Baking Theory Notes: Cake Baking and Ingredients 6

It all started as...
----->Bread dough enriched with butter and spices, leavened with yeast and air was whipped into the dough.

----->ca. 1837 : Baking Powder revolutionizes cake industry (allows for consistent leavening)

Characteristics of Cakes:

*Pound / White / Yellow

  • Batter - high ratio cake (fats) , Chemical leavened.


*Angel Food


  • Foam - Air leavened, uses whipped egg.


*Chiffon

  • Combo of Batter & Foam - whipped eggs added to batter


Ingredients:

  1. tenderizers
  2. moisteners
  3. flavorers

*Flours Used in Cake baking
  • Mainly cake flour (7-9% protein, soft milled)
  • Can use AP, Pastry,
Why Specific Protein Count needed, how it forms Gluten Structure:
  1. Bleached flour (has carotenes taken out)
  2. Flours are Made with Matured Wheat - if using a heavier protein percentage (i.e in bread flour etc, will cause cake structure to become dense, unstable and collapse into it's self.
  3. Moisture content comes from the flour

*Sugars Used in Cake Baking

What sugar does for cakes:
  1. Acts as a Sweetener
  2. Extends the shelf life of the cake
  3. Aides in creaming (process of whipping air into the batter)
  4. Gives cake crust it's color
  5. Spreading action (the process of melting during bake off)

Dessert Costing : Banana Strawberry Torte 3

This post is referencing a previous post dated Feb. 11 2008 : Food Photography : Strawberry Banana Torte

So David here are those details, as promised. I created this post using Google Docs. Google Docs rocks my blogger socks off! I can just click a button and post a nicely formatted post. I plan to use this tool more in the future.

The purpose of this post is to show you readers how to find a base cost for a plated dessert and what goes into those calculations


Costing Formulas:

☆ Ingredient weight (divided by ingredient unit cost) = ingredient cost per lb/oz
☆ Ingredient cost per lb ( divided by number of oz) = cost per oz
☆ Ingredient cost per oz/lb multiplied by formula ingredient weight = final ingredient cost. ☆ Final ingredient costs added together = total dessert cost
☆ Total dessert cost ( divided by dessert serving number / weight) = per serving cost
☆ Per plate cost added to garnish/decoration cost = total per plate cost

# = lb

Baking Theory Notes: Mixing Geekdom 2

Popular Dough Styles Methods of mixing dough, in bakery settings. If you analyze your home recipes procedure, you may notice most of your home bread or pastry recipes might mirror:" sponge & dough" or " straight dough" methods.



*Sponge & Dough Method


Very widely made.

--->Basic Formulation / Procedure:
  1. Mix half of the flour, yeast , malt , water @ <72°f> = sponge.
  2. Let it rise 3½ hours --- shake it, if it is done it will drop away from the sides.
  3. Remove sponge from your container, add to mixer with remaining flour, salt etc.
  4. Mix until gluten is developed.
  5. Bake
Advantages of Sponge & Dough method :
  • Better Flavor
  • Flexible --- In sponge stage you can leave sitting on the bench.
  • Better (tighter) crumb
{ This equals to ( 2) mix s and (2 ) fermentations {one in bowl , one in oven}

*Straight Dough Method
  1. 1 mix
  2. 1 fermentation
Advantages of Straight Dough Method:
  • Faster
  • Uses less electricity
  • Easier on equipment
  • Less Labor
*No-time Straight Dough Method
No fermentation. Additives cause "rise" activating Enzymes that normally developed during fermentation.
Basic Formulation / Procedure:

  1. Mix ingredients. Warm up the dough (i.e via mixing friction)
  2. Add more yeast
  3. Add Fructose (yeast can eat this faster)
  4. No Rounding --- Scale & put into pans to bake
Disadvantages of No-time Straight Dough Method:
  • Flavor IS compromised (from lack of fermentation)
  • Bad shelf life (unless you add additives)
  • No flexibility --- from mixer to oven (reminds me of "from zero to sixty")

Baking Theory Notes: Fermentation Chemistry 4

Fermentation

Remember: Fermentation starts when the mixer stops!


Control Fermentation through:

  1. Temperature
  2. Time
What happens during the fermentation process?
  • Gas is produced --> Carbon Dioxide {When Dough is mixed gas is caught by the gluten and the gas rises}
  • (water & flour cause enzyme activation)
  • Gluten is modified --> Dough becomes balanced so dough is workable : Elasticity --> Extendability
  • Flavor is developed (Acidity)
  • Alcohol is developed ("Alcoholic fermentation")
*To test the "alcoholic fermentation" theory ---> when you are ready to mix your formula, open a starter, either one retarded or left on the bench (Ciabatta or Croissant are especially potent!), lean in --- (as a former instructor would explain: "you rip back- because alcohol has hit your brain", he had such a big grin when he said this ) I am telling you --- it'll knock your socks off. The more "bake-tarded" (my own baker slang) you become, the more you anticipate smelling those starters! Ha HA!



Enzymes:

fermentation chemistry simplified
click here to see a bigger sized diagram of the chemical changes of fermentation.

Definition:
Biochemical Catylist: an organic substance formed by living cells (yeast), is able to cause changes in other substances {i.e bacteria, fungus or both } without changing it's self .

yeast cell budding



Diastatic = has enzymes
Non-diastatic = enzymes have been killed

Diastic Enzymes:

---> Supplied by flour / or Malt (sugar)
  1. Alpha-Amalase works on Amylose ---> Converted to Dextrin (sugar)
  2. Beta-Amalase works on Amylopectin ---> Converted to Maltose (sugar)
*These diastic enzymes are important because they work on STARCH.
---> Wheat is 70% starch (bran is protein)

Starch:

--->Amylose --->
--->Amylopectin--->

Diastatic Enzymes from flour (from milling) work on the damaged starch (i.e gelatinized (from heat / baking) and convert it to sugar (2% of starches) .

End result is mostly Maltose. Yeast cannot metabolize maltose.

  1. Maltase (enzyme) ---> converts to Fructose, Dextrose / Glucose)
  2. Sucrose [beet or cane] (granulated sugar) ---> Converts into Glucose
  3. Invertase (enzyme from yeast) ---> converts Glucose into Sucrose

Yeast takes maltose (enzyme) and converts it into Fructose, Dextrose / Glucose {allows yeast to eat it).

These processes take place if:
  1. Optimal Temperature
  2. Right moisture Content
  3. Allowed Optimal time
Zymase (yeast) ---> Reacts with simple sugars and injects CO2 into the dough causing it to rise. Produces alcohol.

Simple Sugars:
  1. Fructose = CO2
  2. Glucose = CO2
  3. Dextrose = CO2
Proteolytic Enzymes
  1. All from flour
  2. Can be found with Diastatic Enzymes
---> Protease ---> Converts protein ---> Modifies the gluten so dough is workable (softens and makes extendable)

*Over mixing dough will break dough down into "slime". I've seen this happen, it ain't pretty. Kinda resembles the stay puff marshmallow man (as the ghostbusters cross streams)
when he is obliterated --- a bumpy, jiggly white mass. yuck.

Baking Theory Notes : The Yeaasty Boyz 1

I liken Yeast to the popular and oh-so-old skool group ,The Beastie Boys. Both groups - whether rockin' the mike or the mixer, if given the best environment, will rock hard...and go on and on and on, improving on flavor. They both are fueled on additives and are a product of alcohol, whether that means straight drunk or chemically.....they get ill.


Beastie Boys by LaMoe79

YEAST

Purpose: Leavening of doughs
Optimum Temp: (to warm 33-40°F) (♥ prefer. 33-38
°F) as temp. deteriorates over time.

When Yeast is activated: 45
°F

Thermal Death of Yeast: 140
°F
Types:

----> Compressed Yeast
  • 73% moisture
  • Needs to be as fresh as possible for use.
  • Refrigerated
  • Has not been processed as much as dry yeast.
  • Fresh yeast is best for products to be frozen
Conversion Rate {If formula calls for Active Dry Yeast, you will need 2½ X [the amount in formula] = amount of compressed yeast needed}
----> Active Dry Yeast
  • Can be stored for 1 month.
  • Has to be reconstituted in 4x it's weight.
  • Not used as frequently in bakeries, as in restaurant kitchens.
Conversion Rate {To substitute Compressed Yeast in a formula : multiply 2½ X [the amount of Active Dry Yeast] = amount of Compressed Yeast needed }

----> Instant Dry Yeast

  • Shelf life of 1 year
Conversion Rate {To substitute Instant Dry Yeast in a formula calling for compressed: multiply 3 X [the amount of Compressed Yeast ] = amount of Instant Dry Yeast needed }

Baking Notes : On Proof Boxes, Hints for newbie Baker 2

Proof boxes aren't necessary for a bakery, especially a small one, over time you learn to "feel" the doughs textures --- from mixer to bench, from bench to board, from board to oven. This is the unspoken seventh sense those "one" with the dough possess.
Like everything, baking is akin to Star Wars. "Just as the path of a Jedi is often difficult, filled with conflict and pain". As is the path of the newbie baker.

"To become a Jedi requires the deepest commitment and most serious mind. It is not a venture to be undertaken lightly. As such, Jedi instruction is rigidly structured and codified to enforce discipline and hinder transgression... A Jedi who fails in his training can be a very serious threat. The dark side of the Force beckons to the impatient, and students in the past have been lured to its call with devastating consequences."


In The Empire Strikes back, Young Luke Sky walker, motivated by the spirit of Jedi
Obi-Wan Kenobi , ventures out into Dagobah swamp ( of the Dagobah Systems) inhabited by Yoda , Jedi Master. While in Dagobah swamp, Luke Skywalker learns the "ways of the Force" from Yoda, and to hone his Jedi abilities.

And just as Luke Skywalker before you --- Newbie Baker, You too will learn to harness your "baking" abilities.


Every baker --- whether novice or master, all venture into the unknown realm of chemical activity, the eclectic rhythms guiding hands and thoughts into a carbohydrate fueled symphony. With each turn of dough, each shaping of a round, your mind will develop a map of sensory memories. If you are new to this baking realm, don't just make mental notes, make visual and textural ones as well . If you follow this simple plan, the "baking" force will become strong within you.


A.K.A "Proofer" , "steam box" ,"Steam Cell"

Proof Box Advantages:

  • Control temp. & humidity
  • Proofs at same humidity & temp. , regardless of weather.

Capacity

  • If oven is full at all times, you have gained proper efficiency.
Larger proof box vs. small oven:
  • [2 : 1] or [3 : 1] ratio {2-3 pans proof to every 1 pan bake in oven}
  • 1 hr proof : 20 min of baking time = more profit / cost effective
Why Invest in a Hydrometer:
  • Measures exact humidity in air
Proof boxes are notorious for being unbalanced in humidity.


TYPES:

Cabinet Proofer
Characteristics to Look For:

  • Corrugated Steel ledges to hold sheet pans:
If you can't purchase a proofer with wire supports. Solid steel doesn't work as well, when the ledge makes contact with the sheet pan, it will block steam which rises from the bottom of the Cabinet Proofer (the bottom is where the controls are housed). This will affect your proof.

  • Walk-in Cabinet Proofer
These proofers have better ventilation and are much sturdier.

  • Wire holders/supports for sheet pans
Supports (i.e solid steel / corrugated) tend to break off. Or need to be readjusted. Purchasing wire supports will cut down repeated maintenance.


Rack Proofer
Advantages:

  • Best Performance
  • All sizes, to meet space requirements/ production yields
  • Good for production

Retarder Proofer
Advantages:

  • Has variable temps (frozen to thaw --> to proof) timer.
Shelf Type Proofer
Features:

  • Removable shelves
  • Frozen bake-off operations (Main use)
  • Proofer is stacked on top of oven
Disadvantage:

  • Not ergonomically designed

Baking theory Notes: Chemical leavening; Dough strengthener; Crumb softeners 0

Chemical leavening

  1. Reaction of Sodium bicarbonate (baking Soda) & An Acid
  2. [Acid + Salt + Water = Carbon dioxide gas]
  3. Baking Powder is this Formula plus a filler to retard reaction.
  1. Double Acting Baking Powder is 2 acids

- Substances that react like acids:

  1. [buttermilk]
  2. [chocolate] { kill reaction (rise) made by baking soda, that is why these are commonly used in cookie formulas}
  3. [lemon/citrus juice] { kill reaction (rise) made by baking soda, that is why these are commonly used in cookie formulas}

Dough strengthener

  1. Eggs
  2. Ascorbic Acid (vitamin C) [only additive allowed in European Production of Baguettes/French bread]
  3. Potassium Bromate ---> {outlawed in most countries , NOT the U.S} carcinogenic = causes cancer
Basic formula for bread {100% flour + 60% water + 2% salt + 2% yeast)

Crumb Softeners {click here for more info}

Function:
Surfactants, through complexly with flour protein(gluten) break the surface tension between non mixable substances.

  1. Give longer shelf life in bread [yeast raised products]
  2. emulsifier & surfactants retard the Staling.

Two ways of Staling
  1. starch molecules change & become rigid
  2. loose moisture in product becomes dry.

Baking Theory: Dough Preparation & Fermentation 4

Steps as a Successful Baker :

- Have Balanced Formulas

--- A collection of formulas that work
--- Formulas you have tried out in your bakery & changed to suit your needs
--- Be a Control Freak
--- Have Consistency every time!
--- Know Functions of Ingredients in your formulas, so as to predict the outcome.

-Know Proper Mixing

[1st speed]

--- Remember your Goal is Consistency
--- know that To Control consistency, hold back water.
--- Know NEVER to control mix with flour!

--> Gluten Development

[
2nd speed]

--- know Proper gluten development VERY important, if dough is mixed too long gluten will separate.


*know your 3 main types of mix:

[Short ] {uneven gluten, tears window}

Uneven Window


[Intensive] { not quite a window, small tears}

[Improved] {fully developed window, feels like skin}

Fully Developed Window




{To check for the development of your dough :
  1. Stop mixer, tug on a piece of dough {always from the bottom, due to more consistent mix} You will feel an elastic feel the longer you mix.
  2. Take out the piece of dough. Start pulling from the bottom of your dough piece Until it is very thin in the middle & forms a window. Let the dough get pliable in your hands -- do not force the stretch.
  3. Hold on sides, & hold up the "window" to the light. You will see the gluten will form "strands" criss-crossing in your dough like a crude mesh , as it starts to develop.
  4. Gently touch with a finger - if it is taught, the dough is ready for the next step}


- Know Fermentation

{note :
artisan bread doughs have longer fermentation}

--- Longer fermentation means shorter mixing.
--- Gluten is modified {Acidity = Flavor}

[ Dough Temperature] [completion of mixing]
{ Best environment for fermentation is 50°F & 80% humidity. Dough doesn't ferment well under 40° F}

---78°F - 84°F [can be as low as 74°F]
---If you lower temp. fermentation slows
---If temp is raised fermentation speeds up.
---Remember cool doughs make for the best fermentation.

[ the process of Fermentation ] [alcoholic fermentation starts]

---Remember fermentation starts as soon as mixer stops.
---This is the MOST important part of bread making
---Gluten is biochemically modified
---improved stretchability
---improved elasticity
---Carbon dioxide gas is produced
---Acidity

-When Scaling out dough

{an efficient experienced baker can handle 8 gal at a time}

---You should never scale out more dough than you can handle in 15-20 minutes. Or dough will ferment further while sitting & product will be nonuniform[larger] .

-Tips for Rounding & Shaping

{ Additional Gluten development = mix + folding (bench work) }

---Pre-shaping
---Cover after pre-shape or "crust" will develop

- Intermediate Proof or Bench Time

---The time when dough has been rounded & now resting under plastic.

- Molding & Shaping

---Flatten dough rounds out to expel gas
---Shape into final loaf

- Panning

Mise en place :

---boards
---Strap pans
---Serrated sheet pans

{ seams must be bottom down to prevent splitting of loaf while baking}

-Proofing

---Put into a Proof Box, steamer.
---Almost the last fermentation.
---95°F -98°F , 80% humidity
---Proof according to product
---don't let dry out
---Touch

{Finger imprint test

  1. Lightly tap the top of a loaf in the proofer-- Finger should stay imprinted in dough if proofed enough
  2. If proofed too long/not enough you can't repair dough.
  3. Over proofed dough can be put into a hotter oven to try & kill yeast immediately. To save product}

Baking Theory Notes: Sweeteners 0

Sweeteners:

---Sugar in bread dough is an additive

  1. [Basic bread formula: water, flour, salt]

Functions of sweeteners:

+Moisture
  1. Sweeteners are Hydroscopic --> [bind moisture]
+Flavor
+Color

without sweeteners you have Pale bread / pastry
  1. can be the result of adding no sugar
  2. or yeast dissolved [was eaten] during the intial mixing.
+Tenderizer
  1. in cakes and cookies
+ Stabilizer
  1. In cakes
+ Fermentation Control

  1. A dough which makes it's own fermentation using sugar, makes a richer , complex flavor.
  2. Dough high in sugar takes a long time to ferment
  3. sugar sucks moisture out of yeast.

Types of Sweeteners:

+Granulated
  1. beets
  2. Cain
+Powdered
  1. Used for icings & fillings
  2. Look On the back of the package / recipe, The higher the amount of eggs they list to add, the finer the sugar you should use.
+Hi-Fructose Corn Syrup
  1. Cheaper
  2. more efficient
  3. Fructose is a simple sugar, easily broken down in the body.

Baking theory Notes: Other Flours 0

Other Flours used in production bakery:


+Brown Rice

  1. when milled produces Rice Flour
  2. Heavy, dark flour
  3. Very rich flavor
  4. Gives heavy character to bread or whatever it is added to.


+Soy Flour


  1. finely ground soy beans
  2. added to other flours
  3. Enriched more than other flours
  4. Low fat content
Potato flour
©1996-2003 Lori Alden, As seen on The Cook's Thesaurus.Click picture. 


+Potato


  1. Flavor goes well with wheat
  2. Moistens bread





+Vital Wheat Gluten



  1. Manufactures for supplementing in gluten, for strength.
  2. Starches are stripped from the sponge/starter & marketed as "pure gluten".

Baking Theory notes : Rye 0

Rye:

Rye Upclose and Personal  by P1r





Parts of The Rye kernel:

  1. Germ = Very core, inner center, where sprout develops.
  2. Bran = outer Layer wrapped around the germ.
  3. Endosperm = inner middle of the kernel.
About Rye :
  1. Rye has no Gluten
  2. Rye flour used on it's own makes for a very dense bread. -- an example of this is Pumpernickel.
  3. Usually mixed with a hard four to produce better bread.

Rye Flour Types:

  1. "Light" rye flour -- made from inner most endosperm
  2. "Medium" rye flour --- made from whole endosperm
  3. "Dark" rye flour --- made from Outer endosperm
  4. Rye "Meal" -- made from whole kernel


06 February 2005

Baking Bread: Trouble shooting 0

holes in bread


Large holes in bread :
  1. Dough was over kneaded
  2. Dough was proofed too long*

*For Breads such as French or certain free form loafs , this can be an advantage.

Doughy or Small, hard lumps:

  1. Original dough was not mixed enough*

* hold back flour so dough can thoroughly mixed, work in additional dough as you knead

Bread "Mushroomed" & there is a deep indentation around the bottom:

  1. The entire loaf has broken away from the bottom crust
  2. You tried packing too much dough into too small of a pan

++If a free form loaf:

  1. Oven was too hot causing the bottom to cook too quickly
  2. As the loaf rose it broke away and mushroomed [uneven & Denser]

Free form loaf "spread" too much as it proofed

  1. Dough was too soft**

* free form loaves must be firm when shaped. Add extra flour as you knead.

When sliced - top crust "separates" from the rest

  1. Loaf was not properly formed
  2. Heat caused instant aeration when loaf was put in oven.*

* not serious, alter your methods

05 February 2005

Baking Theory: Notes on Bread Baking 2

Baking:

  1. Oven Spring {created in 5-8 minutes in oven, accelerated fermentation process}
- Fermentation process

  1. Once dough reaches 140°F {yeast dies}
  2. Once dough reaches 165°F-175°F {gluten coagulates}
  3. Considered Par-baked --> ["brown n' serve products"] can be pulled from oven.
  4. Because products are Not caramelized--> causes quicker staling.

- Caramelization

  1. Browning
  2. Internal temperature of fully baked bread = 210°F
  3. bread is sterile

Potato Bread shown here is rotated for even browning. Then baked until...

..It has caramelized. Potato Bread ready to cool.


Rule of thumb for Oven temps :
  • LEAN products -
  1. The lower in fat, sugar , eggs {examples are Baguette or Italian Bread};
  2. also if Smaller units

  • RICHER products

  1. The Warmer, hotter oven
  2. The higher in fat, sugar , eggs { i.e Danish or Croissant}
  3. also if larger units
  4. The cooler the oven
- Cooling, Slicing & Packaging

-{Once you have mold in an area - spores will spread. Use vinegar to kill both mold & spores}

DO NOT put in plastic bag & close before product is cool --> Mold will develope!

  1. via Condensation
When to package:
  1. 95°F - 100°F is optimal temp --> {cool}
  2. Use back of hand to test for cool to touch















04 February 2005

Baking theory notes : Salt & Yeast 0

Salt

Functions of salt:

- thickener
- Tightens up gluten.

- Retards Yeast
- Balances out/controls fermentation by killing yeast.

- Intensifies Flavor
- Brings out the flavors of other ingredients.



Yeast

Types of yeast:

Compressed Yeast

- Comes in 1lb. cubes

-73% moisture

- Alive

- Must be stored at 33° F - 45° F

Draw backs:

-- [less effective] Yeast easily becomes active & deteriorates quickly.
-- Average shelf life is 10 days.

Tips:
[From a cost standpoint this yeast is less effective due to the yeast easily becoming active & then deteriorating. If using in a scratch retail environment you need to have a inventory plan. The most cost effective plan entails purchasing enough Compressed yeast to last 1 week. By ordering weekly you eliminate both unnecessary inventory loss & cost.]


Bulk Yeast

- comes in 10lb bag lined in plastic.

Active Dry Yeast

- cooks mostly use this [not professional bakers as much, we prefer compressed]

-7.5 - 9% moisture content

- Shelf life 1-2 wks

Draw Backs :

--the yeast takes too long to develop
--not cost effective
--bakers are under time constraints.

Granular Yeast

-free flowing

-resists compacting

- reduces proof time.


Instant Dry Yeast

- Shelf life is 1 year

-vacuum packed

- high availability [even in grocery stores]

- first marketed during the 1980's in France

Draw Backs:

- costs more

Tips:

[If using a formula that calls for Compressed Yeast & you would like to supplement Instant Dry Yeast in it's place, use 1 ⁄ 3 of the amount yeast specified in the formula. ]

Baking Theory Notes: Fats 0

Fats:


Clarified Butter By Chiot's Run



Fat added to yeast dough lubricates



+Lard

  1. Hog fat or other animal fat.

+Molecular Modified Lard

  1. deodorized
  2. consistency is changed
  3. High Plasticity range
  4. Good for pastry

+Standard Shortening

  1. Original Blend
  2. hard oils + soft fats
  3. Animal fats + Vegetable Fats
  4. Not hydrogenated

+Hydrogenated Shortening
[end result is Trans fat = solid fats higher in fatty acid.]
  1. Chemically altered
  2. saturated with hydrogen
  3. Hydrogen atoms attach to fat molecules, become stable [firm]
  4. Made up of vegetable oils [ example ---palm, soybeans, rabeseed, canola]
  5. vegetable oil alone is harder to use
  6. harder to store, turns rancid quickly.
  7. final product = better storage
  8. Easier to build plasticity


+Fluid Shortening

  1. Made from Tropical oils or mutton fat.
  2. Combo of oil + hard fats + emulsifiers
  3. Sold in a tin can.

+Emulsified Shortening Added to bread it aided in the shelf life, inhibits the staling process.


Mono- & Di-glycerides = Surfactant
  • A Surfactant enables you to mix un-mixable compounds
  • A Surfactant lowers the surface tension of whatever solvent you add it to.
  • Surfactant, if used , can cause you to add a higher percentage of sugar than the formula calls for. You don't want that!
High Ratio Shortening
  • Used in Cake batter, which is an Emulsion



+ High Ratio Shortening

  1. mostly used in cakes


+Margarine

  1. 80% fat + emulsifiers + color + water

+Baker's Margarine*
*Must be right percentage of fat content, or fat will not melt in mouth! Pastry texture suffers.
  1. Higher melting point
  2. Colorless
  3. High Plasticity

+Roll-in Margarine*
*Must be right percentage of fat content, or fat will not melt in mouth! Pastry texture suffers.
  1. used for pastry [puff, Danish]



+Butter
** With Use of butter ---charge per pastry increases, Labor increases
  1. 80 - 81% Butter Fat
  2. 14% water
  3. additives:
+ milk solids
+ minerals

  • Low melting point
  • Gives lot's of Flavor
  • Low Plasticity

Baking Theory notes: Wheat/Flour 1


" Flour is to wheat , as Wine is to Grapes "


What is the most important food in the world?
* Rice

our text book was wrong - listing wheat as number one. In reality wheat is 2nd in the world.


Wheat:

Parts of a wheat kernel :
Cross Section of Wheat


* The Germ Where sprout is formed, supports seed fat, vitamins & minerals.


* The coat or Husk The outermost covering of the kernel. "Chaff"



* Endosperm The inner most center of the kernel.

* Bran The layer covering the Germ.





Milling:

* Separates the Germ & Bran
---bran contains the "fat", which is taken out to give flour a better shelf life. Otherwise it would go rancid.
* Reduces the chance of Endosperm entering into the flour. For Less expensive production & marketing of flour.

---Whiter more exspensive flour comes from the Endosperm.

---Quality of wheat effects the quality of Flour.



[types of milled Flours]:



+Patent = Made with the endosperm
--- remnants from milling patent flour are made into Clear Flour.
+Straight = Made with the whole middle part of the wheat kernel

+Whole Wheat Flour = Made from the Whole kernel.
---Due to fat content in bran, easily spoils/ goes rancid.





What effects wheat?
* Climate
* Soil


---Montana produces a large amount of Hard wheat due to the colder, drier conditions

--- Where Oregon produces Soft wheat due to mild, wetter conditions.



Specific Types of Wheat:



+ Hard Red Spring
---Sowed in the spring
---Areas with tough climates
---harvested in the fall



+ Hard Red Winter

---Sowed in the Fall
---Harvested in spring


+ Soft


What kinds of wheat flours are there?

+ Hard Wheat
---High in protein = more Gluten
---Used for bread [produces a chewier inside, crusty outside]

---Made from Spring Red Wheat
---grown in the West, mid-west & Southwest...notably Deaf Smith Country, Texas
---known for mineral content
---Make firm, elastic breads

*England named it Strong Flour

[ Hard Flours ]:

+ High Gluten [11 - 13 % protein]
+Clear [13 - 15% protein]
---Used in producing Bagels, Rye Bread
+Bread flour


+ Soft
---Lower in protein = less Gluten
---Used for pastry, cookies [produces tenderness, melt-in-your-mouth texture]
---from mostly the Mid-west
---An asset in pastry due to "smoothness"



[ Soft Flours]:
+ Cake Flour
+ Pastry Flour [used in pie crust, cookies etc.]



Why Use wheat?

* Protein of wheat
--- Gluten
which consists of :
---Glutenin

---Gliudin

---Gluten holds back gas causing bread dough to proof [rise]
---Gives bread structure
