Geographical indication, a type of intellectual properties, plays a pivotal role in modern world trades. It is a tool that can very well sustain the value of local products. In a research led by Assoc. Prof. Dr. Thanit Praneenararat, the analysis of chemical constituents in Thai coffees was performed using paper spray mass spectrometry. This resulted in a creation of a chemical database that can be used to effectively discriminate geographical origins of coffees by chemometrics. For example, successful classifications (85-100% in almost all cases) were obtained for the discrimination of Arabica vs Robusta coffees, the discrimination of countries of origin, and the discrimination of geographical locations within the same province. This study is a practical example of how chemistry can help increase sustainability in other industries of wide impact.
