Truffles grow underground in temperate forests, relying on a symbiotic relationship with large trees. Resembling tubers with a bumpy surface, they develop in subterranean circles at depths of 5-40 centimeters, close to the roots of oak and elm trees. This relationship allows for the exchange of essential nutrients between the trees and the fungi.
Finding truffles can be challenging since they grow hidden beneath the soil with no visible signs above ground. Trained animals, such as pigs and dogs, are often used to locate them.
In 2014, researchers from Chiang Mai University made an exciting discovery in Doi Suthep-Pui National Park. They identified a truffle species named Tuber thailandicum, which has a flavor profile similar to the renowned white truffles from Alba, Italy. This discovery hints at Thailand’s potential to become a future truffle supplier.
Dr. Nakarin Suwanaraj, a key member of the research team, stumbled upon these truffles near a landslide area while studying mushrooms in the park. The samples were sent for DNA analysis, confirming their identity as truffles.
Interestingly, Thai truffles do not grow near oak trees as their Western counterparts do but are found near Betula alnoides, locally known as “tiger power trees.” The research team is now working on cultivating these truffles for commercial use, although it may take some time before they become a staple in Thailand’s local ingredient repertoire.
