Which statement about the aleurone layer is TRUE?

  • A.It is the oil-rich embryo
  • B.It is the outermost layer of the grain
  • C.It is mineral-rich and leaves with the bran
  • D.It becomes the bulk of the flour

Answer: C

Correct answer: It is mineral-rich and leaves with the bran

The aleurone is a single layer of cells lying just inside the seed coat and forming the outermost part of the endosperm botanically, though it is removed with the bran in milling. It is rich in protein, minerals and vitamins, and being mineral-rich it is the principal contributor to the ash figure by which flour is graded.
