Unfortunately with truffle oil this is a problem everywhere. The aromatic compound referred to as “truffle flavour” or “truffle aroma” is so cheap and so ubiquitous it is hard to find a truffle oil without it, and the industry hides it behind these ambiguous descriptions. Perhaps this is not a problem in France, but in Australia it is the same. And AFAICT any truffle oil that lists any ingredient other than ‘oil, truffles’ has had this additive inserted in lieu of using enough truffles to flavour the oil. Many brands even try to disguise this by adding some small pieces of truffle.
