Kurkure packet's empty space is filled with an inert gas, in order to prevent it from

Options

A. reduction
B. oxidation
C. oxidation-reduction
D. precipitation

Explanation

### Step-by-Step Text Solution:

1. **Understanding the Question**: The question asks why Kurkure packets are filled with an inert gas. The options provided are to prevent oxidation, oxidation reduction, or to prevent precipitation.

2. **Identifying the Inert Gas**: The inert gas used in Kurkure packets is nitrogen. Nitrogen is commonly used in food packaging because it is non-reactive.

3. **Explaining the Role of Inert Gas**: The primary reason for filling the packets with nitrogen is to prevent the food from coming into contact with oxygen. Oxygen can cause various chemical reactions that lead to spoilage.

4. **Understanding Rancidity**: When food, especially those containing fats and oils, is exposed to oxygen, it can undergo oxidation. This process leads to rancidity, where the food develops an unpleasant taste and odor due to the breakdown of fats.

5. **Conclusion**: By filling the Kurkure packets with nitrogen, the oxidation process is inhibited, thus preventing rancidity and extending the shelf life of the product. Therefore, the correct answer to the question is that the inert gas is used to prevent oxidation.

### Final Answer:
The correct answer is **oxidation** (option 2).
