What percentage of proteins typically make up the composition of green arabica coffee?

• A. 8%
• B. 10%
• C. 15%
• D. 50%

Answer: (B)

Green arabica coffee typically contains around 10% proteins in its composition. This percentage is significant as proteins play essential roles in the coffee bean, influencing flavors, aromas, and overall quality during the brewing process. The proteins in coffee can also interact with various compounds during roasting, contributing to the development of new flavors as well as affecting the crema and mouthfeel.

Understanding the protein content in coffee is crucial for roasters, as it helps inform decisions about roasting profiles that can enhance flavor complexity. While other options suggest different protein levels, 10% aligns closely with typical analyses of green arabica beans, making it the correct choice in understanding the composition of these beans.
