Preservatives - S1.E2

In this episode Stefan looks at E number preservatives. He discovers one that keeps deadly bacteria out of our bacon, one that can double up as an explosive, and he even discovers an E number that the entire human race can't live without.

And in a true act of immersive reporting, Stefan even attempts to extract several E numbers from his own body. As if this weren't enough, he then makes a cake out of them.
