came from a 45°C heat wave this week that prevented any sensible Australians from going outside. So I stayed at home and did this.

It took about three days to sketch, research and create.

Three days ago, I knew nothing about terpenes. My undergraduate phytochemistry class was really difficult. The teacher was a genius, and put huge amounts of effort into his tutorials, giving us thick booklets at each seminar filled with his hand-written notes and dozens of chemical structures. But for some reason, I just didn’t get it.

So this week, I decided to make the graphic I wish I’d had when I took the phytochemistry class many years ago. Having this poster on my wall would have answered all my questions and made the class much more enjoyable. I hope you find it useful, too.

As always, I welcome all feedback, corrections, suggestions and comments, etc.

Enjoy 🙂 James

Infographic: Table of Esters and their Smells

Table of Esters and Their Smells

I love esters. This infographic is totally self-explanatory to any chemist. (Or email me if you have any questions.) Enjoy! 😉

  • Esters are made by reacting alcohols and carboxylic acids together in a condensation reaction.
  • Different combinations of alcohols and carboxylic acids give rise to different esters, and each ester has a unique aroma.
  • These esters are found naturally in fruits and vegetables and are also used in perfumes.
  • You can now look up an ester in the table above and find its aroma by referring to the picture.
  • Ambiguous or “mixed” smells are indicated by the presence of multiple images in each box.
  • Benzyl salicylate is amazing: some people can perceive it while others can’t. However, people who can’t perceive benzyl salicylate can tell that it alters the overall aroma of perfume to which it’s been added! Magic!
  • You can make any of these relatively safely in the kitchen or at school.
  • All of these esters are edible in minuscule (microgram) amounts and are found naturally in all fruits, vegetables, herbs and spices.
  • That said, though,
      never eat anything you make in the lab!
