| SHRINKAGE CONTROL AND COOKING TIME |
|
|
| |
| THERE ARE TWO MAJOR FACTORS CONTROLLING | THERE ARE FOUR MAJOR FACTORS INVOLVED IN |
| ||
| MEAT SHRINKAGE OR COOKING LOSSES. | DETERMINING COOKING TIMES FOR MEAT: |
| ||
| 1. | Temperature at which meat is cooked: | 1. | The degree of aging on the meat: |
|
|
| The higher the temperature at which meat is cooked |
| Aged meat will cook faster, shrink more, and has a |
|
|
| the more shrinkage will result. |
| much shorter holding life than fresh meat. |
|
|
| also results in higher losses. Higher temperatures | 2. | Internal temperature before cooking: |
|
|
| and |
| Meat should be placed in a preheated oven directly |
|
|
| this moisture evaporates or drips out of the meat. |
| from a refrigerated temperature of 38° to 40°F |
|
| 2. | Internal temperature of the meat: |
| (3° to 4°C). Meat cooked from a frozen state will |
|
|
| Like |
| require approximately one and |
|
|
| internal temperature shrinkage is increased. For |
| the normal cooking time. In addition, freezing |
|
|
| these two reasons, it is suggested most cuts of red |
| ruptures tissue cells creating additional moisture |
|
|
| meat be cooked at 250°F (121°C) and that all cooking |
| loss during the cooking process and will result in |
|
|
| be based on internal product temperature. The use |
| more shrinkage. |
|
|
| of a thermometer is encouraged. | 3. | Desired degree of doneness: |
|
|
|
|
| The higher the degree of internal temperature |
|
|
|
|
| required, the longer the necessary cooking time. |
|
|
|
|
| Cooking times in this guideline are based on the |
|
|
|
|
| most popular internal product temperatures. |
|
|
|
| 4. Quantity and quality of product. |

TO CALCULATE MEAT SHRINKAGE
STARTING WEIGHT (Weight of Raw Product)
EQUALS: AMOUNT OF SHRINKAGE
AMOUNT OF SHRINKAGE (Total Weight Lost in Cooking)
÷DIVIDED BY: STARTING WEIGHT (Weight of Raw Product)
EQUALS: PERCENT OF SHRINKAGE

PREVENTING BACTERIA GROWTH
The surface of raw meat may become contaminated in processing, handling by the butcher or chef, or by other means. Food contamination can also be caused by unsanitary personal hygiene and work habits, unclean slicers, knives, and probes, or by faulty operational procedures. It is important, therefore, that
sanitary procedures be followed at all times during food preparation and handling. This is your main protection in guarding against food contamination. For additional information see the Cleaning and Maintenance section of this manual.
