What is the primary use of Grade B milk?

• A. Liquid milk
• B. Butter and cheese
• C. Ice cream production
• D. Powdered milk

Answer: (B)

Grade B milk is primarily used for manufacturing products like butter, cheese, and other dairy derivatives rather than being sold as liquid milk for direct consumption. The classification of Grade B milk indicates that it does not meet the stringent quality standards required for fluid milk, which is intended for immediate human consumption. Instead, it is suitable for processing into other dairy products that undergo further treatment and can be safely consumed.

The other options mainly refer to products or uses that require higher quality standards and pasteurization processes that Grade B milk does not meet. For instance, liquid milk must conform to strict health and safety regulations, while ice cream production typically relies on Grade A milk for its higher quality. Powdered milk, while it can be made from both grades, is often derived from Grade A milk for the same reasons. Thus, Grade B milk's role is primarily in the production of processed dairy items like butter and cheese, making this answer the most appropriate choice.
