Which compound is responsible for the banana and pear smell?

• A. Isoamyl acetate
• B. Acetaldehyde
• C. Ethyl acetate
• D. Octanal

Answer: (A)

Fruity aromas in ripe fruits are usually esters, formed when an alcohol reacts with an acid to create a volatile compound with a characteristic scent. Isoamyl acetate is the classic banana odor, giving that unmistakable banana smell people recognize in flavorings and ripe fruit. It’s produced naturally in fruit and is widely used to mimic bananas in foods and perfumes. The pear note also comes from ester chemistry, but the standout aroma that most people associate with bananas is isoamyl acetate. Acetaldehyde has a sharp, green-apple-like odor that’s quite different from banana. Ethyl acetate does have a fruity smell, but it’s not the signature banana scent. Octanal carries a citrusy, waxy aroma rather than a banana note. So isoamyl acetate best explains the banana (and related pear notes) smell.
