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 ...

Application of imaging techniques for the evaluation of phenolic maturity of grape seeds
(Sociedad Española de Óptica, 2017)
Quality of wine depends fundamentally on the condition of the components of grapes at the moment of harvest. In this respect, their seeds directly affect to structure, astringency, stability, and indirectly to colour of ...
