WHY CHOOSE
BLACK TRUFFLE COLLECTION?

Black Truffle Collection strictly meets all health requirements to guarantee our customers a product that is of the highest quality. We are truffle growers who are concerned with organically producing black truffles and distributors committed to offering our customers the very highest quality. We offer a fresh product with traceability.

Our plantations of holm oaks and oaks lie in an area where truffles grow naturally, within the heart of the region of Sobrarbe in the Huesca Pyrenees. The Black Truffle Collection is the result of perfect harmony in the wonderful Pyrenees ecosystem, whose environment and climate allow us to enjoy the black diamond hidden within its lands.

The morphology of the black truffle that we collect may be rounded or feature a very irregular surface. This is entirely dependent on the texture of the land where it is cultivated.

At Black Truffle Collection, we implement a holistic method to CLEAN, PACKAGE and PRESERVE our truffles, which more than doubles their shelf life, thus guaranteeing greater freshness and enabling the consumption of the product up to 28 days after its collection.

We believe in innovation and, so, we apply a treatment based on a scientific study published by the ‘Instituto Nacional de Investigación Agraria y Alimentaria’ (National Agrarian and Food Research Institute) entitled: ‘Incremento de la vida comercial de la trufa negra: Utilización de métodos combinados. Aplicación de nuevas tecnologías para su conservación’ (Increasing the commercial life of the black truffle: Using new combined technologies. Application of new technologies in truffle conservation). This project, undertaken by a research team from the University of Zaragoza led by Doctor Domingo Blanco Parmo, concluded that by correctly applying the proposed processes, it is possible to ensure a greatly extended shelf life for the truffle as a fresh, quality product.

WE EXTEND THE SHELF LIFE OF THE TRUFFLES TO UP TO 28 DAYS AFTER COLLECTION.
7 ACTIONS THAT MAKE A DIFFERENCE:

At Black Truffle Collection, we combine scientific research with traditional methods in order to preserve the quality and organoleptic properties of the black truffle. Conserving this precious, delicate fungus is a complicated challenge which we have tackled with technical advice from renowned experts in Chemical Sciences and Food Science and Technology. Among this specialised group lies the aforementioned Doctor Domingo Blanco Parmo, coordinator of the innovative study on the application of new technologies to maximise the shelf life of the fresh black truffle in perfect conditions. His indications and techniques have provided us with the scientific base to establish our own cleaning, disinfecting and packaging protocols.

BASIC CLEANING

Our truffles are cleaned with chlorine-free water that has been decalcified. The surface is carefully brushed, with special focus on the more irregular areas, to completely remove any remaining soil left on the rough surface of the fungus.

 

CLEANING AND DISINFECTION

This is vital to have a product which complies with the highest health standards. The truffles are cleaned and disinfected by immersion in an ultrasonic bath, at 35 KHz. This part of the process removes virtually all the microbial load from the  truffle.

DRYING

The truffles are dried by applying a continuous stream of cold air.

QUALITY CONTROL

Using precision optics, we assess the texture and roughness of the truffles, we confirm the variety and check for possible accidental damage. Sometimes it is necessary to take a small sample from the product.

CLASSIFICATION

The truffles are classified according to various pre-established quality control criteria, in particular regarding weight, shape and degree of ripeness.

PACKAGING

Finally, in order to retain the initial qualities of the truffle for longer, it is necessary to control its breathing activity, maintaining a suitable CO2 / O2 ratio. Thus the product is placed in micro-perforated and/or micro-perforated lidded containers.

PRESERVATION

The truffle is preserved at a temperature of between 1º and 4ºC.

 

The result is that you receive a fully guaranteed product, in excellent conditions and with all its original organoleptic qualities intact for up to 30 days after collection.

Our packaging is isothermal and made of extruded polyethylene. It is plasticized with oriented aluminium film and designed to keep the truffles at a controlled temperature of between 4º and 6ºC during shipping (up to 48 hours). Furthermore, all the packaging has passed the controls required under EU Regulation 10/2011 on materials intended to come into contact with food.
