Question

The instrument used to measure plasticity of bread dough is known as

• A. Penetrometer
• B. Fibrograph meter
• C. Tenderometer
• D. Brabender Farinograph

Hint:

Associate key instruments with their function in cereal science:
\textbf{Farinograph:} Dough behavior during mixing.
\textbf{Extensograph:} Dough resistance to stretching and elasticity.
\textbf{Alveograph:} Dough tenacity, extensibility, and baking strength by inflating a dough bubble.

Answer 1

The Correct Option is D

Step 1: Concept Overview:
Dough rheology refers to the physical properties of bread dough, including plasticity, elasticity, and resistance to extension. Instruments are used to quantify these properties to predict dough behavior during processing and the final bread quality.
Step 3: Instrument Details:
- Brabender Farinograph: This instrument, standard in the baking industry, assesses dough's physical properties by measuring its resistance to mixing blades. The Farinogram provides data on water absorption, dough development time, stability, and mixing tolerance, all related to dough plasticity and elasticity.
- Penetrometer: Measures the hardness/consistency of substances like fats and gels by assessing cone/needle penetration depth under a specific weight.
- Fibrograph meter: Used in textiles to determine cotton fiber length and uniformity.
- Tenderometer: Measures food tenderness, especially in peas, by determining the force needed to crush a sample.
Step 4: Conclusion:
The Brabender Farinograph is specifically designed to measure the rheological properties of bread dough, including plasticity, during mixing. Thus, option (D) is the correct answer.
