A common adulterant is black papaya seeds. Researchers in Peru and Brazil have investigated the potential of near infrared hyperspectral imaging (NIR-HSI) combined with multivariate analysis to identify black pepper adulterated with papaya seeds. SIMCA (soft independent modelling of class analogy) allowed classification with 100% sensitivity between berry black pepper and berry papaya seeds. A PLS (partial least squares) reduced model based on 7 wavelengths presented higher predictive capability, and the maps from this model successfully showed the distribution of ground papaya seeds in ground black pepper.</p>
