| Abstract | This paper proposes a new method for the quantitative analysis of date seed coffee in a binary mixture with Arabica coffee by applying Attenuated Total Reflectance-Fourier Transform Mid Infrared Spectroscopy (ATR-FTMIR) associated with chemometric tools. Blends of Arabica coffee with different percentages of Date seed coffee were measured using ATR-FTIR spectroscopy. Spectral and reference data were firstly analyzed by principal component analysis (PCA). Partial least square regression (PLSR) was used to establish calibration model. Excellent correlation between ATR-FTIR analysis and studied coffee blends was obtained R 2 = 0.99; with Root Mean Square Errors of Prediction < 2.31, Limit of Detection 6.912%, and Relative Prediction Errors as low as 0.21. This result demonstrated the feasibility of ATR-FTIR spectroscopy combined with chemometrics to quantify successfully binary mixtures of Arabica coffee in the 7–50 % weight ratio range of Date seed coffee with a reliable, rapid and inexpensive tool without the need for sample preparation. |
