Where does the origin of the durian unique come from?

The smell of rotten eggs H ₂ S, onion scent, rotten onions, honey, caramel, fresh fruit, . together form an extremely special scent of durian. That is the conclusion of the scientists after analyzing durian's chemical composition to explain why it has a unique taste that hates and lovers.

Where does the scent of durian come from?

Durian is not only a unique fruit with a thorny crust but it also has an extremely characteristic flavor that many people hate it, disgusting it, and others like it. Even people who like to eat admit that it smells very strong and sometimes they don't eat it in public places to avoid affecting others.

Durian smell very characteristic.

Of course, scientists also pay attention to this and after the research process, they discovered a rich aroma of durian and from there, explained the source of discomfort when smelling it. Analysis was conducted using solvent extraction technique . This technique will mix the liquid containing the components to be analyzed with another liquid, then put this mixture on the shaker to separate.

The above method will help extract and isolate each chemical component in the original mixture. The problem here is that you need to know which liquid to use. First, the two liquids must not dissolve into each other, such as oil and water. Second, if temporarily called A is the liquid to be analyzed, B is the added liquid, then B needs to have the solubility of the chemicals in A higher than the solubility of A. This helps the components in A dissolve into B to facilitate multiple extraction.

The process is repeated many times, it is very time consuming and requires guesswork. After applying this technique to durian, the scientists identified very difficult smelling substances for humans, such as: hydrogen sulfide (H ₂ S - the characteristic rotten egg smell) and methanethiol ( CH ₃ SH) , . At the same time, they also found some 'good' smells like onions, sweets, .

The smell of durian is a mixture of many odors.

In particular, durian 'sweet chemicals' include: ethyl cinnamate (smelling like honey) , 4-Hydroxy-2,5-dimethyl- 3 (2H) -furanone (Furaneol - smell of caramel) and acetaldehyde smells like fruit. At the same time, durian also has 1- (ethylsulfanyl) ethanethiol for odor like roasted onions , 1- (ethyldisulfanyl) -1- (ethylsulfanyl) ethane gives the strong odor of onion and ethanethiol for rotten onions.

In durian also contains many other compounds: some smells like soup spices, others for fruity. Finally, the scientists concluded that durian has the smell of a smell of fresh fruits and vegetables. The problem is that it tries to show both of those smells at the same time and leads to the extremely unique taste of durian that people love, others are disgusted away.
