Abstract

UV-Vis spectroscopy has been used as a promising method for coffee quality evaluation including in authentication of several high-economic coffee types. In this paper we have compared the abilities of linear discriminant analysis (LDA) and support vector machines classification (SVMC) methods for luwak coffee classification. UV-Vis spectral data of 50 samples of pure luwak coffee and 50 samples of pure non-luwak coffee were acquired using a UV-Vis spectrometer in transmittance mode. The results show that UV-Vis spectroscopy combined with LDA and SVMC was effective method to classify luwak and non-luwak coffee samples. The classification result was acceptable and yielded 100% classification accuracy for both LDA and SVMC methods. However, due to the simplicity and volume of required calculation, in this present study LDA method is superior to SVMC method.
