|
Milk contains an enzyme that does what in yeast breads?
|
Interferes with gluten development, so milk should be scalded by heating to a simmer to kill the enzyme and then cooled before use.
|
|
What are dough conditioners?
|
They are a mix of ingredients to strengthen gluten. Their selection depends on the hardness of the water and the pH level; also the selection of flour.
|
|
What can inhibit gluten development?

Solid pieces added to bread dough such as:
herbs nuts olives grated cheese |
|
What does bran inhibit?
|
Gluten development by preventing strands from sticking together.
|
|
Why is salt important in yeast doughs?
|
1. helps regulate yeast fermentation
2. strengthens gluten and makes it more elastic 3. yeast doughs without salt will tear and are harder to handle. |
|
Why should tender products such as pie dough be made with ice water?

rice syrup is . . .
|
less refined, so it is marketed as a sweetener to the health food industry
|
|
high-intensity sweeteners are also called . . .
|
nonnutritive or artificial; they may be 200 times more sweet, but they are unsuitable for baking
|
|
what is the glycemic response?
|
how fast sugars break down during digestion and provide energy to the body
|
|
what are the four most common high-intensity sweeteners?
|
Sweet n Low - saccharin
Equal, NutraSweet - aspartame Sunett - acesulfame potassium Splenda - sucralose neotame - not yet in market |
|
functions of sweeteners are:
|
sweeten
tenderize improve shelf life retain moistness contribute brown color |
|
Give order of sweeteners from sweetest to least sweetest . . .
|
fructose, sucrose, glucose, maltose, lactose
|
|
How does sugar tenderize?
|
By interfering with gluten formation, protein coagulation and starch gelatinization
|
|
What happens if you have too much sugar in your formula?
|
The structure can't form, the batter or dough won't rise, and it will collapse as it cools.
|
|
Why are products with dairy susceptible to Maillard reaction?
|
they contain milk proteins and lactose, which brown quickly.
|
|
Which browns faster, monosaccharides or disaccharides?
|
Monosaccharides. That's why invert syrup with fructose and glucose monosaccharides brown faster than granulated sugar (sucrose).
|
|
give the order of the rate of browning from fastest to slowest . . .
|
fructose, glucose, lactose, sucrose, maltose, isomalt
|
|
The browning of sugar increases in the presence of what ingredient?
|
salt - and also minerals like copper, iron and lead
|
|
acids and alkalis affect browning how?
|
by affecting the pH level.
|
|
A small amount of baking soda increases pH, which does what?
|
helps browning
|
|
buttermilk and cream of tartar lower pH, which does what?
|
slows browning
|
|
How does sugar assist leavening?
|
It has air between the crystals.
Only dry sugars help with leavening. |
|
Why doesn't syrup assist in leavening?
|
it has no air
|
|
What does sugar provide?
|
bulk and substance in fondant, and helps define size and shape of products
|
|
Sugar helps stabilize what?
|
Whipped egg foams and egg whites
|
|
Sugar provides what for fermentation?
|
food for yeast
|
|
Name more sugar functions . . .
|
adding flavor
reducing iciness in frozen desserts interfering with ice crystal formation |
|
heated sugar molecules form
|
polymers that absorb light
|
|
what causes cracked, crisp crusts to form in cookies, brownies and pound cakes?
|
moisture evaporation
sugar crystallization |
|
syrups high in moisture such as maple syrup and simple syrup must be . . .
|
refrigerated to prevent mold growth
|
|
syrups high in glucose should not be refrigerated, why?
|
because they may form crystals
|
|
all sweeteners should be stored covered to prevent . . .
|
pickup of odors and absorption or loss of moisture, especially powdered sugar and brown sugar
|
|
If powdered sugar has clumped, how can you fix it?
|
use a sieve
|
|
If brown sugar has clumped, how can you fix it?
|
gently heat in oven or microwave before sieving
|
|
what is the shelf life of covered, dry sugars?
|
unlimited
|
|
most syrups contain what percentages?
|
80% sugar to 20% water
|
|
What is the formula if you want to substitute syrup for granulated sugar?
|
Divide weight of sugar by .80 to determine weight of syrup, and reduce the water by the difference between the two. Example: for 1 pounds, 16 ounces times .80 = 20 ounces for the syrup, and reduce the water by 4, the difference between 20 and 16.
|
|
What is the formula if you want to substitute sugar for syrup?
|
multiply the weight of syrup by .80 to get weight of sugar to use. Increase liquid by difference between the two.
