Fourier transform (FT) near-infrared (NIR) and attenuated total reflection (ATR) FT mid-
infrared (MIR) spectroscopy were used to qualitatively and quantitatively analyse Vitis …

The potential of visible-near infrared (vis/NIR) spectroscopy (400 nm to 1100 nm) for
classification of grape berries on the basis of multi inner quality parameters was …

Texture characteristics are valuable parameters in the perceived quality and overall
acceptability of fresh fruit. The characterization of grape texture attributes, such as firmness …

The content of phenolic compounds determines the state of phenolic ripening of red grapes
and is a key criterion in setting the harvest date to produce quality red wines. In this study …

BACKGROUND Recent studies have reported the potential of near infrared (NIR) spectral
analysers for monitoring the ripeness of grape berries as an alternative to wet chemistry …

Changes in the chemical properties of wine grapes during ripening were studied using near-
infrared (NIR) spectroscopy. A miniature fiber-optic NIR spectrometer system working in …

Red wine grapes require a constant follow-up through analytical chemistry to assure the
greatest wine quality. Wet chemical procedures are time-consuming and produce residues …

Infrared spectroscopy provides extensive spectral and chemical information for plant
material. However, the raw spectral data of fresh grapevine organs are poorly understood …

The aim of this study was to evaluate the usefulness of visible (VIS), near-infrared
reflectance (NIR) and mid-infrared (MIR) spectroscopy combined with pattern recognition …

The potential of near infrared spectroscopy (NIRS) in the wavelength range of 1000–2500
nm for predicting quality parameters such as total soluble solids (TSS), acidity (TA), firmness …
