Anthocyanins pigments are very effective scavengers of free radicals, which have been demonstrated in vitro through such assays as free radical-scavenging capacity Total anthocyanins index was determined using the pH differential method described by Giusti and Wrolstad The correlation of the extraction systems are shown by the Pearson coefficient 29, 30 for color coordinates, anthocyanins index and the second-order rate constants k RSC table 3.
Antocianinas – Maiz Morado
They also make a drink from the kernels which they call ”chicha morada”, which has been related by folklore to increased health benefits LC-MS analysis of anthocyanins from purple corn cob. Figure 1 shows the average spectral response corresponding to different extraction systems, observing an increase in the absorption spectrum with decreasing solvent polarity.
Antioxidants are substances that when present in foods or in the body at low concentration compared with that of oxidizable substrates, significantly delays or prevents oxidation of that substrate 1.
