Evaluation of extractable polyphenols released to wine from cooperage byproduct by near infrared hyperspectral imaging
(Elsevier, 2018)
Extractable total phenolic content of American non-toasted oak (Quercus alba L.) shavings has been determined using near infrared hyperspectral imaging. A like-wine model solution was used for the simulated maceration ...

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 ...

Optimization of Protein Extraction of Oenological Interest from Grape Seed Meal Using Design of Experiments and Response Surface Methodology
(MDPI, 2021)
After grape processing, large amounts of seeds are produced as a side product. Grape seeds are rich in proteins that could be extracted and revalorized by the wine industry due to their high techno-functional value for ...

Study of Phenolic Extractability in Grape Seeds by Means of ATR-FTIR and Raman Spectroscopy
(Elsevier, 2017)
Near infrared hyperspectral imaging has been applied to grape seeds in order to select a representative subset of samples according to their spectral features in the 900–1700 nm range. Afterwards, selected grape seeds have ...

Linking ATR-FTIR and Raman features to phenolic extractability and other attributes in grape skin
(Elsevier, 2017)
The importance of wine phenolics on the sensory characteristic of red wines is well-known. Therefore, it is necessary to control the extractability of phenolic compounds from grape skins, which depends significantly on ...

Phenolic Compounds Extraction in Enzymatic Macerations of Grape Skins Identified as Low-level Extractable Total Anthocyanin Content
(Wiley-Blackwell, 2020)
Anthocyanins in wine principally depend on grape skin extractable anthocyanin content, that is, the amount of anthocyanins present in grape skin that are released to wine during the maceration stage. This amount of extractable ...

Screening of Wine Extractable Total Phenolic and Ellagitannin Contents in Revalorized Cooperage By-products: Evaluation by Micro-NIRS Technology
(Springer, 2019)
Determining phenolic compounds of wood and its extractability to the hydroalcoholic medium is important in the oenological industry. The method proposed in this study copes with this issue in an in situ, non-destructive, ...
