Certified Cheese Professional Practice Exam

Which type of milk has the highest lactose percentage?

1. Buffalo milk

2. Cow milk

3. Sheep milk

4. Goat milk

The correct answer is: Sheep milk

Sheep milk is known for having a higher lactose content compared to the other types listed. While cow, goat, and buffalo milk all contain lactose, sheep milk typically has a higher concentration, which can be attributed to its rich nutrient profile. This increased lactose percentage contributes to the unique flavor and texture of sheep milk cheeses, making them distinct in the cheese-making process. Buffalo milk, while also rich and creamy, does not surpass the lactose percentage found in sheep milk. Cow milk generally has less lactose than sheep milk, and goat milk, although similar to cow milk, still tends to have lower lactose levels than sheep milk. Thus, the higher lactose content in sheep milk sets it apart from the other options.
