Feasibility Study on the Use of Near-Infrared Hyperspectral Imaging for the Screening of Anthocyanins in Intact Grapes during Ripening
(American Chemical Society, 2013)
The potential of near-infrared hyperspectral imaging to determine anthocyanins in intact grape has been evaluated. The hyperspectral images of intact grapes during ripening were recorded using a near-infrared hyperspectral ...

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 ...

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 ...

A novel method for evaluating flavanols in grape seeds by near infrared hyperspectral imaging
(Elsevier, 2014)
Chemical composition of seeds changes during grape ripening and this affects the sensory properties of wine. In order to control the features of wines, the condition of seeds is becoming an important factor for deciding ...

Implications of the Red Beet Ripening on the Colour and Betalain Composition Relationships
(Springer Nature, 2018)
The evolution during ripening of Beta vulgaris (var. Pablo) on colour and betalain composition, not previously conducted in conjunction in red beets, has been examined. According to the results, it could be asserted that ...

Proteomic and computational characterisation of 11S globulins from grape seed flour by-product and its interaction with malvidin 3-glucoside by molecular docking
(Elsevier, 2022)
Grape seed flour by-product (GSBP) is an economic and renewable source of proteins, increasingly being explored due to interesting technological application such as colour protection in rich-anthocyanins beverages. ...

Effect of salt stress in the regulation of anthocyanins and color of Hibiscus flowers by digital image analysis
(American Chemical Society, 2014-07-23)
The effect of salt stress (200 mM NaCl for 28 days) on physiological characteristics of Hibiscus rosa-sinensis, such as abscisic acid (ABA) content, electrolyte leakage, and photochemical efficiency in leaves, and its ...

Application of the differential colorimetry and polyphenolic profile to the evaluation of the chromatic quality of Tempranillo red wines elaborated in warm climate. Influence of the presence of oak wood chips during fermentation
(Elsevier, 2013-12-01)
The effect of adding American oak wood chips during fermentation on Tempranillo red wines elaborates in a warm climate has been studied. Our attention was focused on the tristimulus colorimetry, differential colorimetry ...
