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 ...

Use of Hyperspectral Imaging Devices for the Measurement of Small Granular Samples: Evaluation of Grape Seed Protein Concentrates
(Elsevier, 2024)
Hyperspectral imaging is a well-known technique for quality control of food and agricultural products. This technique is often applied to the measurement of large and heterogeneous samples, where chemical imaging is extremely ...

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 ...

Evaluation of the influence of white grape seed extracts as copigment sources on the anthocyanin extraction from grape skins previously classified by near infrared hyperspectral tools
(Elsevier, 2017)
Hyperspectral imaging has been used to classify red grapes (Vitis vinifera L.) according to their predicted extractable total anthocyanin content (i.e. extractable total anthocyanin content determined by a hyperspectral ...

Reduction of the Number of Samples for Cost-Effective Hyperspectral Grape Quality Predictive Models
(MDPI, 2021-01)
Developing chemometric models from near-infrared (NIR) spectra requires the use of a representative calibration set of the entire population. Therefore, generally, the calibration procedure requires a large number of ...

Valorization of American Barrel-Shoot Wastes: Effect of Post Fermentative Addition and Readdition on Phenolic Composition and Chromatic Quality of Syrah Red Wines
(MDPI, 2020)
The influence of post fermentative addition of American barrel-shoot wastes on phenolic composition and chromatic quality of Syrah red wines has been evaluated as an environmentally sustainable alternative to the conventional ...

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 ...

Comparative Study on the Use of Three Different Near Infrared Spectroscopy Recording Methodologies for Varietal Discrimination of Walnuts
(Elsevier, 2020)
Walnut fruit (Juglans regia L.) is an internationally well-known product with an important tradition of consumption. Its health benefits and economic importance in the food industry make this nut an interesting research ...
Artículo
On the Use of Vibrational Spectroscopy and Scanning Electron Microscopy to Study Phenolic Extractability of Cooperage Byproducts in Wine
(Springer Nature, 2019)
Wood is an important source of phenolic compounds, which can be transferred to wine during aging process, improving its properties, from an organoleptic point of view. Therefore, understanding and optimizing the extractability ...
