It’s so delicious, other foods

are made better by adding bacon.

You can even wash your body in bacon.

But there’s something else that makes bacon

the best breakfast food out there:

the smell.

Throw some bacon into the pan,

and as soon as the sizzle starts,

people are flocking to the kitchen…

but why?

Our friend over at “compound interest”,

a chemistry blog, broke down

the aroma science for us.

Turns out there are about *150* organic compounds

that contribute to the sweet smell of bacon.

See, when you throw it in the pan,

sugars react with amino acids in the bacon.

It’s called the “maillard reaction”

and it’s basically what causes anything you cook

(steaks, breads, dumplings, etc) to turn brown.

For bacon, the maillard reaction combines with

melting fats to produce the aroma compounds.

What are they, you say as you get hungrier?

About two thirds of the compounds

are hydrocarbons and aldehydes.

Hydrocarbons are just hydrogen and carbon atoms

chained together in thousands of different ways.

Some of those chains just happen

to produce a pleasant odor.

Aldehydes are equally simple.

They still have carbon, but they bond

with oxygen as well as hydrogen

and some produce a lovely smell.

But it may just be nitrogen-containing

compounds that make bacon smell

like nothing else in the universe.

These compounds are called pyridines and pyrazines,

which put off smells of their own.

Pyridines in bacon contribute to its “meaty” aroma.

But combine them with hydrocarbons

and aldehydes and they become

the major contributor to bacon-y goodness.

So there you have it.

150 compounds all mixing together in

a pan to make bacon smell delicious.

Maybe you like hot sauce on your bacon.

Maybe you’re allergic to it

(which would be awful).
