Characteristic of the nutritive value of the protein from rye coryopses. II. Evaluation of rye grain protein quality by Dye-Binding Capacity method

Abstract

The usefulness for breeding porposes of the azosulphonic dye-binding capacity (DBC method) by proteins for large scale screening nutritive value characteristic of rye grain protein was studied. It was established that binding capacity of dye by rye grain protein is positively, significantly correlated with protein nutritive value indicators, e.g. CS (Chemical Score). The amounts of the binded dye by 1 g of milled rye grains were positively, significantly correlated with "useful" protein content of grains. DBC plus Kjeldahl protein evaluations are together suitable for mass screening quantitative and qualitative characteristic of rye grain protein.
