What is the black truffle?

The black truffle or tuber melanosporum is an underground fungus known to be scarce, what makes it exclusive and unique. Also called Perigord truffle in France, trüffel in german or black truffle in English.

Since ancient times it has been enveloped in a halo. Towards the fourth century a. C., the Greek philosopher Theophrastus described truffles as “a mysterious subterranean fruit that appeared after storms”. From there, she became involved in mysticism and the charm of having been an ingredient in witchcraft.

The explanation of its origin was also associated with mystery. For years, they were believed to be tree roots and protrusions from biting flies.

In fact, truffles are fructifications of underground fungi. The fungi that produce mushrooms and truffles are made up of filamentous structures called hyphae. These are intertwined, forming a skein of filaments called mycelium. From there come, seasonally, the fructifications.

The difference between mushrooms and this type of fungus is that, even being born below the ground, rise to the surface when mature to disperse spores. In other words, when they come out they are already ripe.

Black truffles are fructifications. When they emerge from the ground they are ripe.


As for its structure, it has a spherical or globose body when the ground is loose or irregular. At first, they have a reddish color, but when ripe they turn black and acquire a pungent odor.

They have an outer layer of protection called peridium, which when brushing and washing shows some species of warts. When cutting it, the internal zone is observed, called glebawhich is fleshy and black.

The gleba it contains abundant white veins that are distributed throughout the meat. It is here that the spores are produced for their multiplication and development.

From a gastronomic perspective, it is known as the underground empress or the kitchen diamond They give a characteristic smell and flavor to each dish.


Its distribution in the world is not well studied. Only 30% of the earth’s surface has been surveyed for truffle harvesting. However, so far it has been determined that their underground way of life is an adaptive strategy to the economy of water.

It is characteristic of semi-arid environments, where most of these fungi have been found. Therefore, there is a great shortage of truffles in the tropics.

As it grows?

The fungus grows in a strategic way, adapting to the environment in the following way: the truffle needs water, so makes a symbiotic relationship with trees and mountain plants. This means that the benefit is mutual.

The hypogeal fungus, that is, the truffle, facilitates the plant’s absorption of water, nitrogen, phosphorus and other essential elements, as well as protects it from diseases. In return, the plant provides everything the fungus needs for its development and fruition.

Nutritional value of black truffle

The truffle, apart from being a mystical ingredient, has a nutritional value. According to the analysis of Dr. Pedro Marco Montori, it contains the following nutrients in 100 grams of product:

  • Calories: fifty.
  • Water: 74.7 grams.
  • Carbohydrates: 5.7 grams.
  • Fiber: 10.3 grams.
  • Fats: 0.5 grams.
  • Proteins: 7.4 grams.

  • Magnesium: 28 milligrams.
  • Silicon: 0.37 milligrams.

The black truffle is rich in potassium, magnesium and sodium. Other trace elements present are iron, calcium and silicon. It contains 4 times more nitrogenous matter and minerals than the wild mushroom. It also has vitamin C and B vitamins.

In addition to these nutrients, there are more than 50 different aroma and flavor compounds. Many of them are believed to be produced during the fermentation of sugars, alcohol, and other oxidized compounds.

Most aroma compounds are sulfur. such as dimethyl sulfide; others are aldehydes and ketones, such as methyl 2-butanal and butanone. Phenols are also recorded in truffles.

How to collect the black truffle?

The black truffle is harvested using trained dogs. In France or Spain they can also use domesticated pigs and wild boars, although they are not very frequent due to their gluttony.

Once the dog finds the truffle, the collector (trufero), using a special knife with a triangular blade, he digs to extract it. Then you should cover the hole with the remains of the earth and, if possible, bury some herbs that are nearby.
