Why does ground beef turn brown in the center but stay red on the outside?
Ground beef is a staple in many cuisines, but have you ever wondered why it often turns brown in the center while maintaining a pinkish hue on the outside? This phenomenon occurs due to the way oxygen reacts with the protein myoglobin, a pigment responsible for its red color. When you grind beef, you break down the muscle fibers, releasing this pigment. When exposed to oxygen, the myoglobin undergoes a chemical reaction, causing it to oxidize, which turns it brown. This reaction happens more rapidly on the surface, where oxygen is more readily available. In contrast, the center remains relatively oxygen-deprived, allowing the myoglobin to maintain its original red color. This explains why, when you cook a burger or meatball, the outside often appears cooked before the inside reaches the desired level of doneness. To ensure food safety, always cook ground beef to an internal temperature of at least 160°F (71°C) to prevent potential bacterial contamination.
Can cooking ground beef kill bacteria if it’s already brown?
Browning ground beef is an important step in cooking, but it’s essential to ensure that the cooking process is thorough and safe to prevent bacterial growth and foodborne illness.
