The mass spec does not know that the presence of citral could indicate the presence of lemon oil. It doesn’t know the difference between folds of essential oils, essences, extracts, or varieties of essential oils. This is where the years of experience in the aromatic industry come into play. By knowing “marker compounds” (compounds that indicate the presence of a specific essential oil or botanical extract), The Flavor and Fragrance Outsource can tell you whether it is lemon or orange or cinnamon patchouli, etc.
