Heat Transfer
Heat energy traveling through space or air.
What is radiative heat transfer?
A loaf of bread begins to stale at this point.
What is removal from the oven?
I require moisture to gelatinize.
What is starch?
3 forms of leavening.
What are chemical, biological, and physical?
The reaction of baking soda with an acid.
What is chemical leavening / reaction?
Heat energy traveling from one molecule to another.
What is conductive heat transfer?
The temperature in which yeast is killed.
What is 140 degrees F.
I melt early in the baking process causing spread in cookies as well as tenderizing baked goods.
What are fats?
This happens to gasses trapped in a baking item.
What is expansion?
An example of a biological leavener.
What is yeast?
A "stirring" type of molecular movement that aids heat transfer.
What is convection heat transfer?
This process is why bakers must scale the dough for a one pound loaf for retail sale a bit more than one pound.
What is evaporation?
Two common tenderizers in baked goods.
What are sugars and fats. Also leaveners or syrups.
An example of a physical leavener.
What happens to - gasses as they expand / water as it turns to steam?
The main gas created when baking powder is exposed to moisture and heat.
What is CO2 / carbon dioxide?
A cooking process where heat is generated through the use of magnets.
What is induction cooking?
A term used to describe the unraveling of protein.
What is denaturation?
Two items help set the structure of bread. And I am the softer of the two.
What is starch?
During this part of the "baking process" gasses contract causing many baked goods to shrink back in size.
What is cooling?
This LIQUID is produced by fermentation and assists in leavening.
What is alcohol?
Toasters and heat lamps display this type of heat transfer.
What is radiative or radiation cooking.
A term used to describe proteins changing when exposed to heat.
What is coagulation?
A term used to describe the changes to starch as it is heated.
What is gelatinization?
These two common bakery ingredients can be mixed to make single acting baking powder.
What are cream of tartar and baking soda?
The 3 most important leavening gasses.
What is air, CO2, and steam?
