Assertion (A): Dehulling is unnecessary when the seed is to be solvent extracted.
Reason (R): Hulls carry almost no oil but occupy extractor volume and absorb oil during processing.
Select the correct answer from the options below.
Answer: D
Correct answer: A is false but R is true
The reason is correct and it refutes the assertion. Hulls carry almost no oil, so they dilute the feed; they occupy extractor volume that could hold oil-bearing material; and being absorbent, they retain oil during processing and carry it out in the meal.
Every one of those is an argument for dehulling before solvent extraction, not against it. Dehulling also raises the protein content of the meal, which is worth money in its own right. The assertion states the opposite of what the reason establishes.
