The Thai fruit known as the “king of fruits” with a strong odor is the durian.
Durian is the edible fruit of trees in the genus Durio, especially Durio zibethinus, the species most widely sold internationally. Its large, thorn-covered rind protects creamy yellow or pale-orange flesh with a rich, custard-like texture. The name comes from the Malay word duri, meaning “thorn.”
Its reputation comes from a powerful aroma that divides opinion: some people describe it as sweet and complex, while others compare it to onions, sulfur, or spoiled food. The smell comes from a mixture of volatile compounds, including esters, ketones, and organosulfur chemicals. Because the odor can linger, durians are banned in some hotels and public transport systems in Southeast Asia.
Thailand grows many named varieties, including Monthong, Chanee, and Kan Yao. Monthong is especially popular because its flesh is thick, sweet, and relatively mild-smelling. Jackfruit is a common mix-up, but it has a milder fruity aroma and a different, less thorny rind.
