Question

What is the approximately average protein content (on dry weight basis ) in potato ?

• A. 5 %
• B. 10 %
• C. 15 %
• D. 20 %

Hint:

Potato composition:
Fresh weight: Mostly water (70-80%), carbohydrates (starch), and about 1-2% protein.
Dry weight: When water is removed, the percentage of other components increases. Protein content on a dry weight basis is typically around 8-12%, averaging near 10%.

Answer 1

The Correct Option is B

Step 1: Potato is about 75-80% water, so fresh weight is roughly 1-2% protein.
Step 2: Removing the water on a dry-weight basis concentrates this to roughly 8-12%.
Step 3: The commonly cited average figure is approximately 10%.
Step 4: The correct answer is 10%.
