Cheese and yoghurt are products of

Options

A. Pasteurization
B. Fermentation
C. Dehydration
D. Distillation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks what processes are responsible for the production of cheese and yogurt.

2. **Identifying the Options**: The options provided are:
- Option 1: Pasteurization
- Option 2: Fermentation
- Option 3: Dehydration
- Option 4: Distillation

3. **Analyzing Each Option**:
- **Pasteurization**: This is a heat treatment process used to kill pathogens in food and beverages but is not directly involved in making cheese or yogurt.
- **Fermentation**: This is a metabolic process that converts sugar to acids, gases, or alcohol using microorganisms. It is the primary process used in the production of both cheese and yogurt.
- **Dehydration**: This process involves removing moisture from food to preserve it, but it does not relate to the making of cheese or yogurt.
- **Distillation**: This is a method used to purify liquids by heating and cooling, primarily used for water purification and not relevant to cheese or yogurt production.

4. **Conclusion**: Since cheese and yogurt are produced through the action of microorganisms (like bacteria and molds) that ferment sugars, the correct answer is **Option 2: Fermentation**.

5. **Final Answer**: Cheese and yogurt are products of fermentation.
