Concept:
Gluten is a composite of storage proteins that provides elasticity and structure to dough.
• It is formed when two specific proteins are hydrated and kneaded.
• These components are Prolamins and Glutelins.
Step 1: Identifying the components of Gluten.
In Wheat, these proteins are called Gliadin and Glutenin.
Together, they form the viscoelastic network known as gluten.
Step 2: Analyzing other cereals.
Rice and Amaranth are considered "gluten-free" cereals.
Maize contains a protein called Zein, but it does not form a gluten network like wheat.
Step 3: Functional significance.
The presence of gluten makes wheat the only cereal suitable for making leavened bread.
It traps carbon dioxide gas, causing the bread to rise.
