The study found a way to accurately measure the amount of arabica and robusta coffee in blends using a method called 1H-NMR analysis. By looking at different chemical components, they could tell the composition of the blends, regardless of where the coffee came from. This method can help verify if a coffee blend contains the right mix of arabica and robusta.
