Tag: Amino acids in coffee

While green coffee beans contain a significant amount of storage protein, primarily 11S globulin, most of it is destroyed or fundamentally altered during the high-temperature roasting process. Consequently, a standard cup of brewed Java coffee contains only trace amounts of protein.

A typical cup of plain black coffee contains only a negligible amount of protein, roughly 0.3 grams per serving. This fact immediately suggests that coffee is not a significant source of protein, and by extension, the building blocks of protein—amino acids. Thus, the straightforward answer to “**Is coffee high in amino acids?**” is a definitive no.
