Statement I: Dry basis moisture content can exceed one hundred per cent.

Statement II: The dry basis denominator is the mass of dry matter alone.

In the light of the above statements, choose the correct answer.

  • A.Both Statement I and Statement II are incorrect
  • B.Statement I is correct but Statement II is incorrect
  • C.Statement I is incorrect but Statement II is correct
  • D.Both Statement I and Statement II are correct

Answer: D

Correct answer: Both Statement I and Statement II are correct

Both are true, and again the second explains the first. Since the dry basis denominator is the dry matter alone, a sample holding more water than dry matter gives a ratio above one.

Fresh fruits and vegetables routinely do: a tomato at 95 per cent wet basis is \( 95/5 = 1900 \) per cent on the dry basis. The wet basis has no such freedom, being bounded at 100 per cent because its denominator includes the water. This is one reason the dry basis is preferred for high-moisture materials, where small wet basis differences correspond to large changes in the water actually present.
