Title: FOODS 2

Beef
  • FOODS 2
  • Mrs. Raterman

2
Types of Meat
  • 1. Beef comes from mature cattle over 12
    months of age.
  • Wholesale cuts a large cut of meat shipped to a
    retail grocery store or a meat market.
  • Retail cuts a smaller cut of meat taken from a
    larger wholesale cut and sold to consumers in
    retail stores.
  • Ground beef fat content cannot be more than 30

3
Types (continued)
  • 2. Veal comes from young cattle less than 3
    months of age.
  • Very little fat light pink color and a delicate
    flavor.

4
Inspection and Grading
  • All meat shipped across state lines must be
    examined.
  • Quality grades based on marbling, maturity,
    texture, and appearance.
  • Marbling flecks of fat throughout the lean
    portions seen as little white streaks or drops.

5
Top 3 USDA Grades for Beef
  • USDA Prime the highest grade tender, juicy,
    and flavorful greatest marbling, served in fine
    restaurants and some meat stores.
  • USDA Choice high quality good marbling,
    slightly less than prime found in retail stores.
    Sufficient marbling for taste and tenderness.
  • USDA Select has the least marbling lower cost.
    Leaner, not as juicy, tender, or flavorful.

There are basically two types of meat dark and
white
  • Red, or dark meat is made up of muscles with
    fibers that are called slow-twitch. These muscles
    are used for extended periods of activity, such
    as standing or walking, and need a consistent
    energy source.
  • The protein myoglobin stores oxygen in muscle
    cells, which use oxygen to extract the energy
    needed for constant activity. Myoglobin is a
    richly pigmented protein. The more myoglobin
    there is in the cells, the redder, or darker, the
    meat.

11
Dark Meat Cont.
  • When dark meat is cooked, myoglobin's color
    changes depending on what the meat's interior
    temperature is. Rare beef is cooked to 140 F,
    and myoglobin's red color remains unchanged.
  • Above 140 F, myoglobin loses its ability to bind
    oxygen, and the iron atom at the center of its
    molecular structure loses an electron.

12
White Meat
  • White meat is made up of muscles with fibers that
    are called fast-twitch. Fast-twitch muscles are
    used for quick bursts of activity, such as
    fleeing from danger. These muscles get energy
    from glycogen, which is also stored in the
    muscles.
  • White meat has a translucent "glassy" quality
    when it is raw. When it's cooked, the proteins
    denature and recombine, or coagulate, and the
    meat becomes opaque and whitish.

13
White Meat
  • Cows and pigs are both sources of dark meat,
    though pig is often called "the other white
    meat." Pigs' muscles do contain myoglobin, but
    the concentration is not as heavy as it is in
    beef.
  • Chickens have a mixture of both dark and white
    meat, and fish is mainly white meat.

14
Tenderizing Meat
  • External treatments can be applied to meats to
    increase their tenderness. These include the use
    of enzymes, salts, acids, and mechanical methods
    such as grinding or pounding.

15
Enzymes
  • Enzymes are sprinkled on meat, which is then
    pierced with a fork to drive the enzymes below
    the surface.
  • Sold as salt or liquid mixtures that contain
    papain from papayas, bromeline from pineapples,
    ficin from figs, and rhyozyme from fungi.

16
Salts
  • Brining meat (that is, putting meat into a
    salt-water solution) adds moisture to the meat.
    Brining adds salt and water to the cells so that
    When the meat is cooked and water is squeezed
    out, there is still water left in the cells
    because water was added before cooking.

17
Acids
  • Marinades
  • Vinegar, wine, and lemon, tomato, or other fruit
    juices.
  • Not only tenderize meat but add flavor
  • Meat should be cut into small pieces, such as
    teriyaki or kabobs.

18
Mechanical Tenderization Electronic Stimulation
  • Meat can be tenderized mechanically by a number
    or methods, including, grinding, cubing,
    needling, and pounding.
  • A electric current is passed through the carcass
    after slaughtering.
