Inspecting Beef Grading Beef ‘Branding’ Beef Enhancing Beef Color of Beef

Beef Inspection  Began in 1891  Responsibility of the Food Safety and Inspection Service (FSIS), the public health agency for the USDA  Considered by many to be the most regulated segment of the food industry

Beef Inspection  Federal Meat Inspection Program  Mandatory (paid for by taxpayers)  Ensures only meat from healthy animals enters food chain  Ensures facilities and equipment meet sanitation standards  U.S. inspected and passed stamp on each primal  On outside of container if packaged  Includes official establishment number of processing plant

Producing Wholesome Beef  The beef industry is committed to producing the safest products possible  Includes everyone:  Livestock producer (Beef Quality Assurance Program)  Packer/processor (USDA-FSIS oversight and HACCP implementation)  Wholesaler/retailer operations (cold chain management)  Foodservice operator or consumer (ServSafe®, proper cookery)

Kosher Beef  Dietary standard for those practicing Judaism under Islamic law  Hebrew meaning “fit and proper” or “properly prepared”  Processed under supervision of a rabbi; independent of the requirements for federal/state meat inspection  Hindquarter cuts not available as kosher  Kosher inspection stamp applied after meeting kosher and federal/state inspection requirements

Halal Beef  Arabic meaning “lawful” or “permitted”  Dietary standard for practicing Muslims under Islamic law  Animal or poultry must be harvested in a ritual called Zibah  Animal must be alive and healthy at time of harvest  Harvest must be performed by a Muslim  Halal or Zabiah Halal labels must be handled according to Islamic law under Islamic authority  Independent of the requirements for federal/state meat inspection

Federal Meat Grading Program  USDA meat grading program  Established in 1927  Administered by the USDA’s Agricultural Marketing Service (AMS)  Sets “standards” of quality and cutability  Generates federal grade standards for beef and veal  Grading is voluntary (meat inspection is mandatory)  Paid for by meat packers  Provides operator with a prediction of palatability  Tenderness, juiciness, flavor

Quality and Yield Grades  8 Quality Grades  3 most familiar: Choice, Select and Prime  5 remaining: Standard, Commercial, Utility, Cutter and Canner  Less than 1% of older cattle that could qualify for Commercial or Utility are graded

SOURCE: USDA, 2010

 5 Yield Grades  1=leanest  5=fattest

What’s Graded?  Beef carcass, not individual cuts  Grade carries forward to all wholesale/primal and portion cuts derived from graded carcass  Roughly 95% of all federally inspected slaughter gets a grade

Rolled and “No Roll” Beef  Rolled:  Graded carcass “rolled” with blue ink stamp or shield to designate grade  Rolled along back from Round to Chuck and over the clod and brisket  No Roll:  Ungraded carcass  No official USDA grade standard  No official “no roll” stamp

Lower Quality Still Valuable  Carcasses from lower quality grades not typically graded  Wholesome and nutritious, but less tender  Commonly used in  Ground beef  Sausages  Other manufactured meat products  The best cuts/subprimals of lower grades may be tenderized and used in lower-priced beef entrées

Carcass Fat 



Plays important role in determining quality and yield grades Types of fat:  Marbling (intramuscular)  Fat deposited within the muscle  Important factor in determining quality grade  Last area for fat to be deposited  External (subcutaneous)  Covers outside of the carcass  Has negative impact on final yield grade  Seam (intermuscular)  Lies between muscles  Has negative impact on final yield grade  Internal (KPH)  Protects internal organs  Has negative impact on final yield grade

Slightly abundant marbling

Moderate marbling

Small marbling

The Final Word About Quality Relationship Between Marbling, Maturity, and Carcass Quality Grade*

Degrees of Marbling Slightly Abundant Moderate Modest Small Slight Traces Practically Devoid

* Assumes that firmness of lean is comparably developed with the degree of marbling and that the carcass is not a “dark cutter.” ** Maturity increases from left to right (A through E). *** The A Maturity portion of the figure is the only portion applicable to bullock carcasses. SOURCE: USDA

A Word About Yield Grading  



 

Performed by same USDA grader who determines quality grade Identifies differences in carcass cutability  Cutability: the amount of saleable meat obtained from the carcass as boneless, trimmed retail cuts USDA Yield Grades and Quality Grades are “rolled” onto the beef carcass at the same time Useful at purchasing level Lower yield grade number translates to:  Smaller cutting loss  Less seam fat within individual cuts  Higher cooking yield Yield Grade 1

greatest amount of saleable meat

Yield Grade 5

least amount of saleable meat

Certification – Assists Branding  “Branding” is increasingly popular  Agricultural Marketing Service (AMS)  Provides voluntary certification services  Provides for certification of specific carcass characteristics within each program’s published requirements  Provides confidence that claims made were substantiated by independent 3rd party oversight  Currently has approved certification services for 60+ beef programs

Aging  A natural enzymatic process that occurs in all muscles after harvesting  Two types of aging:  Dry  Wet (vacuum packaged)  Research suggests that tenderness of cooked beef can be affected by:  Individual muscles  USDA quality grade  Length of aging time

Enhanced Beef  Meat is soaked, massaged, tumbled and/or injected with a marinade to:  Enhance tenderness or juiciness  Impart other attributes, such as color or flavor  All prepackaged products must disclose on the label the amount of marinade and the ingredients used

Enhancement Ingredients 







Primary ingredients are:  Water  Salt  Phosphates These ingredients affect:  Texture  Water-holding capacity (increases it)  Meat proteins = 20% of beef’s composition and can hold 4X their weight in water Secondary ingredients are:  Seasonings  Acids  Sweeteners Results:  Impart unique flavors  Improve visual appearance  Provide extended shelf life

Dark Beef: A Natural Phenomenon  Abnormally dark color, generally the result of reduced glycogen (muscle “sugar”) when animal is harvested  Causes:  Excessive animal stress prior to harvest  Stressful conditions (i.e., severe weather changes)

 Effects:  Does not affect eating quality  Higher muscle pH (less acid) after carcass is chilled  May receive one full grade lower

Quality Not Affected    

About 2% of steers and heifers are dark cutters Acceptable for many foodservice applications Appears the same as “normal” colored beef after cooking Does NOT have as long of a shelf-life

Beef Color Myoglobin  A protein in muscles, similar to hemoglobin, the oxygen-carrying protein in blood  Various amounts give meats their distinctive colors Myoglobin in a Gram of Meat Meat

Oxygen & Color  Beef muscle not exposed to air (oxygen) is a purplish-red color  Foodservice operator will recognize a color change with vacuum-packaged beef cuts  Sealed bag, color appears purple-red  Opened bag, “blooms” to bright, cherry-red  Fresh meat exposed to oxygen for a longer period of time may change to a “brownish” color  Chemical change is called oxidation  Color can toggle between purple and red but once it changes to brown, it cannot go back

Color and Meat Cookery  Myoglobin, along with other meat proteins, “denatures” when cooked  The higher the internal temperature of the meat, the less red the cooked meat becomes, reflecting the “degree of doneness” of the cooked meat

Iridescent Beef    

Rainbow color in raw and cooked beef Naturally occurring phenomenon Does not affect quality or palatability Created by interference of light waves reflected off the meat’s surface  Smooth meat surfaces may exhibit iridescence more vividly than rough surfaces  Common in Roast Beef and Eye Round

Beef Color Dynamics  Persistent pinking - cooked fresh meats that remain red on the surface or interior despite being fully cooked  i.e. meatloaf that remains pink even when fully cooked  Scientifically proven causes are:  Traces of nitrates in water supplies  Traces of nitrites and nitrates in vegetables  Use of pepper solution (which may contain a trace of natural nitrate)  Presence of carbon monoxide in heating gases and exhaust gases may lead to the red ring on cooked meats

Summary  Inspection is mandatory; federally administered  Grading for quality and yield is voluntary  Aging and marinating enhance beef's tenderness and flavor  Color of meat is an important factor
