Question

The process of parboiling is used for
A. Paddy
B. Millets
C. Oil seeds
D. Pulses
E. Sprouts
Choose the correct answer from the options given below:

• A. A only
• B. A and B only
• C. C and E only
• D. A and D only

Hint:

Parboiling is always associated with rice (paddy) processing. It is the single most effective method used to reduce grain breakage during milling.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Parboiling is a hydrothermal pre-treatment process applied to grains before milling.
It involves three main steps: soaking (hydration), steaming (gelatinization of starch), and drying.

Step 2: Detailed Explanation:
Let us analyze the application and benefits of parboiling:
- Target Grain: Parboiling is used almost exclusively for Paddy (unhusked rice) (A).
- Key Effects of Parboiling Paddy:
1. The hot water soaking and steaming gelatinizes the starch granules in the endosperm, closing any internal cracks in the grain.
2. This process hardens the kernel, which reduces the percentage of broken grains during milling and increases the total recovery of head rice.
3. Water-soluble vitamins and minerals (such as B-complex vitamins) migrate from the bran layer into the starch endosperm, making parboiled rice more nutritious than raw milled rice.
4. It inactivates enzymes, preventing rancidity and improving storage stability.
- Parboiling is not standardly used for other crops like millets, oil seeds, pulses, or sprouts.
Therefore, only option A is correct.

Step 3: Final Answer:
The correct option is (A).
