Question

A flexible pouch capable of withstanding temperatures of about 120 \(^{\circ}\)C is known as __________

• A. High barrier plastic
• B. Microwave-ovenable package
• C. Retortable pouch
• D. Aseptic pouch

Hint:

Associate the word "retort" with high-temperature sterilization (like a pressure cooker). A "retortable pouch" is essentially a flexible can, designed to go through this process.

Answer 1

The Correct Option is C

Step 1: Concept Overview:
The question refers to packaging used for thermal sterilization. The temperature of 120 \(^{\circ}\)C (specifically 121 \(^{\circ}\)C or 250 \(^{\circ}\)F) is standard for commercial sterilization of low-acid foods in a retort or autoclave.
Step 3: Detailed Explanation:
- Retortable pouch: A flexible, laminated pouch designed to endure the high temperatures and pressures of retorting (autoclaving). It's used for shelf-stable, thermally processed foods as an alternative to metal cans.
- High barrier plastic: This refers to a material property (e.g., resistance to oxygen or moisture), not a specific package type. Retort pouches utilize high-barrier plastics, but that's not the pouch's name.
- Microwave-ovenable package: Designed for microwave reheating; lacks the strength for retort temperatures.
- Aseptic pouch: A package filled with a pre-sterilized product in a sterile environment. The package isn't heat-treated after filling.
Step 4: Conclusion:
A flexible pouch designed to withstand sterilization temperatures around 120 \(^{\circ}\)C in a retort is a retortable pouch. Thus, option (C) is correct.
