Consider the following statements regarding the scientific aspects of vacuum packing:
- Humidity has no effect in vacuum packing.
- Oxidation reactions slow down due to the reduced oxygen content in vacuum packing.
- Some anaerobic microorganisms can grow even in vacuum conditions.
Which of the above statements are correct?
Correct answer: B
Explanation
Statement 1 is wrong because humidity and moisture do affect vacuum-packed food, influencing texture and microbial activity. Statement 2 is correct, since removing oxygen slows oxidation reactions that cause spoilage and rancidity. Statement 3 is also correct, as anaerobic microorganisms can still grow in low-oxygen vacuum conditions, which is why refrigeration is still needed.
