Question

The normal pressure maintained in the HTST system for pasteurized milk.

• A. 10 psi
• B. 12 psi
• C. 15 psi
• D. 20 psi

Hint:

HTST systems maintain higher pressure on pasteurized side to prevent contamination.

Answer 1

The Correct Option is C

Concept: HTST pasteurization requires maintaining pressure to prevent contamination and ensure proper flow direction.

Step 1: Purpose of pressure.

• Prevents raw milk contamination
• Ensures pasteurized milk remains in sterile section

Step 2: Standard value.
Typical pressure: \[ 15 \, \text{psi} \]

Step 3: Conclusion.
Thus, correct answer is 15 psi.
