Using EAN barcode to database and the results sent to the end user would need a two-way communication link and that could possibly mean queueing problems as the database facility would possibly be answering requests from many people.

Somehow this device-relying information system wouldnʼt make me really happy. IMHO the most straightforward communication relies on the packaging, and for this a standardized set of emojis would have been useful.
For more clarity, a textual list may complete the labelling, probably using the Latin scientific names. Every allergic person must then be given by his practician or other health care provider a personal list of allergens, a kind of allergen profile, both in local language and in Latin, plus the pictograph.
We should perhaps take into consideration that allergen lists may be very long, and translating them to emojis will make them somewhat bulky, particularly on small packages. So the emojis will be used only if desired or required.
