Question

The industrial High Pressure Processing setup consists of the following components;
(A). Pressure pump
(B). Pressure agitator
(C). Pressure chamber
(D). Pulse chamber
Choose the most appropriate answer from the options given below:

• A. (A), (B) and (D) only
• B. (A) and (D) only
• C. (A) and (C) only
• D. (B), (C) and (D) only

Hint:

Think of an HPP machine as a very simple but powerful system: you need something to make the pressure (\textbf{pump}) and something to hold the pressure (\textbf{chamber}). Other terms like "agitator" or "pulse chamber" are likely distractors from other technologies.

Answer 1

The Correct Option is C

Step 1: HPP Overview:
High Pressure Processing (HPP) is a non-thermal method of food preservation that uses high hydrostatic pressure to deactivate microorganisms and enzymes. An HPP system requires specific components to generate and maintain this pressure.
Step 3: HPP System Components:
Key components of an HPP system include:
- (A) Pressure pump: A high-pressure pump generates the required pressure (typically 400-600 MPa). This is the core of the system.
- (C) Pressure chamber: A robust, thick-walled steel cylinder that holds the packaged food submerged in a pressure-transmitting fluid (usually water). It's designed to safely contain the high pressure.
- (B) Pressure agitator: This term is incorrect in the context of HPP. Pascal's Principle dictates that pressure in an enclosed fluid is uniformly transmitted, eliminating the need for agitation.
- (D) Pulse chamber: This is a component of Pulsed Electric Field (PEF) processing, a different technology that uses electrical pulses, and is not used in HPP.
Step 4: Conclusion:
From the list, the essential HPP components are the pressure pump and the pressure chamber. Therefore, option (C) is the correct answer.
