Question

Polished rice has less protein due to

• A. Removal of aleurone layer
• B. Denaturation of protein by polish
• C. Heat treatment that causes destruction of proteins
• D. Both $B$ and $C$

Answer 1

The correct option is A Removal of aleurone layer

• Polished rice has the less protein content because of the removal of the aleurone layer indirectly.
• The milled rice is produced by polishing to remove residual bran on the surface is smoother and they will be polished and remove aleurone layer and this result grain containing less protein result.
• Aleurone layer is the outermost layer of the endosperm. It is a protein found in protein granules of maturing seeds and tubers, so it will be removed protein contain indirectly at time of aleurone layer has been removed.

So the correct option is A
