Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Minimal processing technologies refer to non-thermal or low-temperature food preservation techniques designed to extend shelf life while maintaining fresh-like nutritional and sensory qualities.
Step 2: Detailed Explanation:
- Sous vide (A) is a minimal thermal treatment of raw materials packed in vacuum pouches at precise low temperatures, minimizing nutrient loss.
- High Pressure Processing (B) is a non-thermal pasteurization technique that inactivates vegetative microorganisms using hydrostatic pressure without heat-induced degradation.
- Pulsed Electric Fields (C) utilize short high-voltage pulses to permeabilize microbial cell membranes non-thermally.
- Radio Frequency Heating (D), in contrast, is an energetic thermal processing technology that relies on electromagnetic waves to rapidly generate high temperatures inside the food, which does not fall under minimal or non-thermal processing.
Step 3: Final Answer:
Therefore, A, B, and C are considered minimal processing technologies.
