8. Wheat Flour
*Principal ingredient in Bakery products.
*Unique ability to form Gluten.
*Gluten is made of Gliadin & Glutenin (Insoluble Proteins).
*Soluble proteins present in wheat flour are Albumin & Globulin.
*Gluten is elastic–like and forms matrix.
*Gluten forms only on mixing with water.
*Gliadin contributes to elasticity & Glutenin imparts strength
(Resistance).
*Both quantity & Quality of gluten are important in assessing
the strength of flour.

9. WATER
*2nd major ingredient in Bakery products.
*Hydration of proteins.
*Acts as a dispersion medium for sugar & other chemicals.
*The consistency of dough largely depends on water.
*An excellent leavening agent.
*Medium hard water is preferred for most of the Bakery
products, as some of the mineral salts (like Calcium salts)
have a strengthening effect on gluten and some (like
Ammonium salts) serve as yeast foods.

10. FATS & OILS
*
*Act as lubricants.
*Tenderizing agent.
*Provides texture/structure to the product.
*Act as aerating agents.
*Eating quality (Palatability).
*Moisture-barrier in finished products.
*

11. SUGAR
*Particle size of sugar greatly affects baking properties.
*Gluten Development.
*Leavening.
*Creaming.
*Gelatinization.
*Caramelization.
*

12. SALT
*Preservative.
*Texture aid.
*Binder.
*Fermentation Control.
*Flavor Enhancer.
*

13. MILK & MILK PRODUCTS
*Flavor and taste contribution.
*To enhance crust color and bloom.
*To improve tenderness of the product.
*To improve the texture without altering the symmetry and
crumb color.
*To reduce the greasy feeling in sandwich creams.
*As an alternate to eggs (use of whey protein concentrates).
*

14. FLAVOURS
*Taste enhancer
*Dispersibilty in water or fat as per requirement
*Expression/Stability at the product pH.
*Compatibility to the product as the expression of flavor
generally varies with the fat content in the product.
*Masking any undesirable odour from the product.
*Closeness to the natural product envisaged.
*

15. COLOURS
*To provide identity to the food product.
*To provide variety to the consumer.
*To correct the natural variations in the color of the food.
*To enhance the natural color but at levels lower than that
usually attached to the given food.
*To protect food products, flavors and vitamins that can be
affected by exposure to light.
*

16. EMULSIFIERS
*Starch complexing (anti-staling)
*Protein complexing (Dough strengthening)
*Viscosity modification
*Foaming and aeration
*Texture modification
*Lubrication
*Crystal modification
*As Wetting agents & solubilisers.
*Suspension & dispersion.
*

17. LEAVNING AGENT
*
*Rise the volume of dough
*Baking powder contains baking soda and the right amount of
acid to react with it.
*Batters made with double acting baking powder rise twice;
*once when dry and moist ingredients are mixed together, and
again when the product is baked.
*
1-S.B.C.(Sodium bicarbonate)
2-A.B.C.(Ammonium bicarbonate)

18. Above 70 °C, it gradually decomposes into sodium carbonate,
water and carbon dioxide. The conversion is fast at 250 °C
2NaHCO3 → Na2CO3 + H2O + CO2
Leavening agents where in application low final moisture
content is reached in baked products such as cookies and
crackers.
NH4HCO3 → NH3 + H2O + CO2

34. CONTINOUS MIXTURE
Mixing time is around 2 min.

35. Benefits of Continuous Mixing
*Simplifies the mixing process
*Disperses ingredients consistently
*Simplifies dough feed equipment
*Provides tight control over the mixing process
*Is safer , more sanitary and can be operated with less labour
and energy than batch mixing
*Is easy to sanitize, maintain, clean and inspect due to the
clamshell design
*No dough contamination because the dough is never exposed
to the environment
*Is easy to operate due to the user friendly controls
*Controls ingredient metering to the mixer so it’s precise and
uninterrupted.

39. BAKING
The zones are classified as:
There are 7 independent zones in all three plants. These
are
a) Proofing zone: zone 1 & 2 (Structure is set here)
b) Puffing zone: zone 3 & 4 (Product get oven spring)
c) Baking zone: zone 5 & 6 (Moisture removal of product)
d) Colouring zone: zone 6 & 7 (Millard & Caramlization)

40. The Physical changes
The Chemical changes
• Large reduction in product
density.
• Development of an open
porous or flaky structure.
• Change of shape associated
with shrinkage or spread
and increase in thickness.
• Reduction in moisture level,
to between 1-4%.
• Change in surface
coloration (reflectance).
•

for natural cooling prior to
packaging. The temperatures
are brought down to room
temperatures. It should
between 35°- 40°C.
