Yes, they probably lose some, but they don't lose much. For example, I had a boat load of chopped truffle left over from last night, and upon opening the fridge it was like being hit by a truffle in the face this evening. You would think they lose everything quickly, since you really only see them shaved at the table (and that will be a $40 supplement good sir) but that is about theatrics and the supplement more than the truffle. Also, they are not best so thin like they are shaved. Thin, but not too thin. For the tart the truffles are brushed with goose fat before they are stuck together, so they are pretty much hermetically sealed.
