Preparation and properties of wheat gluten/silica composites

摘要

Wheat gluten (WG)/silica (SiO2) hybrids were prepared through in-situ synthesis of SiO2 in WG disper-sion of aqueous ammonia. The hybrids with different SiO2 contents were mixed with glycerol plasticizer to form cohesive dough and the dough was compressively molded to form cross-linked sheets. Morphology, moisture absorption, protein solubility in water, tensile mechanical properties and dynamic rheological behavior of the WG/SiO2 composites were investigated in relation to SiO2 contents.
