How clean label bread is made
Currently, there is no absolute definition for clean label bread or any other clean label baked goods. Instead, the clean label concept implies several aspects, including the following:2,3
- No added sugars, saturated fats and preservatives (e.g. sorbates and propionates) in product formulation
- Elimination of genetically modified ingredients (e.g. corn syrups)
- Use of natural and/or organic ingredients from sustainable farming (cane sugar, honey, milk, eggs, wheat)
- Use of tree nuts, whole grains, pseudocereals and ancient (heritage) wheats (e.g., Kamut, spelt, emmer, einkorn)
- Use of plant-based ingredients instead of animal-based
- Use of enzymes to replace oxidizing agents, mono- and diglycerides, and emulsifiers DATEM, SSL
Typical formulation of clean label bread
Ingredient | Baker’s % (based on flour weight) | Function |
---|---|---|
Wheat flour (white from hard wheat) | 85.0 | Gluten formation |
Whole wheat flour | 10.0 | Flavor and fiber inclusion |
Rye flour | 5.0 | Flavor and fiber inclusion |
Water | 43.5 | Hydration and dispersion |
Milk (pasteurized), cold | 21.0* | Hydration, flavor and nutrition |
Compressed yeast | 7.0 | Leavening, volume and texture |
Honey | 6.0** | Food for yeast and flavor |
Salt | 2.0 | Flavoring |
Vegetable oil | 2.0 | Lubrication and nutrition |
Phospholipase | ppm level*** | DATEM, SSL replacement |
Glucose oxidase | ppm level*** | ADA and potassium bromate replacement |
Ascorbic acid | 0.01 | Gluten network reinforcement |
Vinegar (11% acetic acid) | 2.0 | Natural preservative (mold inhibition) |
Total | 176.5 |
Total formula hydration: 63.0%
*Water content, 87%
**Water content, 20%
***Actual amount depends on enzyme concentration and activity
Processing
- Dough mixing: Incorporate dough ingredients at low speed for 2 min. Switch to high speed and continue mixing to full gluten development. This usually takes 8–12 minutes at a final dough temperature of 26°C (79°F).
- Makeup:
- Dividing
- Rounding
- Sheeting and moulding
- Panning
- Final proofing: Proof to reach ¾ full pan height at 38°C (100°F) and 75% RH. This usually takes 45–60 minutes.
- Baking (at sea level): Bake the product with the lid placed on top at an oven temperature of 200°C (392°F) for about 20 minutes to an internal temperature of 95°C (204°F). Thermal profiling is recommended for proper control and optimum quality. Bake time is usually longer than open top bread.
- Cooling: Remove product from pan and allow it to cool at room conditions to an internal temperature of 32°C (90°F). Cooling usually takes 60 minutes to reach final temperature.
- Packaging or serving
Application
Formulating a clean label bread requires a thorough understanding of the ingredients used, how they interact with each other, and how these attributes affect the finished product quality.
In real high-speed breadmaking conditions, clean label ingredients, especially enzymes, are required to meet or even exceed the functionality of traditional dough conditioners. Key functionality involves:
- Optimum gas production during fermentation stages
- Optimum gas retention through the formation of a strong gluten matrix capable of withstanding expansion
- Colloidal (foam) stabilization to prevent dough foam from collapsing during proofing or baking
- Crumb softening for expected shelf-life
- Mold growth inhibition
- Maintain previous product characteristics (pH, moisture content, water activity)
