What is a possible defect of U.S. Grade B dairy butter?

• A. Excessive salt content
• B. Slightly acid flavor or other defects
• C. No defects; highest quality
• D. Low fat content

Answer: (B)

U.S. Grade B dairy butter is characterized by its acceptable, though not premium, quality, which allows for certain flavor defects and other imperfections. A slightly acid flavor or other defects indicate that the butter does not meet the higher standards set for Grade A butter, which requires a superior flavor profile and overall quality. Grade B butter is still usable, particularly for cooking and baking, but it does not possess the same freshness and quality attributes as higher grades. This differentiation is essential for consumers and producers who need to understand the quality levels of dairy products available in the market.

The option regarding excessive salt content does not align as a defining defect for Grade B butter since salt levels can vary but are not specifically tied to the grade itself. The statement about highest quality being associated with Grade B is inaccurate, as Grade A clearly denotes the highest quality. Lastly, low fat content is not a defect since butter is expected to maintain a specific fat percentage, typically around 80-82%, regardless of grade.
