Discussion
Match each rice milling operation in List I with what it removes in List II.
List I
A. Hulling
B. Whitening
C. Polishing
D. Grading
List II
1. Bran layers and germ
2. Husk
3. Broken kernels from whole
4. Last traces of bran, adding gloss
Select the correct match.
Answer: C
Correct answer: A-2, B-1, C-4, D-3
The four operations run in sequence and each removes something different. Hulling takes off the husk, leaving brown rice. Whitening abrades away the bran layers and the germ. Polishing removes the last traces of bran and adds gloss. Grading then separates the whole kernels from the brokens, which is what determines the head rice yield.
