In recent years, climate change has strongly influenced viticulture, with a higher concentration of sugars in grapes, a lower concentration of organic acids and, therefore, increases in alcohol concentration and pH. This work aimed to increase the concentration of organic acids and total acidity in...

The green colour indicates control plants, while the red colour refers to the nitrogen-deficient plants. Indices were calculated based on reflectance (ρ), transmittance (τ) or combination of ρ with τ (i.e., ρ + +τ). Spectra were acquired by using the hyperspectral absorption reflectance...
change the protein profiles. The DEPs were not identified as new unintended proteins, toxins or allergens, showing only changes in abundance. Functional classification showed that these DEPs were mainly involved in catalytic activity and binding. Pathway annotation showed that these DEPs mainly ...
(vide infra) were measured several times at different positions on the sample, and the average of the coordinates L*a*b* was calculated. The change in colour of each sample was then calculated as the difference (Δ) between the L*a*b* results for the non-treated and for the treated ...

this results into chemical transformation of curcuminoids along with change in its natural bright yellowish orange colour, which may not be desired for application in nutraceutical and food industry. Further the coating of curcuminoids by polymers for colour masking depends on percentage of coating appli...
The composition can contain other hydrophilic active principles, such as proteins or protein hydrolysates, amino acids, polyols, urea, allantoin, sugars and sugar derivatives, water-soluble vitamins, plant extracts and hydroxy acids. Use may be made, as lipophilic active principles, of retinol (vit...
“Triggering condition” as used herein in one example means anything, as an act or event, that serves as a stimulus and initiates or precipitates a change in the filament, such as a loss or altering of the filament's physical structure and/or a release of an additive, such as an active...
