Head rice yield refers to

  • A.The total milled rice from paddy
  • B.The proportion of husk removed
  • C.The degree of whitening achieved
  • D.The proportion of whole kernels

Answer: D

Correct answer: The proportion of whole kernels

Head rice yield is the proportion of the paddy that emerges as whole, unbroken kernels, and it is the measure that determines a mill's revenue. Whole grains command a substantially higher price than brokens - often nearly double - so a few points of head rice yield are worth far more than the same quantity of total output.

Total milled rice from paddy is a different figure, the milling yield, and it includes brokens. Degree of milling describes how much bran has been removed, and husk removal is what hulling achieves.
