L-Cysteine From Hair

How L-Cysteine is derived?

This one is really crazy food fact! Did you that the L-Cysteine a common ingredient in the bread is actually derived from human hair?

It is a non-essential amino acid added to many baked goods as a dough conditioner in order to speed industrial processing.

It’s usually not added directly to flour intended for home use. While some L-cysteine is directly synthesized in laboratories, most of it is extracted from a cheap and abundant natural protein source: human hair.

The hair is dissolved in acid and L-cysteine is isolated through a chemical process.

Other sources of L-cysteine include chicken feathers, duck feathers, cow horns and petroleum by products!!

Is it good or bad you decide!!!
