Study on discrimination of white tea and albino tea based on near‐infrared spectroscopy and chemometrics

BACKGROUND White tea and albino tea have their own nutritional characteristics, but from the appearance they are quite similar to each other. It is not easy to distinguish them with existing analytical tools or by visual inspection. The current study proposed a rapid method to discriminate them based on near‐infrared ( NIR ) spectroscopy associated with supervised pattern recognition methods . RESULTS For this purpose, discriminant partial...
