These regions were selected since green coffee beans from these locations are commonly sold in Japan supermarkets. Samples of green coffee beans produced in seven locations-Cuba, Ethiopia, Indonesia (Bari, Java, and Sumatra), Tanzania, and Yemen-were analyzed. Soft independent modeling of class analogy (SIMCA) was applied as the classification method. Therefore, in this study, we focused on determining the production area (five areas and three districts) of green coffee beans using classification analysis and NIRS. In the food industry, it is important to know the district in which a particular food was produced. Near-infrared spectroscopy (NIRS) is a powerful tool for the nondestructive evaluation of organic materials, and it has found widespread use in a variety of industries.
