What is Autolyse?

The Definition

Autolyse is a baking technique that involves mixing flour and water and allowing them to rest before adding salt, starter, or other ingredients. During this rest period (typically 30–60 minutes), two key biological processes occur: enzymes (amylase and protease) are activated to break down starch and protein, and the flour fully hydrates, improving dough extensibility.

The Science: Passive Development

Think of autolyse as "enzymatic pre-digestion." When water meets flour, it acts as a trigger for biological activity.

  1. Protease Activity: These enzymes begin to degrade the protein bonds. While this sounds destructive, it is vital. It softens the gluten network, increasing extensibility (the dough's ability to stretch without tearing).

  2. Amylase Activity: These enzymes break down damaged starch into simple sugars. This provides an immediate fuel source for the yeast once the starter is eventually added.

The Protocol

  • Standard Duration: 30–60 minutes.

  • When to use: Essential for whole grain flours (which absorb water slowly) or high-protein flours (which can be bucky or tough).

The Result: A dough that requires less mechanical mixing (kneading), preserving the carotenoid pigments responsible for flavour and crumb colour.
