BASIC INGREDIENTSINGREDIENT FUNCTION• Flour Body/Structure• Yeast Leavening (rise)• Liquid Binder, moistens• Salt Flavor, controls yeast• Sugar Flavor, feeds yeast• Fat Tenderizes, aids
browning• Eggs Structure, flavor, richness

Characteristics of Yeast• Must have warmth, moisture, food
• Is a living organism
• Will die if subjected to too much heat

Food Science Principles of Yeast Breads
• Fermentation– Yeast breaks down into sugar and energy– Longer, slower fermentation = better flavor–Change the rate of fermentation by:• Temp of dough• Amount of salt• Amount of sugar• Amount of yeast

Food Science Principles Cont.
• Kneading–Distributes yeast throughout dough–Develops gluten (proteins in flour)–Too much kneading will cause the
dough to lose flavor after it is baked–The dough has been kneaded enough
when it stretches like bubblegum

Food Science Principles Cont.
• Proofing– The ‘rising’ process – the dough ‘puffs up’– Can speed up process by use of a ‘proof box’
• Shaping– Using the hands to mold the dough into the shape
of loaf or roll that one desires

Food Science Principles Cont.
• Baking/Oven Spring– Use correct temperature– Choose correct size pans– Prepare the pans– Bake the product– Oven Spring – one last jump inn size in the oven
before the yeast is killed– Remove baked product from pans, place on
cooling rack

Proof Box at Home• Place a shallow pan of hot water on the lowest shelf in
the oven (proof box).• Turn on the (proof box) to the lowest temperature.• Place product in the oven (proof box) and allow to rise
to the proper height.• Remove product from oven (proof box).• Remove the water from the oven (proof box).• Turn temperature to baking temperature, allow to rise
to that temperature. • Place product back into oven to bake.
