Sensory Analysis

The quality of Tuber magnatum is evaluated through sight, touch, and smell. Visual inspection involves three key steps: first, confirming that the fruiting body is intact (as damaged truffles spoil more quickly); second, assessing cleanliness (soil residues can hide imperfections); and third, subjectively evaluating the truffle’s aesthetic appeal and overall appearance.

This is followed by a texture assessment: a high-quality truffle should feel elastic, firm, and compact—neither too hard nor overly soft or rubbery.

The final stage is aroma evaluation. The scent of the truffle is composed of a broad spectrum of aromas with varying intensity, which is what makes it so prized in the culinary world. Common descriptors for the aroma of Tuber magnatum include: fermented or mushroom-like, honey, hay, garlic, spice, damp earth, and ammonia.
