Milk is considered Ultra-High Temperature pasteurized if it reaches:

1) 145 degrees F (63 degrees C) for 30 minutes

2) 194 degrees F (90 degrees C) for 0.5 seconds

3) 212 degrees F (100 degrees C) for 1 second

4) None of the above

Answer :

Final answer:

Milk is considered Ultra-High Temperature pasteurized if it reaches a temperature of 140°C (284°F) for four seconds. This method of pasteurization allows milk to be stored without refrigeration for extended periods of time.

Explanation:

Milk is considered Ultra-High Temperature pasteurized if it reaches a temperature of 140°C (284°F) for four seconds. During UHT processing, milk is sterilized rather than pasteurized by exposing it to high-temperature steam under pressure. This process allows milk to be stored for several months without refrigeration. UHT pasteurized milk is labeled as such to indicate it has undergone this specific method of pasteurization.
