Individual cultivars showed trends for total phenolic content similar to those for antioxidant activity (Table 1), with Bluegold, Legacy, Nelson, and MSU-58 demonstrating total phenolic content that was 13-23% higher at 3 weeks postharvest than at harvest, but these increases were not significant. The changes in anthocyanin content values over the postharvest period were also similar in trend to those for antioxidant activity for individual cultivars; however, none of the changes in anthocyanin content in the first postharvest interval were significant.
