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 ...

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 ...
