Day 5
• Dough technology
• Sourdough cheese
• Potato bread
• Formula Development
Dough Conditioners
• IMPROVERS
• Oxidizers- Improve gluten
• Reducing agents- Improve extensibility
• Emulsifiers- Bond water to other molecules
• Enzymes- Catalysts
• Vital wheat gluten- Added to weak flour
• Yeast nutrients- Added to no time conditioners
• Fillers- Bulking agent
Oxidizers
Reducing Agents

Emulsifiers• What? Emulsifier will assure optimal
mixing of fat and water.• They are able to link waterloving and
fatloving parts of the gluten chains, so a better developed gluten network is obtained.
• 2 types:– Dough strengtheners– Crumb softeners
Enzymes
• Affect starch, proteins and fat
• Break larger molecules into smaller ones
What are Enzymes?• not alive, can not move • ° does not reproduce itself• ° all enzymes = proteins; all proteins ≠ enzymes• ° biocatalyst = speeds up (or slows down)
chemical reactions • ° specific activity • * Amylase ---------> Amylum (starch)
* Protease ---------->Proteins
• * Lipase ------------>Lipids (fat)
• ° activity = (T, pH, t) • ° Used for food, non-food and pharmaceuticals
Uses for Enzymes
Stabilize variation in wheat quality
(type & climatological) main ingredient of a baked product is also the most variable one!
Balance existing enzyme activities Volume, softness, dough handling,
shelf-life...
Sourdough
• Use natural starter to make levain
• Acid creates flavor/ preserves
• Somewhat denser grain than yeasted breads
• Better if bread is retarded- long fermentation
• Uses stiff starter
Sourdough Cheese
• Asiago and other hard cheeses added for strong flavor
• Solids- No more than 50%
• Rye flour?
Potato Dill Bread
• Potato starch retains moisture= softer texture
• Dill- mild herb
Final Formula Development• No more than 1100g finished dough- 2
breads
• Start with Final Dough percentages
• Determine % of pre-fermented flour- 10-25% max
• Must be sour dough from starter
• Present draft on Thursday
• Formula development sheet for each iteration
• If you need any ingredients- let me know
Formula development
• Do at least 1 formulation/day
• Can vary flours and starters, vary % of starter and pre-ferment flour
• Finished bread to be presented Day 14
• Final paperwork due Day 14
• If you are using a variation of a bread, you must reference that bread and make substantial changes
Today’s Production• As per Production Schedule
