Among the various parameters, which affect acrylamide formation, the inhibitory e...
متن کاملAntioxidant Activity, Antiproliferation of Colon Cancer Cells, and Chemical Composition of Grape Pomace
Chardonnay and Tinta Cao grape pomaces were generated by the winemaking process. The pomaces were extracted with 50% acetone and tested for antioxidant capacities using the oxygen radical absorbance capacity (ORAC) assay, 50 EC , and ABTS •+ scavenging capacity tests. Cytotoxicity and antiproliferative activities against Caco-2 and HT-29 human colon cancer cell lines were also analyzed. The qua...
