Maize germ recovered during dry milling is processed chiefly for

  • A.Starch
  • B.Pectin
  • C.Silica
  • D.Maize oil

Answer: D

Correct answer: Maize oil

Maize germ is unusually large, around 10 to 12 per cent of the kernel, and roughly a third oil. Degermination in dry milling recovers it as an intact fraction, and it is pressed or solvent-extracted for maize oil, leaving a protein-rich cake for feed.

Removing the germ serves the main product as well: its oil would otherwise turn rancid and ruin the shelf life of the grits and meal. The starch stays with the endosperm, and neither pectin nor silica is present in any useful quantity.
