Use of near infrared hyperspectral tools for the screening of extractable polyphenols in red grape skins
(Elsevier, 2015)
Hyperspectral images of intact grapes were recorded at harvest time using a near infrared hyperspectral imaging system (900–1700 nm). Spectral data have been correlated with red grape skin extractable poly- phenols (total ...

Research Progress in Imaging Technology for Assessing Quality in Wine Grapes and Seeds
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
The chemical composition of wine grapes changes qualitatively and quantitatively during the ripening process. In addition to the sugar content, which determines the alcohol content of the wine, it is necessary to consider ...

Feasibility Study on the Use of a Portable Micro Near Infrared Spectroscopy Device for the “in Vneyard” Screening of Extractable Polyphenols in Red Grape Skins
(Elsevier, 2019)
There is substantial variation in levels of extractable phenolic compounds of red grapes (Vitis vinifera L.). Therefore, it could be desirable to known the aforesaid parameter at least for each vine. Nowadays, interest has ...

Feasibility study on the use of visible-near-infrared spectroscopy for the screening of individual and total glucosinolate contents in broccoli
(American Chemical Society, 2012)
The potential of visible-near-infrared spectroscopy to determine selected individual and total glucosinolates in broccoli has been evaluated. Modified partial least-squares regression was used to develop quantitative models ...

Comparative study on the use of anthocyanin profile, color image analysis and near-infrared hyperspectral imaging as tools to discriminate between four autochthonous red grape cultivars from la Rioja (Spain)
(Elsevier, 2015)
Three independent methodologies were investigated to achieve the differentiation of red grapes from different grape varieties (Garnacha, Graciano, Mazuelo and Tempranillo) collected from five vineyards located in the ...

Influence of Oak Wood Chips–grape Mix Maceration on the Extraction of Anthocyanins from Low‑extractable Anthocyanin Content Red Grapes
(Springer Nature, 2017)
Wine color depends not only on the amount of anthocyanin present in the grapes, but also on the amount of them that may be extracted from grapes and their interac- tions with other phenolic compounds. Color stabilization ...
