Subtopic: Processing of seeds, spices, fruits and vegetables
Question Statement:
Processing of Agriculture Produce: Processing of seeds, spices, fruits and vegetables; value addition of agriculture produce.
The clean paddy production per annum is 160 million tonnes. Average milling quality analysis indicates husk content, total yield, and degree of polish as 22%, 73.32%, and 6% respectively. For average bran oil yield of 20%, the annual rice bran oil potential (million tonnes) is
Options:
(A) 1.268
(B) 1.498
(C) 1.617
(D) 1.945
Official Answer Key:
B
Step-by-Step Solution & Explanation
Brown rice (paddy minus husk) = 100% − 22% = 78% of paddy.
Bran fraction = Brown rice % − Total (polished) rice yield % = 78% − 73.32% = 4.68% of paddy (this is the bran layer removed during polishing).
Bran produced = 160 × 0.0468 = 7.488 million tonnes.
Bran oil potential = Bran × oil yield = 7.488 × 0.20 = 1.4976 ≈ 1.498 million tonnes. Answer: (B) 1.498.
