In the protein of barley, the contents of Glu, Pro, Phe, Arg are high, and the Limitation amino acids are Met and Trp. The content of Lys in barley is higher than that in wheat, which showed it had a good nutrition quality. The reason for barley protein unforms gluten net tissue was the content less of prolamine and glutein in the protein of barley. The one of main factors for barley showing high biological activity functions might lie in its high β-glucan and polyphenol chemical compound content.
