Question:
The characteristic aromatic compound of coconut is -
The characteristic aromatic compound of coconut is -
Show Hint
Lactones are organic cyclic esters formed by intramolecular condensation of hydroxy acids.
They are responsible for the dominant, characteristic aromas of many fruits (such as \(\gamma\)-decalactone in peaches).

- \(\gamma\)-Naralactone
- \(\gamma\)-Nonalactone
- \(\gamma\)-Methyl isolactone
- \(\gamma\)-Propyl isolactone
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
The distinct sensory flavor and aroma profiles of fruits and nuts are governed by specific volatile organic compounds, such as esters, aldehydes, ketones, and lactones.
Step 2: Detailed Explanation:
- The characteristic, highly distinct sweet, coconut-like aroma is caused by \(\gamma\)-nonalactone (also commonly referred to in the flavor industry as "coconut aldehyde" or \(\gamma\)-amylbutyrolactone).
- It is a cyclic ester (lactone) widely used as a flavoring agent in foods and cosmetics to impart a realistic coconut profile.
- Option (A) "\(\gamma\)-Naralactone" is a typographical spelling error.
Step 3: Final Answer:
The characteristic compound is \(\gamma\)-nonalactone, which corresponds to option (B).
