Subtopic: Biochemical changes during paddy parboiling
Question Statement:
A $1000\text{ kg}$ batch of paddy is milled. After cleaning, dehulling, and polishing, the output yields $700\text{ kg}$ total milled rice, of which $560\text{ kg}$ consists of whole grains (head rice). The Head Rice Yield (HRY, in percent) of the paddy is:
Answer Key:
56.0
Step-by-Step Solution & Explanation
Head Rice Yield:
$\text{HRY} = \frac{\text{Weight of whole milled head rice}}{\text{Total weight of rough paddy}} \times 100 = \frac{560}{1000} \times 100 = 56.0\%$
