| Abstract: | The contents of total polyphenols in the six varieties blueberries,such as Elliott,Darrow,Patriot,Duke,Northblue and Bluecrop,were determined and analyzed by Fourier transform near infrared spectroscopy(FTNIR),and the near infrared calibration mathematics model of the content of total polypheols in blueberries was established by principal component analysis(PCA) and partial least squares(PLS),and the correlation coefficient was 0.9512 with calibration standard deviation of 0.72 and the prediction standard d... |
