  1. PSE

  2. DFD

  3. Rigor mortis

  4. Overcooking
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

PSE (pale, soft, and exudative) is the term for the condition in which meat becomes pale, soft, and exudative due to rapid post-mortem pH decline. This occurs when the muscle glycogen is rapidly converted to lactic acid, causing a rapid decrease in pH.

Multiple choice

What is the term for the condition in which meat becomes dark, firm, and dry due to delayed post-mortem pH decline?

  1. PSE

  2. DFD

  3. Rigor mortis

  4. Overcooking
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

DFD (dark, firm, and dry) is the term for the condition in which meat becomes dark, firm, and dry due to delayed post-mortem pH decline. This occurs when the muscle glycogen is not rapidly converted to lactic acid, resulting in a slow decrease in pH.
