Determination of the geographical origin of green coffee beans using NIR spectroscopy and multivariate data analysis
Food Control（2019）
摘要
In this work, near infrared (NIR) spectroscopy and multivariate data analysis were investigated as a fast and non-disruptive method to classify green coffee beans on continents and countries bases. FT-NIR spectra of 191 coffee samples, origin from 2 continents and 9 countries, were acquired by two different laboratories.
