Considering how popular grapes are in terms of their antioxidant benefits, we compared concord, purple, red, and green grapes for total antioxidant capacity (TAC) and carbohydrate concentration. All grapes were acquired from commercial sources and samples of each were separated into skinned and not skinned groups. Each whole grape and the skins were individually homogenized and then separated i...

Fourier-transform near infrared (FT-NIR) reflection spectra of intact berries the grape variety Thompson seedless were used to predict total soluble solids (TSS) content. From an initial dataset, 12 subsets considered by applying variable selection extract reflectance values at wavenumbers most correlated chemometrically measured TSS The datasets processed both multiple linear regression (MLR) ...

Grapes are one of the important fruit crop in the world, with production rates of approx. 50 million tons per year (Schieber et al., 2001). Grapes can be decay during pre harvest and post harvest and post harvest decay of grapes can be due to physical, physiological, or pathological factors. Rachis dehydration is a main decay factor (physical deterioration) of grapes during the pre or postharve...

Two modern laser-based techniques were synchronously applied to study the dynamics of the trans-resveratrol activity in Botrytis cinerea-infected grapes. Direct analysis of trans-resveratrol in both infected and noninfected grapes (Vitis vinifera, Aledo variety) was performed by using an analytical technique incorporating laser desorption coupled with laser resonant ionization and time-of-fligh...
