Concept:
In food science, especially in bakery technology, various instruments are used to measure dough properties such as elasticity, extensibility, and plasticity.
Step 1: Understanding dough plasticity.
Plasticity refers to the ability of dough to undergo deformation without breaking, which is crucial for bread-making quality.
Step 2: Role of Extensograph.
The Extensograph measures the extensibility and resistance of dough when stretched, which directly reflects its plasticity and handling properties.
Step 3: Functions of other instruments.
- Farinograph: Measures water absorption and dough mixing properties
- Amylograph: Measures starch gelatinization and enzyme activity
- Viscometer: Measures viscosity of fluids
Step 4: Conclusion.
Thus, the Extensograph is primarily used to determine the plasticity of bread dough.
