Question

In milling quality analysis, total yield implies…….

• A. % brown rice received from clean paddy
• B. % milled rice received from clean paddy
• C. % head rice received from clean paddy
• D. % broken rice received from clean paddy

Hint:

Total Yield = Head Rice + Brokens. In the market, Head Rice gets a high price, while Brokens are cheaper. But "Total Yield" counts both!

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the technical definition of "total yield" in the context of the rice milling industry.

Step 2: Detailed Explanation:

• Rice Milling Process: Paddy consists of the husk and the brown rice kernel. Milling involves removing the husk (dehusking) and then removing the bran layers (polishing/whitening).

• Milled Rice: This is the final "white rice" product. It consists of both whole kernels and broken kernels.

• Total Yield: In quality analysis, "Total Yield" refers to the total weight of the edible white rice (whole + brokens) obtained from a unit weight of clean paddy. It represents the efficiency of the entire milling process. Typically, total yield for rice is around 67-70%.

• Comparison with other terms:
• Head Rice Yield: Refers only to the percentage of whole or nearly whole kernels received. This is the most economically important figure.
• Brown Rice Yield: The percentage of rice obtained after only dehusking (husk removed, bran intact).

Step 3: Final Answer: Total yield is the percentage of all milled rice (including brokens) obtained from the clean starting paddy.
