Ultrasonic Truffle Cleaning

Truffles are one of the most prized products in haute cuisine. Their intense aroma, unique flavor, and rarity make them a luxury ingredient. However, their delicacy lies not only in their flavor but also in their handling. Truffle cleaning is a critical step for their commercialization, as impurities, soil, and organic debris must be removed without damaging their skin or altering their culinary value. This is where ultrasonic cleaning technology comes into play, an increasingly popular solution in the gourmet sector.

Discover with DCM Ultrasonic how ultrasonic truffle cleaning works, what advantages it offers compared to traditional methods, and why it represents a qualitative leap for producers, distributors, and companies in the agri-food sector.
 

Why is truffle cleaning so delicate?

Truffles, especially the black (Tuber melanosporum) and white (Tuber magnatum) varieties, grow underground in symbiosis with the roots of trees such as holm oaks. When harvested, they are covered in soil, roots, small stones, and even insects. All of this must be removed without eroding their surface or compromising their texture or aroma.

Manual methods (brushing, pressure washing) are labor-intensive, inconsistent, and can sometimes damage the most fragile truffles. Furthermore, excessive use of water or pressure can accelerate deterioration or increase the risk of rot.

Since truffles are fungi that grow underground, cleaning them is a fundamental step in the marketing process, as are packaging and preservation. These steps ensure maximum freshness.

The usual process includes an initial cleaning phase, followed by cleaning and disinfection, ensuring that the product meets hygiene and sanitation standards. This is followed by cold air drying. Once cleaned, the truffles undergo quality controls, assessing aspects such as their shape, weight, and degree of ripeness before proceeding with their classification. Finally, packaging is carried out with careful control of the oxygen and carbon dioxide ratio, with the aim of preserving their organoleptic properties for as long as possible.














 

Ultrasonic Truffle Cleaning

Discover the benefits of ultrasonic cleaning in the truffle farming industry!

Ultrasonic cleaning is a technology that uses high-frequency waves (generally between 20 and 40 kHz) to generate microbubbles in a liquid, typically water or a harmless solution. This phenomenon is called cavitation, and produces a mechanical action that removes adhered dirt without the need for rubbing or applying pressure.

The principle is simple:

1. An ultrasonic generator transmits energy to a liquid through a transducer.
2. Millions of microbubbles are created, which collapse with controlled force
3. This energy effectively cleans complex, porous, or irregular surfaces.

This treatment significantly contributes to reducing the microbial load present on the mushroom (with an effectiveness rate close to 90%), eliminating any insects or larvae that may inhabit its surface, and significantly extends its shelf life while preserving its organoleptic properties.

DISCOVER OUR IDEAL MACHINES FOR CLEANING TRUFFLES 

The truffles are placed in a tank, where an ultrasonic system generates cavitation. In just a few minutes, the dirt is released naturally:

• Without the need for physical contact.
• Without damaging the rind or peridium.
• Without risk of cutting, eroding, or contaminating the truffle.

The process can be adjusted according to the type of truffle, its degree of soiling, or its ripeness. The equipment allows you to adjust the exposure time and bath temperature for customized cleaning.

Benefits of Ultrasonic Truffle Cleaning

1. Total Product Preservation
Ultrasonic vibration does not damage the texture or structure of the truffle. Unlike mechanical brushing, there is no abrasion or loss of material.

2. Efficiency and Speed
In just 2 to 5 minutes, a truffle can be perfectly clean. This speeds up processes and reduces operating costs.

3. Hygiene and Food Safety
The use of clean water or controlled solutions eliminates not only soil, but also any spores, bacteria, or insects that may remain in the cavities.

4. Uniform Results
Each truffle, no matter how irregular, is cleaned uniformly. It does not depend on the skill of an operator, which improves the quality of the final product.

5. Reduction in water usage
Modern ultrasonic systems are designed to optimize water consumption, working with closed tanks or in a closed circuit, which is much more sustainable than pressure washing.

6. Improved commercial value
A clean, intact, and undamaged truffle has a higher market value. It also facilitates grading and packaging.

Real Cases: Technology at the Service of Luxury
Some truffle cooperatives in Spain, France, and Italy have already incorporated ultrasonic baths into their washing centers. In addition to improving product quality, they have been able to:

• Reduce preparation times by up to 70%.
• Avoid losses due to damaged truffles.
• Extend the product's shelf life thanks to a more thorough and controlled cleaning.
