Near-Infrared spectroscopy (NIRS) was used to determine the insoluble dietary fiber (IDF) content of moso bamboo shoot. A total of 120 samples were separated into two groups, as calibration set and prediction set. The IDF content of samples ranged from 0.046% to 0.209% were measured by AOAC 991.43 method. Spectral data from 400 nm to 1000 nm were collected using the samples. Three types of preprocessing...
The potential of Fourier transform infrared spectroscopy (FTIRS) combined with chemometrics for its ability to fast determine the total flavonoids content of rape bee pollen was studied. A total of 25 rape bee pollen samples were investigated for FTIRS on the wavenumber between 7800 and 350 cm-1. Direct orthogonal signal correction (DOSC) was performed to preprocess the original spectra data. Partial...
Two chemometric methods were performed for the determination of acetic acid of fruit vinegars using near infrared (NIR) spectroscopy. Three varieties of fruit vinegars were prepared and 135 samples (45 samples for each variety) were selected for the calibration set, whereas 45 samples (15 samples for each variety) for the validation set. Partial least squares (PLS) analysis was the calibration method...
