Views on the Amino Acid Composition of Grain and the Influence of Processing

There are no differences in the amino acid composition between mineral or biological fertilized wheat and rye. The amount of fertilizing and the different locations are without influence on the distribution of amino acids in triticale varieties and breeding lines, because of their genetic background. Protein fractions of wheat are very different in amino acid composition. Gliadin and glutenin contain relatively high amounts of proline and glutamic acids, lysine and methionine are very low, the globulin fraction is rich in glycine and arginine. A very similar distribution and amino acid composition of these fractions are examined after dough formation, except a remarkable reduction of proline in the glutenin fraction.
