The unique properties of heme make it an essential molecule in many biological processes, including energy production and oxygen transport.
What Makes Heme Special?
Heme’s significance extends beyond its biological functions. It is also responsible for the characteristic color, flavor, and aroma of meat. When heme is exposed to heat, it undergoes a chemical reaction that creates the distinctive taste and smell of cooked meat. This is because heme contains a molecule called iron, which is essential for the formation of these compounds. In plant-based meat alternatives, heme is used to replicate the sensory experience of eating meat, making it a crucial ingredient in products like Impossible Burgers.
The Science Behind Heme’s Role in Flavor and Aroma
The flavor and aroma of meat are complex and multifaceted, involving a wide range of molecules and chemical reactions. When meat is cooked, the heat breaks down the proteins and fats, releasing volatile compounds that contribute to the characteristic smell and taste. Heme plays a central role in this process, as it reacts with other molecules to form new compounds that are responsible for the flavor and aroma of cooked meat. In plant-based meat alternatives, manufacturers use heme to mimic this process, creating a flavor and aroma profile that is similar to meat.
