Measurement of Titratable Acidity in Gannan Navel Orange by near Infrared Spectroscopy

Article Preview

Abstract:

To explore a rapid and non-destructive method for measuring titratable acidity in Gannan Navel Orange, near infrared spectroscopy combined with partial least square method was adopted for building a prediction model. Multiple statistical analysis results show that when the optimal spectral region (950-1330nm) was selected for modeling, the correlation coefficient of the validation set is 0.9085, and RMSECV is 0.0243g/100g. This technique using near infrared spectroscopy is rapid, convenient and nondestructive, and may potentially become a strong tool for the quality evaluation and fruit sorting of navel oranges.
