Question

The Time & Temperature combination is plane pasteurization

• A. 60 degree celcius for 30 minute
• B. 72 degree celcius for 15 seconds
• C. 72 degree celcius for 15 minute
• D. 121 degree celcius for 15 seconds

Answer 1

Answer:

B. 72 degree celcius for 15 seconds

• Pasteurization is a heat treatment process used to eliminate harmful microorganisms in food products, particularly milk and dairy products. The process involves heating the product to a specific temperature for a predetermined time to kill pathogenic bacteria while preserving the nutritional quality and taste.

• There are different methods of pasteurization:

  1. Low Temperature Long Time (LTLT) or Vat Pasteurization: 63°C (145°F) for 30 minutes

  2. High Temperature Short Time (HTST) or Flash Pasteurization: 72°C (161°F) for 15 seconds

  3. Ultra High Temperature (UHT): 135°C (275°F) for 2-5 seconds

• Option A (60°C for 30 minutes) is close to LTLT but not the standard temperature. Option C (72°C for 15 minutes) has the correct temperature but excessive time. Option D (121°C for 15 seconds) represents sterilization temperature, which would be too high for standard pasteurization.
