16 Questions
What is the primary purpose of the autolyse process in dough development?
To improve gluten structure properties
What is the minimum time required for the autolyse process to be effective?
15 to 20 minutes
What is the role of proteases in the autolyse process?
To degrade protein bonds
What is the effect of yeast on the autolyse process?
It increases the acidity of the dough
What is the benefit of autolysing only a portion of the dough?
It enables the baker to get the benefits of autolyse without interrupting the mixing process
What is the effect of salt on the autolyse process?
It slows down the action of proteases
What is the definition of extensibility in the context of dough?
The ability of the dough to elongate easily
Who is credited with developing the autolyse process?
Raymond Calvel
What happens to the proteins of the flour during the autolyse process?
The proteins of the flour become better hydrated, leading to better gluten structure properties of strength and gas retention.
What is the natural action of the enzyme protease in the autolyse process?
Proteases are responsible for protein degradation, and they will react on the protein and degrade some of the gluten bonds.
Why is it necessary to add yeast, salt, and stiff preferments to the dough after an autolyse?
Because yeast, salt, and stiff preferments work to counter the effects of the autolyse, with salt slowing the action of proteases and yeast creating acidity that increases dough strength and decreases extensibility.
What is the advantage of autolysing only a portion of the dough?
It allows the baker to get the benefit of the autolyse without having to stop the mixing process to wait for the enzymatic activity to happen.
How does the autolyse process impact the machinability of the dough?
The autolyse process improves the machinability of the dough by making it more extensible.
What is the relationship between the autolyse time and the activity of the enzymes?
A minimum of 15 to 20 minutes is necessary to provide sufficient time for the activation of the enzymes.
How does the autolyse process impact the final texture of the bread?
The autolyse process can lead to a lighter, airier final product due to the improved gluten structure and gas retention.
What is the significance of the enzymatic activity during the autolyse process?
The enzymatic activity breaks down some of the gluten bonds, making the dough more extensible.
Study Notes
Autolyse Process
- Developed by Professor Raymond Calvel, a French Master Baker
- Involves mixing flour and water, then resting for a minimum of 15-20 minutes
Reactions during Autolyse
- Proteins in flour become better hydrated, leading to better gluten structure properties (strength and gas retention)
- Natural action of protease enzyme, present in flour, degrades some gluten bonds, making dough more extensible and improving machinability
Enzymes and Proteases
- Enzymes are organic components with specific and natural actions of degradation
- Proteases are responsible for protein degradation and are present in flour
Autolyse Timing
- Minimum of 15-20 minutes necessary to activate enzymes
- Can last up to 1 hour for bulk of dough
- Alternative: autolyse only a portion of dough (with a portion of flour) for a longer period (8-12 hours or overnight)
Autolyse Benefits and Limitations
- Allows for better gluten structure and more extensible dough
- Yeast, salt, and stiff preferments are added after autolyse, as they counter its effects
- Salt slows protease action, while yeast fermentation creates acidity, increasing dough strength and decreasing extensibility
