The purple and blue grain of barley have anthocyanins that is good sources of antioxidant. Thus we investigated the malt and wort characteristic of purple and blue barley for brewing. During steeping period, anthocyanins content reduced both materials. However the lost content was different from 80% and 20% in purple and blue barley, respectively. Also the anyhocyanin content was different both malt comparing to raw grain from 0.4~4.2% in purple but 50% in blue grain.
The wort and beer color(EBC unit) and content of polyphenol and soluble nitrogen from malt of purple and blue were higher than control malt(Hopum). There was no anthocyanins in wort and beer of malt in purple and blue. In these results, it was identified that the anthocyanins from raw grain lost during malting and brewing processing with conventional method.
