The term 'Natural... flavouring' means that it is a synthetic product but at least it contains a natural extract of the ingredient it refers to, in this case the lemon. Manufacturers state that the percentage of the natural ingredient is around 95 per cent, but do not declare the nature of the remaining 5 per cent.

The main raw material for natural lemon flavoring is lemons themselves, most often the peels, which are pressed, dried, or distilled to extract oils and essences.
