Fermentation

Fermentation is in general food processing by micro-organisms. Pasteur defined it as ‘respiration without air’. In a way fermentation is the opposite of respiration. Your muscles ‘ferment’ when exercising!

Fermentation consumes carbohydrates without air into organic acids. Instead of going into the Krebs-Cycle and reacting with oxygen, it goes a different pathway. The low pH protects the food against pathogens, disease-causing bacteria. So this is why it was utilized so often before the refrigerator in ancient times.

The relevant micro-organisms are:

  1. Yeasts, they produce ethanol. (Bread, beer, wine)
  2. Lactic acid bacteria produces lactic acid. (Milk, cheese, soy)
  3. Acetic acid bacteria produce acetic acid. (Vinegar)

Cheese is made by denaturalisation of proteins by acid produced by fermentation!

The BigMac metric system

A BigMac

By comparing the cost of BigMac’s around the world, you can get a fun way to compare economies of countries. This is called the BigMac-index. You use the BigMac as a standard to compare stuff too.

According to this webpage, the sun radiates heat energy equal to 170133333333333333333 Big Macs. That is 0,17 thousand trillion Big Macs!

If you fuck around with the units, you can get ridiculous sentences like, it takes 2,25 microBigMacs per meter to lift your car keys. Very clarifying. You can still make a bit sense of it if you picture that you need to consume a bit more than two microBigmacs to lift a car key over one meter.

Even more ridiculous is that the Eiffel tower is 44 nanoBig Macs kilogramseconds squared/per meter tall. What the fuck? It is correct scientific terminology though.
