A penetrometer is an instrument used to measure the tenderness of meat, specifically by measuring the force required to penetrate a piece of meat. This device is commonly used in food quality testing to determine how tender or soft a piece of meat is, which is an important quality attribute for meat consumers.
- Option (2) refers to measuring the taste of meat, but this is not what a penetrometer is used for.
- Option (3) refers to measuring the color of meat, but again, this is not the function of a penetrometer.
- Option (4) refers to measuring the quantity of meat, which is not the purpose of a penetrometer either.
Thus, the correct answer is option (1): Measure the tenderness of meat.
