Interrelation of Functional Properties of Protein Products from Wheat with the Composition and Physicochemical Characteristics of Their Proteins

The results of studies of the correlation relationship between the functional properties of dry wheat gluten, protein concentrates from wheat bran and their granulometric fractions with the features of the chemical composition, and the physicochemical properties of their proteins are presented. Granulometric fractions of bran were obtained from grinding process systems with different particle sizes. The correlation interrelation between the functional properties of protein products (solubility, water binding capacity, fat-binding capacity, and foaming capacity) with a mass fraction of components, fractional amino acid composition, the number of thiol metabolism groups (–S-S– and –SH) and the aggregation capacity of whole gluten proteins, its fractions (gliadin, glutenin) and products from wheat bran. The obtained information is expedient for using when modifying the properties of wheat protein products with the purpose of expanding the directions of their use
