Which ingredient is used to increase the dough’s resistance against over-proofing or anti-shock?
To increase the dough’s resistance against over-proofing (which can lead to volume loss, weak texture, or bread cracking), specific compounds known as anti-shock agents or dough stabilizers are used. These substances are generally classified as chemical or enzymatic improvers:
Common ingredients used to increase dough resistance against over-proofing:
- Ascorbic Acid(Vitamin C):
- Role: Strengthening the gluten network and increasing dough elasticity
- Function: Stabilizing the dough structure against over-proofing
Glucose Oxidase Enzyme:
- Role: Strengthening gluten by generating hydrogen peroxide
- Function: Improving dough resistance under prolonged fermentation conditions
- Calcium salts (such as calcium propionate):
- Role: Controlling yeast activity and slowing down fermentation
- Function: Preventing over-proofing and extending bread shelf life
- Emulsifiers (such as DATEM or SSL):
- Role: Strengthening dough structure and increasing final loaf volume
- Function: Preserving bread texture against thermal shocks or excessive fermentation
- Multi-Enzyme Systems:
Includes a combination of amylase, hemicellulase, and lipase.
- Function: Regulating enzymatic activity in dough to prevent structural weakening
Comparative Table of Anti-Shock Additives
| Additive | Type | Main Function | Effect on Dough Resistance |
|---|---|---|---|
| Ascorbic Acid | Chemical | Gluten strengthening | High |
| Glucose Oxidase | Enzymatic | Peroxide generation | High |
| Calcium Propionate | Chemical | Fermentation control | Medium |
| DATEM / SSL | Emulsifier | Dough structure strengthening | High |
| Multi-Enzyme Systems | Enzymatic | Enzyme activity regulation | High |
- Practical Notes:
- The exact dosage must be adjusted through laboratory testing on the flour being used.
- Enzyme combinations should be aligned with baking temperature and fermentation time.
- DATEM and ascorbic acid act synergistically, resulting in increased final bread volume.
- Malt powder not only nourishes yeast but also gives baguette crust an attractive golden color.
