The role of grape berry skin as a protective barrier against damage by physical injuries and pathogen attacks requires a metabolism able to sustain biosynthetic activities such as those relating to secondary compounds (i.e., flavonoids). In order to draw the attention on these biochemical processes, a proteomic and metabolomic comparative analysis was performed among Riesling Italico, Pinot Gri...

Abstract This study had as a goal to carry out the drying of red grape pomace (RGP) using 2 × 3 factorial design. The design experiment included combinations time and temperature in order achieve lowest possible moisture levels examine losses precious polyphenols, but also effect on antioxidant properties RGP extracts. Drying for 6 hrs at 80°C (D6/80) provided with satisfactory level (11%). A c...

Colon cancer is very common, but those who consume anthocyanins, common red pigments in wine, grapes and other fruits, appear to have lower rates of colon cancer. We investigated the fate of grape anthocyanins in the colon by using a pig model of the lower intestine and observed the rapid conversion to three simple phenols. These were studied, along with metabolites reported by others, for thei...
