Statement I: Raising the extraction rate darkens the flour.
Statement II: Higher extraction brings more bran and aleurone into the flour.
In the light of the above statements, choose the correct answer.
Answer: D
Correct answer: Both Statement I and Statement II are correct
Both statements are correct and the second explains the first. Raising the extraction rate means taking flour from further out in the kernel, so material from the aleurone layer and the inner bran passes into the flour.
Those layers are pigmented and mineral-rich, so the flour darkens and its ash content rises together - which is precisely why ash is used as the trading index of extraction. The trade-off runs the other way nutritionally: higher extraction retains more of the fibre, minerals and B vitamins that low-extraction white flour discards.
