I'm trying to find out if you have to put an E number on your label for ALL ingredients that may have an e number? Specifically Sulphur Dioxide, Potassium sorbate & Tartaric acid? Maybe you know of a document setting this legislation out? I can’t find anything definitive on the net. There are plenty of lists setting out all of the numbers but they don’t say what one has to declare on the label! I’m specifically interested in the EU legislation.
Thanks in advance!
