www.ars.usda.govACN identification in all of the foods has been reported in our previous papers (26, 27). Quantification of anthocyanins followed the procedure reported previously (32). The intra- and interassay CVs were 1.5 and 2.5%, respectively. The limit of quantification for ACNs under current experimental conditions was 10 ng. Calculations were made

This symptom can be particularly difficult to diagnose because cool temperatures, disease, drought, and even maturation of some plants can also cause anthocyanin to accumulate (Bennett, 1994). Certain plant cultivars
