Prediction of Zamorano cheese quality by near-infrared spectroscopy assessing false non-compliance and false compliance at minimum permitted limits stated by designation of origin regulations

► A fast method is proposed to determine fat, dry matter and protein contents in cheese. ► Zamorano cheese is a European PDO so assessing its quality is mandatory. ► Evaluating the probability of false compliance is possible from NIR signals and PLS. ► Minimum permitted limits set by quality regulations are ensured with NIR and PLS.
