shall be marked or labelled with an indication of every such category of additive that is contained in the food.
(2) Any edible ice or flour confectionery which, but for this paragraph, would be required to be marked or labelled in accordance with paragraph (1) need not be so marked or labelled if there is displayed in a prominent position near the edible ice or flour confectionery a notice stating, subject to paragraph (3), that edible ices or flour confectionery, as the case may be, sold at the establishment where the notice is displayed may contain such categories of additives.
(3) Where, in the circumstances described in paragraph (1) or (2), an additive serves more than one of the functions specified in paragraph (1), it shall only be necessary to indicate that category which represents the principal function served by the additive in the food or ingredient to which it was added or in which it was used.
(4) This regulation does not apply to food which is not exposed for sale.
