SHRINKAGE CONTROL AND COOKING TIME

THERE ARE TWO MAJOR FACTORS CONTROLL ING MEAT SHRIN KAGE OR COOKI NG LOSS ES.

1.Temperature at which meat is cooked :

The hig her the tem peratu re at which meat is cook ed the more shrin kage will result. Ove r-co oke d meat als o results in higher los ses. High er temp erat ures and over -co oking draw s moistu re to the surface and this moisture evap orate s or drip s out of the meat.

2.Intern al temperature of the meat:

Lik e over- coo king, as meat is brou ght to a hig her inter nal tem per atur e shri nkage is increased. For thes e two reason s, it is sugge sted most cuts of red meat be cook ed at 250°F (121° C) and that all cook ing be based on internal produ ct temperatur e. The use of a therm ometer is encourage d.

THER E ARE FOUR MAJOR FACTO RS INVOLVED IN DETERMI NING COO KIN G TIME S FOR MEAT:

1.The degree of aging on the meat:

Aged meat will cook faste r, shri nk more, and has a much short er holdi ng life than fres h meat .

2.Interna l temperature before cooking:

Meat sho uld be pla ced in a prehe ate d oven direct ly from a refrige rated tempe rature of 38° to 40°F

(3° to 4°C). Meat cooked from a froz en sta te will requi re approxima tely one and one -ha lf to two tim es the norma l cooking tim e. In addi tion, freez ing rupture s tissu e cells creating addit iona l moistu re loss duri ng the cooking proc ess and will resu lt in more shrink age.

3.Desire d degree of doneness:

The higher the deg ree of interna l temp erat ure requi red, the lon ger the nece ssary cooking tim e. Cooking tim es in this guid eline are bas ed on the most pop ular inter nal produ ct tem perat ures .
