Question:
Which from following statements is NOT correct regarding tannins?
Which from following statements is NOT correct regarding tannins?
Show Hint
Browning is enzymatic oxidation; it can be prevented by antioxidants or acidity (like lemon juice), not by the tannins themselves.

- These avoid browning of freshly cut potato.
- These are formed from polyphenols.
- These are obtained by polymerisation of quinones.
- These are generated after cutting fruits or vegetables.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Tannins are phenolic compounds found in plants.
Step 2: Analysis
- Browning in potatoes/fruits is caused by the oxidation of phenols into quinones, which then polymerize to form tannins (brown pigments). - Thus, tannins are the result of browning, not the agent that avoids it.
Step 3: Conclusion
Statement (A) is incorrect because tannins are the product of the browning process.
Final Answer: (A)
