Description

This dataset contains Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR) spectral data of coffee silverskin obtained from specialty coffees processed under wet and semi-wet postharvest treatments at different temperatures and fermentation times. Raw spectra is provided together with R scripts for exploratory analysis using Principal Component Analysis (PCA). The dataset supports chemometric analysis, spectral fingerprinting, and the development of data-driven and model-based approaches for coffee by-product valorization.
