*Fats and Proteins

Page 2: Fats and Proteins

*Cooking with fats

*Smoking point?*Do not use olive oil to deep-fry*Adds flavor, tenderness, crispness*Prevents sticking

*Keep tightly covered; picks up other flavors easily*Store properly to prevent becoming rancid

Page 3: Fats and Proteins

*Saturated Fat

*Solid fat at room temp*Mainly from animal foods

Page 4: Fats and Proteins

*Saturated Fat

1. Hold in body heat2. Shock absorber3. Carries vitamins A,D,E,K4. Formation of body cells5. 10% of daily calories

Page 6: Fats and Proteins

*Cholesterol

1. White, waxy fat made by the body and part of every cell

2. Only in ANIMAL foods3. Body does not need extra because body makes

enough4. Extra causes clogged arteries and high blood

pressure5. Needed to make sex hormones and bile acids

Page 7: Fats and Proteins

*Complete Protein

*Contains ALL amino acids needed by the body*Beef, bison, pork, veal, mutton, lamb, fish, poultry,

variety meats liver, kidney, heart, tongue, sweetbreads(thymus gland), tripe (stomach), brains, chitterlings (cleaned intestines)

Page 8: Fats and Proteins

*Complete Protein Functions

1. Build and repair cells2. Make enzymes, hormones, antibodies3. Help transport iron and oxygen4. Provide energy (12% of daily calories)

Page 9: Fats and Proteins

*Incomplete Protein

*Contains some of the amino acids needed by the body; needs to be eaten in combinations to make a complete protein*Grains/dairy or grains/legumes or legumes/dairy

Page 10: Fats and Proteins

*Cooking with Proteins

*Destroys harmful bacteria*Improves flavor*Makes easier to digest

Page 11: Fats and Proteins

*Tenderizing Techniques

*Collagen broken down during cooking; can be aided with chemicals*Meat tenderizers, marinades,

*Elastin not broken down during cooking but can be mechanically*Pounding, grinding, cubing, etc

*Overcooking and cooking at too high a temperature causes toughness

Page 12: Fats and Proteins

*Choosing meat cuts

*Look for marbling – streaks of fat thru meat*By bone (pg 239) - *Tender – t-bone, rib, hip (pin, wedge, flat)*Not as tender – round, neck (blade)

*By name (pg 236) – *Parts of animal not exercised (across back) are

the most tender – loin, rib*Exercised parts need some kind of tenderizing –

some more than others – arm, chuck, shank, flank

Page 13: Fats and Proteins

*Meat Labelstype of meat, wholesale, retail,

price/lb, total weight, total price, sell by date,

Page 14: Fats and Proteins

*Dry cooking methodsfor tender cuts

*Roasting – large tender cuts; cook fat side up; allow to sit 10-15 min before cutting*Broiling/grilling – direct flame; thin cuts

like steaks/chops; season after browned to seal in juices*Panbroiling – like broiling but in skillet on

stovetop; pour off fat that accumulates*panfrying – in skillet w/o pouring off

accumulated fats; stir-frying

Page 15: Fats and Proteins

*Moist cookingmethods

for less-tender cuts

*Use less tender cuts of meat*Braising – brown outside the cook in small

amount of liquid with tightly covered lid; low heat*Stewing – meat covered in simmering

liquid
