Modification of the structural and functional properties

The modification of the structure and function of wheat gluten because of planetary ball milling was investigated. Reduced SDS-PAGE revealed that the subunit compositions and bands of gluten did not change with an increase in grinding time. FTIR analysis showed that α-helices and β-sheets decreased
