By setting different temperature ,on baking treatment of Black Tea ,a study has been conducted on the change of the tea red pigment .The standard normal variate transformation (SNV) ,SG smooth der‐ivation ,multiplicative scatter correction (MSC) ,mean centering on the near infrared spectra have been used to preprocess the near infrared spectra .And the modeling has been constructed by means of partial least squares (PLS) ,with the correlation coefficient of the model reaching 0 .993 ,to illustrate the model‐ing effect is good .
