Question

Tempering degerming is a method of

• A. Rice milling
• B. Corn milling
• C. Wheat milling
• D. Pulse milling

Hint:

Corn dry milling $\rightarrow$ Tempering Degerming (Beall degermer).
Wheat milling $\rightarrow$ Break & Reduction rolls.
Rice milling $\rightarrow$ Dehusking & Polishing.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Dry milling of corn (maize) utilizes hydrothermal tempering to equilibrate kernel moisture and facilitate mechanical separation of germ, endosperm, and pericarp.

Step 2: Detailed Explanation:
The Tempering-Degerming (TD) process is the standard commercial dry milling technique for maize (corn).
It involves:
1. Conditioning/tempering cleaned whole corn kernels with water or steam to reach \(20\text{--}24\%\) moisture content, which selectively toughens the rubbery oil-rich germ and pericarp while keeping the starchy endosperm friable.
2. Passing through a Beall degermer to detach and recover the intact germ and bran from the large hominy corn grits.

Step 3: Final Answer:
Thus, tempering degerming is a method of Corn milling, matching option (B).
