close routine
1.The determination coefficients (R~2) of the predicted models for Brix and reducing sugars in juice were (0.999 0) and (0.995 3), respectively; the root mean square errors of cross validation were (0.115 0)% and (0.072 2)% for Brix and reducing sugars in juice, respectively. The predictive errors measured by FT-NIR methods were close to those by routine laboratory methods.
