Preliminary study to determine the phenolic maturity stage of grape seeds by computer vision
(Elsevier, 2012-06-30)
The applications of computer vision technology for acquiring and analysing images have been extended to the quality evaluation in food industry. This technique involves great advantages for the objective, rapid, non-contact ...

Assessment of the differences in the phenolic composition and color characteristics of new strawberry (Fragaria x ananassa Duch.) cultivars by HPLC–MS and Imaging Tristimulus Colorimetry
(Elsevier, 2015)
The phenolic composition (by HPLC-DAD-MS) and color characteristics (by Imaging Tristimulus Colorimetry) of four strawberry cultivars that have shown good climate adaptation to subtropical area (Nikte, Zamorana, Jacona and ...

Impact of a post-fermentative maceration with overripe seeds on the color stability of red wines
(Elsevier Ltd, 2019-01-30)
With the purpose of modulating the copigmentation equilibria of red wines, an environmentally sustainable process was performed based on post-fermentative addition of overripe seeds (OS). Simple (SW) and double (DW) addition ...

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 ...

A novel and enhanced approach for the assessment of the total carotenoid content of foods based on multipoint spectroscopic measurements
(Elsevier, 2011-06-15)
We have devised a more sensible approach to estimate the carotenoid content of orange juices, which can be regarded as a model system of food with intricate carotenoid pattern. For this purpose spectroscopic information ...

Measurement of Ripening of Raspberries (Rubus idaeus L) by Near Infrared and Colorimetric Imaging Techniques
(Springer Nature, 2017)
This work includes the evaluation of 168 samples of raspberries ‘Glen Lyon’, representing whole maturation period, by colorimetric and near infrared imaging techniques, as well as the quantification of total phenols, total ...

Colorimetric characteristics of the phenolic fractions obtained from Tempranillo and Graciano wines through the use of different instrumental techniques
(Elsevier, 2012-06-30)
The aim of the present work was to determine whether there is any relationship between measurement by transmission and reflection (in the latter case, with and without contact with the sample). We also evaluated which ...

Effect of Addition of Overripe Seeds from White Grape by-products During Red Wine Fermentation on Wine Colour and Phenolic Composition
(Elsevier, 2017)
The effect of the fermentative addition of overripe seeds by-product (Pedro Ximénez white grapes, 3 g/L) on the phenolic composition and colour of red wines was studied by rapid resolution liquid chromatography (RRLC-MS) ...

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 ...
