Answer

To determine which of the following is used as a preservative to protect processed food, we will analyze the options provided in the question and the information from the video transcript.

### Step-by-Step Solution:

1. **Identify the Options**: The question asks which substance is used as a preservative. The options mentioned in the transcript include:
- Securin
- Methylated Hydroxyanisole
- Omreloxifene
- Cochineal

2. **Analyze Each Option**:
- **Securin**: The transcript describes Securin as an artificial sweetener, not a preservative. It is used as a sugar substitute and does not prevent food spoilage.
- **Methylated Hydroxyanisole (BHA)**: The transcript states that Methylated Hydroxyanisole is used to prevent rancidity in food. This means it acts as an antioxidant, which helps to protect food from oxidation and spoilage, making it a preservative.
- **Omreloxifene**: This compound is mentioned in the transcript as being used to control population and is not related to food preservation.
- **Cochineal**: The transcript indicates that Cochineal is used as a natural food colorant and in dyes, but it is not primarily a preservative.

3. **Conclusion**: Based on the analysis, the only substance from the options that is used as a preservative to protect processed food is **Methylated Hydroxyanisole**.

### Final Answer:
**Methylated Hydroxyanisole** is used as a preservative to protect processed food.
