What Is GAD (Glutamate Decarboxylase)?
GAD (Glutamate Decarboxylase) is an enzyme produced by certain strains of Lactic Acid Bacteria (such as L. brevis) within a sourdough starter. It facilitates the conversion of glutamate into GABA (Gamma-aminobutyric acid), a neurotransmitter associated with reducing anxiety and stress.
The Temperature Switch: Baking for GABA
The key molecule here is GABA (gamma-aminobutyric acid). It is the brain's primary inhibitory neurotransmitter, the biological "off switch" for stress and anxiety. And to maximise it in your bread, you may need to turn up the heat.
