Relationship of the functional properties of dry wheat gluten with amino acid composition and its quality indicators

The aim of the work was to study the dependence of the functional properties of dry wheat gluten (DWG) on the quality indicators obtained after regeneration of its raw form, and amino acid composition. Given that the main direction of use of DWG is the production of flour and bread, the data on the relationship are necessary to predict and increase its use in the production of confectionery, sausage products and other food products. We used 19 samples of the DWG produced by «BM» (Kazakhstan), 3 samples obtained from strong, weak, and average wheat grain quality, and methods for determining the yield and compression deformation (elasticity), the hydration ability of the regenerated raw SPK, amino acid and fractional composition. It is established that the functional properties of the DWG can be predicted on the basis of hydration and compression deformation (elasticity). The DWG with the hydration of 190-200% had the highest foaming capacity, and the most fat emulsifying ability with values of 140-150%...
