Reduction of the Number of Samples for Cost-Effective Hyperspectral Grape Quality Predictive Models
(MDPI, 2021-01)
Developing chemometric models from near-infrared (NIR) spectra requires the use of a representative calibration set of the entire population. Therefore, generally, the calibration procedure requires a large number of ...

Estimation of Total Phenols, Flavanols and Extractability of Phenolic Compounds in Grape Seeds Using Vibrational Spectroscopy and Chemometric Tools
(MDPI, 2018)
Near infrared hyperspectral data were collected for 200 Syrah and Tempranillo grape seed samples. Next, a sample selection was carried out and the phenolic content of these samples was determined. Then, quantitative (modified ...

Simplified method for the screening of technological maturity of red grape and total phenolic compounds of red grape skin: Application of the characteristic vector method to near-infrared spectra
(American Chemical Society, 2015)
Characteristic vector analysis has been applied to near-infrared spectra to extract the main spectral information from hyperspectral images. For this purpose, 3, 6, 9, and 12 characteristic vectors have been used to ...

Screening of anthocyanins in single red grapes using a non-destructive method based on the near infrared hyperspectral technology and chemometrics
(John Wiley and Sons Ltd, 2016)
BACKGROUND:Anthocyanins are the main compounds responsible for the colour of red wines and therefore itmay be important to evaluate the contentof the aforesaid secondary metabolites duringgraperipeningdueto the crucial ...
