General description

Gluten forms the chief storage protein fraction in a mature wheat grain. Gluten proteins can be divided into three main groups: high molecular weight glutenin subunits (HMW-GS), low molecular weight glutenin subunits (LMW-GS), and gliadins. Gluten has a great impact on the quality of a whole range of cereal-based foods.
Gluten, a cohesive, visco-elastic proteinaceous material, is produced as a by-product of the isolation of starch from wheat flour. It is generally supplied in a dried state called vital wheat gluten.

Application

Gluten from wheat has been used:
  • as a source of the total gluten protein to produce a gluten film to assess its viscoelastic properties at the mesostructure level
  • to study its effect on metabolic homeostasis in a murine model of diet-induced obesity
  • as a nitrogen source in gluten agar/gliadin agar (Glu-A/Gli-A) medium for gluten and gliadin hydrolysis assays

Biochem/physiol Actions

Gluten exhibits visco-elastic properties, which helps in preparing synthetic cheese with the texture and eating quality of natural cheese. It helps in fortifying low-protein bread flours. Gluten is majorly used in non-bakery foods as a meat replacement in vegetarian foods. It is also used in the production of seafood and crab analogs. Vital wheat gluten has a unique visco-elastic property that enhances dough strength, mixing tolerance, and handling properties.

Modifications of mechanical properties of wheat dough during thermal treatments depend mainly on the capacity of wheat gluten proteins to establish intra- and intermolecular interactions when subjected to high-temperature processing. The present study investigates the effect of thermal treatments on
