Excellent sources of complete protein

Meat & Poultry

Iron & Zinc

Fish

Omega-3 essential fatty acids

Nutrition

Cholesterol

All animal muscle contains about the same amount of cholesterol per ounce

Fat

 content varies

Types of fat

Meat & Poultry

Invisible fat- within the chemical composition of the food

Visible fat

Marbling w/in the muscle tissue of the meat

Makeup of Meat & Poultry

Have very long, thin muscle cells

Thinnest in young animals

Thickest in older animals and those parts of the body that get a lot of exercise

The thicker- the tougher

Connective Tissue- protein material that surrounds cells

Collagen- thin, white or transparent; when cooked turns into a gelatin

Elastin- tough, yellowish; tenderizing methodspounding, cutting or grinding

Makeup of Fish

Very short fibers arranged in layersflakes when cooked

Separated by thin, fragile connective tissue

When heated- gelatin

Fish & Shellfish-----very tender

Types of Meat

Beef

Cattle, more than 1 year old

Bright red flesh

Veal

Calves, 1-3 months old

Mild flavor, light pink color, little fat

Lamb

Young sheep

Mild but unique flavor

Bright pink color w/ white brittle fat

Pork

Meat from hogs

Grayish pink color w/ white fat

Cuts of Meat

Wholesale cuts

 large cuts for marketing

Basically is the part of the animal the meat came from

Listed 2 nd on label

Types of Cuts

Retail Cuts

Smaller cuts (supermarket)

Specific to the meat you are buying

Listed 3 rd on label

Label

Bone Shapes

Wholesale cuts have distinctive bone shape

Nearly identical in all

4 types

Clues to the tenderness of the meat

Lean Cuts

Lean

Less than (based on 3.5 oz. serving)

10 grams of fat

4 grams of saturated fat

95 milligrams of cholesterol

Appearance

Less than ¼ in. fat around meat

Beef Roasts & Steaks: round, loin, sirloin, chuck arm

Pork Roasts & Chops: tenderloin, center loin, ham

Veal Cuts: all except ground veal

Lamb Roasts & Chops: leg, loin, fore shank

Ground Meat

Beef trimmings

Law- cannot contain more than 30% fat by weight

Different types sold- leaner ($$$)

You may ask to have meat ground up for you at the store (If not available)

Lamb, pork, veal

Inspection & Grading

USDA

Stamped w/ harmless vegetable dye

Meat

Graded according to:

Marbling (internal fat w/in the muscle tissues)

Age of animal

Texture and appearance of meat

Common grades of beef:

Prime

Well marbled, tender, flavorful, $$$

Choice

Most common, less marbling than prime but still tender

Select

Least amount of marbling, least expensive

Lamb & Veal

Same as beef w/ “good” replacing “select”

Pork

Not graded due to uniform quality

Storing Meat

Refrigeration/Freezer

Ground Meat-

 refrigerator 1-2 days

 freezer 3-4 months

Fresh Meat-

 refrigerator 3-4 days

Freezer 6-9 months (beef can be stored to

12 months)

Processed Meat

Processed for distinctive flavor

Types:

Ham, bacon, sausage, cold cuts

Curing

Placing the meat in a mixture of salt, sugar, sodium nitrate, potassium nitrate, ascorbic acid and water

Smoking

Liquid smoke for flavoring

Drying & Salting

Preserves meat

Combo

Bacon- cured and smoked

Chipped beef- dried, salted and smoked

Preparing Meat, Poultry, Fish &

Shellfish

Cooking

Color

Red to brown

Pink to white

Flavor

Heat creates chemical reactions w/ in the cut

Texture

Heated meat loses fat and moisture—shrinks

Muscle fibers get firmer

Connecting tissue becomes more tender

Moist Heat

Less tender cuts

Methods

Simmering

Stewing

Braising

Overcooking- mushy meat, loses flavor

Marinating Meat

Marinade-

 steeping in a liquid

Tenderizing

Adding flavor to meats

3 basic ingredients

Oil, an acid, seasonings

Using marinades

Fish- 30 minutes to an hour

Meat and poultry- 6-8 hours (30 min. for some flavor is good)

To cook:

Drain food from marinade

Make a separate batch to baste with

Cooking Meat

Thaw any frozen meat

Clean meat

Rinse w/ cold water & pat dry

Trimming the fat

Moist heat- remove skin from poultry

Dry heat- leave skin on while cooking to prevent drying out

Using a meat thermometerinsert into thickest part of meat, away from bones & fat

Fish- “10 minute rule”

(10 min. for every inch in thickness)

Doneness

Cooking Methods

Roasting or Baking

Broiling

Poaching

Microwave

Pan-fry

Stewing

Braising

Stir-frying

Poultry

Chicken

Chicken-

Light meat- leaner and milder flavor; breasts and wings

Dark Meat- more oxygen in this part of meat

(more myoglobin) which causes dark color; legs and thighs; higher in fat

Purchasing Chicken- whole, cut up, or in specific parts

“Fresh”- never been chilled below 26 F

“Hard Chilled”- chilled between 0 F and 26 F

“Frozen” or “Previously Frozen”- has been chilled to below 0F

Chicken

Broiler-fryer

Most tender & most common

Roaster

Larger & older than broiler-fryer

Yield more meat per pound

Stewing

Older, mature birds

Less tender----must use moist cooking methods

Rock Cornish game hens

Young, small, special breed

One bird= one serving (Mid-evil Times)

Capons

Desexed roosters under 10 months old

Tender & flavorful, best roasted

Turkey

Larger than chickens and have a stronger flavor

Roasting- most common cooking method

The different type of turkeys are categorized by size:

Beltsville or Fryer-roaster-

Smallest type of turkey

Average weight 5-9 lbs.

Least available type of turkey

Hen-

Female turkey

Average weight 8-16 lbs.

Tom-

Male

Up to 24 lbs.

Ducks & Geese

Ducks and Geese-

All dark meat

Flavorful yet high in fat

Usually only sold as whole & frozen

Ground Poultry

Healthy eating

Ground Chicken or Turkey

“Ground Turkey Breast” or “Ground Chicken”both meat and skin

“Ground Turkey Breast Meat” or “Ground

Chicken Meat”- only meat (no skin)

Can be substituted for ground beef- healthier yet drier (add more liquid/seasoning)

Giblets

Edible poultry organs

Liver, gizzard (stomach), and heart

Usually removed, packaged, and stuffed inside bird

Inspecting & Grading

USDA- United States Department of

Agriculture

Grade may appear on the package or attached to the wing of the bird

Grade A, B, or C

Grade A is the most common found in supermarkets—

Practically free of defects

Good shape and appearance

Meaty

Buying & Storing Poultry

Look for poultry w/ good appearance

High Quality Characteristics: plump, meaty, smooth and soft skin, well distributed fat, no tiny feathers, no bruises

Buy from a reliable source

Display of fish

Be sure that ice is covering all of the fish
