The Science of Stink: Why Does Durian Smell So Strong?

Ever wondered why durian smells so strong? Discover the science behind durian’s infamous odor and why it’s loved (or hated) in Singapore.

Durian, Singapore’s beloved "King of Fruits," is famous for its unique taste and divisive smell. While some can’t get enough of its creamy texture and rich flavor, others are repelled by its pungent aroma. But what exactly makes durian smell so strong? Let’s dive into the science behind durian’s infamous stink and uncover why it’s such a polarizing fruit.

The Chemistry of Durian’s Smell
Scientists have identified over 50 chemical compounds in durian that contribute to its distinctive odor. These include:

Sulfur compounds: Responsible for the rotten egg-like smell.

Esters and alcohols: Add fruity and sweet notes.

Aldehydes: Contribute to the sharp, pungent aroma.

The combination of these compounds creates a complex scent that can be described as sweet, savory, and rotten all at once. Interestingly, the smell is so potent that durian is banned in many public spaces, including Singapore’s MRT and buses.

Why Do People Love or Hate Durian?
The reaction to durian’s smell is deeply personal and often cultural. In Singapore, durian is a delicacy enjoyed by many, but its strong odor can be overwhelming for first-timers. Research suggests that genetics may play a role in how people perceive durian’s smell, with some individuals more sensitive to sulfur compounds than others.

Fun Fact: Did you know that durian’s smell is so strong that it can linger for hours? This is why durian lovers often eat it outdoors or in well-ventilated areas.


Whether you love it or hate it, there’s no denying that durian’s smell is one of a kind. The next time you enjoy a slice of Mao Shan Wang or D24, you’ll have a deeper appreciation for the science behind its unforgettable aroma.
