Dry Heat
Best for delicate cuts of meat
Examples of dry heat
BBQ, grilling, frying, roasting, stirfry, baking, broiling
what is Moist heat
Best for tougher cuts of meat, method will break down meat and kill bacteria at the same time.
Examples of moist heat
braising, simmering, boiling, stewing, steaming, poaching

Braising: brown the meat and put in small amount of water in low heat for long time
Stewing: submerge in water, cook in shorter time in chunks.
Additives
FDA controls.

Name: Monoglycerides, soy lecithin, egg yolk,
Fat free dressing you would use which emulsifer
Soy lecithin- prevents seperation
Regular dressing you would use which emulsifer
egg yolk
Stabilizers, thickeners, binders, texturizers
what
examples
name
What: produce same texture, improve mouth feel
Ex: Dairy products, cake, , jams
Name: Gelatin, pectin, carrageenan, xanthan gum, whey

grapes/wine
walnuts/fish
tomatoes, watermelon, apricots
have resveratrol: lowers platelet aggregation
has omega 3, lowers TG levels
has lycopene, may reduce prostate cancer risk
Phytochemicals
compounds produced by plants, for humans provide prevent/ treat chronic disease like cancer, detoxify, protect LDL cholesterol
Indols
Found in Cruciferous veggies- broccoli, cauliflower
can reduce risk of breast cancer, detoxify cancer causing agents
Isoflavones
Found in soybeans
Decrease elevated cholesterol levels
Gelatinization
when heated starch swells
Example: sauces
retrogradatoon
when starch recrystallizes becoming solid
Retro=old
old= stale bread
Maillard
Non-enzymatic
Maillard likes to cook until bread is brown
Enzymatic
Fruits, veggies brown naturally
an open apple, an open avocado.
Adding bran decreases the volume of end products how do you resolve
add two F’s
flour and fluid to compensate
An example of a fermented product
yogurt
