On February 1, 2026, Report (Rai3) devoted its investigation Truffle Land to the lesser-known side of the truffle market. For many, it was an eye-opener; for us at Casole Truffle, it’s a battle we’ve been fighting for years, and one we share with everyone who comes hunting truffles with us. The question a lot of people are asking after watching is simple: how do I know if the truffle cream I’m buying actually contains truffle, and not just a scent made in a lab?
A battle we’ve been fighting for years
Long before it made it to television, the problem already had a name for us: synthetic aroma and the standardized production the market demands. It’s something we talk about during our hunts, because knowing the product is the first way to defend it. We have nothing against those who choose to consume an altered, non-natural product: everyone is free to eat what they like, but it’s fair to know what we put on our plate and how we spend our money.
What “truffle aroma” really is
When a label simply says “flavorings,” there’s often a single molecule behind it: bis(methylthio)methane (2,4-dithiapentane). This isn’t a minor detail — this molecule reproduces part of the aromatic bouquet of the white truffle (Tuber magnatum Pico), the rarest and most expensive one, and it often replaces the truffle in the recipe entirely.
Although it was originally isolated from white truffle, today it’s synthesized at very low cost, and just a few drops give an oil, a butter, or a sauce an intense “truffle” smell — even when there’s very little real truffle inside, and when there is some, it’s often not even white truffle.
There’s a side effect rarely talked about: the indiscriminate use of this molecule has ended up warping consumers’ perception altogether. For many people today, the word “truffle” is synonymous with that intense artificial scent — to the point that we no longer know what other truffles actually smell like.
So what am I actually buying at the supermarket?
This aroma is used indiscriminately across all kinds of products: salt, honey, aged cheeses, packaged commercial chips, creams, olive oil. To include a minimal percentage of truffle and be able to write “with truffle” (very different from “truffle-flavored”) on the label, producers use summer truffle (Tuber aestivum Vitt.) for two reasons: it’s widely available and inexpensive, and its dark skin is clearly visible inside the product.
The percentages are often small (5–10%) — present, but barely so. Its authentic profile ends up completely masked by the molecule, with one single result: you’re no longer tasting truffle, you’re tasting the molecule.
How many people truly know the scent of summer truffle? Its mushroomy, woodland notes, delicate and elegant, are only really distinguishable in fresh truffle — which often doesn’t even seem like “real” truffle to us anymore, precisely because we’ve grown used to the synthetic aroma.
But is it bad for your health?
Honesty matters here, because there’s a lot of fear circulating online. We checked: there’s no evidence showing it’s harmful at the levels used in food, and it’s actually an authorized flavoring with published safety assessments. It’s true that it’s synthesized from petroleum derivatives, and that understandably feels uncomfortable — but the final molecule is chemically identical to the natural one. So the problem isn’t poison: it’s deception. You’re paying for the scent of the world’s most prized truffle while believing you’re buying truffle, when often you’re buying an aroma worth a few cents.
What the law says (and why almost no one knows it)
Italian truffle law is more advanced than most people think: it requires that truffle, whether fresh or preserved, be labeled with its Latin name as well as its Italian one — meaning the exact species — and, for fresh truffle, the harvesting area. The regulations behind food preparations prohibit presenting something as “truffle” when its scent actually comes from an added aroma: the aroma must be declared. The weak point isn’t the law itself, it’s enforcement, which remains minimal across the supply chain. That’s why, today, reading the label remains the consumer’s real defense.
How to recognize an authentic truffle cream
Four quick checks before putting a jar in your cart:
- Read the ingredient list. It should be short. If you see “flavorings” (instead of truffle listed with its species), you’re likely paying for lab-made scent.
- Look for the species and the Latin name. A transparent producer states exactly which truffle they use — Tuber aestivumVitt., Tuber magnatum Pico — and in what percentage.
- Be wary of minimal percentages. Many products contain just enough truffle to put it on the label and in the photo. Very often the first ingredients you’ll find are dairy derivatives or button mushrooms with almost no flavor, added simply to bulk out the jar.
- Look at the price. A genuine truffle preparation can’t have a bargain price of a few euros. Our advice? If you want to be sure, eat fresh truffle.
The “problem” with standardized production
There’s one last point close to our hearts. Mass retail wants a product that’s always the same, jar after jar. But a real truffle is never the same — like all natural, non-industrial products — its aroma and texture change with the season, with the balance between heat and humidity, even with the soil.
A product’s variability, then — much like a wine’s vintage — should be seen as a mark of quality, not a commercial shortcoming.
In a cream like ours, for example, it’s impossible for two batches to be identical — and that’s exactly the sign that there’s nature inside, not a formula. Perfect uniformity is almost always the sign of something else.
Casole Truffle creams
Our creams are built on the opposite idea of scent-in-a-jar. We created them, first and foremost, to showcase the quality of our work in the field — more a statement of value than a business. The ingredient list says it better than any slogan:
- Summer truffle (Tuber aestivum Vitt.) 82%
- Extra virgin olive oil
- Salt
- Anchovies (omitted in the vegan version, Susy)
Nothing else. No added aroma, whether natural or synthetic: what you taste is the scent of real truffle, in its true measure.
You’ll find all our creams — Olli (pesto), Zara (cream), and Susy (vegan) — in our shop.
Frequently asked questions
Which truffle does the synthetic aroma imitate?
It reproduces part of the aromatic bouquet of the white truffle (Tuber magnatum Pico), the most prized one. It’s a single molecule, bis(methylthio)methane, now produced cheaply in a lab.
Is truffle aroma bad for you? There’s no evidence it’s harmful at food-use levels, and it’s an authorized flavoring. The issue isn’t health — it’s paying for lab-made scent while believing you’re paying for truffle.
How do I know if a truffle cream is real? Read the ingredients: they should list the truffle with its species (Latin name) and a percentage, not the generic word “flavorings.” Be wary of “truffle-flavored” products.
Where can I buy truffle cream without synthetic aromas? In our online shop: creams with 82% summer truffle that we hunt ourselves, organic extra virgin olive oil, salt, and anchovies (or without, in the vegan version).
To close
“Truffle oil is like tofu ‘meat’ — something got lost in the name.”
It’s a provocation, sure — but with a precise goal: to lift the lid on a real Pandora’s box. We have nothing against tofu, quite the opposite!
The point isn’t the food itself, but the way we use words: we believe a name shouldn’t be a marketing tool designed to exploit the consumer’s imagination, but an honest way of telling people what a product truly is. To us, the customer isn’t a “target to convince,” but a person to respect — and respect also means accurate information, one that lets people choose freely, knowingly, and without being misled.
