Abstract:

A rapid and simple method was developed for extracting malt-derived foam-active protein, and the foam-active protein was analyzed and quantified by means of Bradford method and SDS-PAGE. Four barley cultivars grown in different geographic regions were analyzed by these procedures. Based on the analysis results, the qualities of malt and beer foam were predicted. The prediction results accord with actual situation.

Key words: barley (Hordeum vulgare L), foam-active protein, beer quality
