Parma: The rules that decide which food additives reach European shelves are getting stricter, and the change takes effect within weeks. From the twentieth of July, every new application to authorise an additive, or to alter how an approved one is used, must meet updated scientific guidance drawn up by the European Food Safety Authority.

Food additives are the preservatives, colours, sweeteners and stabilisers that industry mixes into processed products. Before any of them reaches a shelf, the authority’s scientists assess whether they are safe at the levels people are likely to consume. The refreshed guidance raises the bar on the evidence companies must supply, reflecting how much toxicology and exposure science have advanced since the previous playbook.

The new requirements reach across the whole dossier. Applicants must characterise their substance more precisely, document manufacturing processes in greater detail, and model dietary exposure with sharper methods. The guidance also asks for fuller toxicological data and, in places for the first time, more explicit attention to environmental safety.

For manufacturers the shift carries real cost. A more demanding evidence standard means longer studies, bigger data packages and, in some cases, a rethink of products that might have sailed through under the old rules. Lawyers advising the sector have told clients to revisit applications already in the pipeline, because anything submitted after the cut-off date will meet the tougher yardstick.

Consumer groups welcome the direction. Public unease about additives has grown, fuelled by debate over ultra-processed food and its links to diet-related disease. A stricter authorisation regime gives regulators a firmer basis to reject substances whose safety case falls short, and gives shoppers more reason to trust what the label does not spell out. Regulators say the tighter regime should also deter weak applications before they ever reach a scientist’s desk.

The authority frames the update as evolution rather than upheaval. Additives already on the market keep their approvals, and the agency continues its separate programme of re-evaluating older permissions in light of new evidence. What changes is the gate through which future additives must pass, and that gate now sits higher.

Parma, home to the authority’s headquarters, has spent years turning food safety into a technical science rather than a matter of national instinct. The updated additive guidance extends that project. It will not change what sits in the supermarket trolley overnight, but over the coming years it will quietly shape which new ingredients ever make it there.
