What is the name of the process where fatty foods become rancid?

Options

A. Corrosion
B. Oxidation
C. Reduction
D. Hydrogenation

Answer

To answer the question about the process where fatty foods become rancid, we can follow these steps:

### Step 1: Understand the Question
The question asks for the name of the process that causes fatty foods, such as butter and oils, to spoil or become rancid.

### Step 2: Analyze the Options
The options provided are:
1. Corrosion
2. Oxidation
3. Reduction
4. Hydrogenation

### Step 3: Evaluate Each Option
- **Corrosion**: This process typically refers to the deterioration of metals when they react with oxygen and moisture. It does not relate to food spoilage.

- **Oxidation**: This is a chemical process where a substance reacts with oxygen. In the context of fatty foods, oxidation leads to the formation of free radicals and peroxides, which spoil the food, causing off-flavors and odors, commonly referred to as rancidity.

- **Reduction**: This process involves a gain of electrons or a decrease in oxidation state. It is not related to the spoilage of fatty foods.

- **Hydrogenation**: This is a process where hydrogen is added to unsaturated fats to make them more saturated. This is not the process that causes rancidity.

### Step 4: Identify the Correct Answer
Based on the analysis, the correct answer is **Oxidation**. This is the process that causes fatty foods to become rancid.

### Final Answer
The name of the process where fatty foods become rancid is **Oxidation**.
