Question

Protein content in soybean is ______

• A. 30%
• B. 40-45%
• C. 60%
• D. 55%

Hint:

Soybean = King of plant proteins (40-45%). Compare with other legumes: Gram (20-25%), Pea (20-25%), Lentil (25-28%).

Answer 1

The Correct Option is B

Step 1: Understanding the Question
The question asks for the approximate percentage of protein found in soybeans.
Step 2: Detailed Explanation
Soybean is a legume that is exceptionally rich in protein, making it a staple in many vegetarian and vegan diets, as well as a key ingredient in animal feed.

The protein content of whole, dry soybeans typically ranges from 38\% to 45\%. This is significantly higher than most other beans and legumes.

The option (B) 40-45\% accurately represents this scientifically established range.

Other options are incorrect: 30\% is too low, while 55\% and 60\% are too high for unprocessed soybeans (such high concentrations are only found in processed soy protein isolates).

Step 3: Final Answer
The protein content in soybean is in the range of 40-45\%.
