Question

Pulse which is most difficult to dehusk is:

• A. Lentil
• B. Bengal gram
• C. Pea
• D. Arhar

Hint:

To mill Arhar effectively, it is often sun-dried for several days after oil application to ensure the gummy layer becomes brittle enough to break.

Answer 1

The Correct Option is D

Concept: The ease of dehusking a pulse depends on the strength of the bond between the seed coat (husk) and the cotyledon.

• Some pulses have a loose bond and are "easy-to-mill."

• Others have a very strong, gummy bond and are "difficult-to-mill."

• Arhar (Pigeon pea) falls into the latter category.

Step 1: Analyzing the seed structure.
In Arhar, there is a thick layer of gummy substance between the husk and the cotyledons. This mucilaginous layer acts as a strong adhesive.

Step 2: Comparing with other pulses.
Bengal gram and Lentils have a relatively weaker bond. They can often be dehashed with simple mechanical action.

Step 3: Identifying the processing requirement.
Because of the gummy bond, Arhar requires extensive pre-treatments like oil and water application. Therefore, it is considered the most difficult pulse to dehusk. Final Answer: (D)
