Colored grains are rich sources of anthocyanins that could play an important role in the prevention of various diseases associated with oxidative
stress. Bearing in mind that cereals are widely grown crops, anthocyanins-rich colored grains could be used as a functional food ingredient that
provides health benefi ts to a large part of human world’s population. This study investigated composition and content of anthocyanins in the grain
of blue popping maize, deep purple maize, purple wheat, and black soybean. The relationship of acylated and non-acylated forms before and after
alkaline hydrolysis of anthocyanin extracts has been studied as well. Deep purple maize had the highest content of total anthocyanins reaching as
much as 4988.90 mg CGE/kg d.m. Ten anthocyanins were identifi ed in blue popping maize, of which two are isomers of cyanidin-3-(malonylglucoside)
and three of cyanidin-3-(dimalonyl-β-glucoside). Seven, nine, and three anthocyanins have been identifi ed in the deep ...purple maize, purple wheat,
and black soybean, respectively. Cyanidin derivatives were predominant and their acylated forms accounted for about 98, 29, 71, and 0% of the total
anthocyanins content in the grains, respectively. According to the study, acylated derivatives were completely degraded under the effect of highly alkaline
pH. However, at the beginning of their degradation they were transformed to their non-acylated parents.
The results could be useful to better understanding of the nature of anthocyanin in colored grains and, in that regard, their use for the derivation
of food products with functional potential, as well as of natural dyes and pharmaceutical ingredients.
