The Rulebook Behind the List: Understanding Annex II Part A of the EU Food Additives Law
How the Union list of authorised additives is built and governed – the general provisions of Annex II Part A, explained by InfoCons
The instructions that make the Union list work – InfoCons Consumer Protection
Annex II of Regulation (EC) No 1333/2008 contains the Union list of food additives authorised for use in foods and their conditions of use. It is the single most consulted part of the whole regulation, because it is where the practical answers live: which additive may go into which food, and in what amount. But a list of that size needs instructions on how to read it, and those instructions are set out in Part A. This InfoCons – Consumer Protection article explains what Annex II Part A says and why it matters to consumers.
Part A is the introduction and the general provisions of the Union list. It defines what information each entry contains, sets out the rules that apply across the whole list, and connects Annex II to its other parts. Understanding Part A is like understanding the key to a map: without it, the detailed entries can be misread; with it, they make sense. For InfoCons – Consumer Protection, Part A is proof that transparency depends not only on publishing information but on making it usable.
What each entry in the Union list contains – InfoCons Consumer Protection
According to Part A, the Union list includes, for each additive, the name of the food additive and its E number. It also specifies the foods to which the additive may be added, the conditions under which it may be used, and any restrictions on selling the additive directly to the final consumer. Part A also notes that more specific E numbers and names, as laid down in the Commission regulation on specifications, may be used as an alternative in certain cases.
This structure means that an entry is never just a name. It always ties the additive to particular foods and particular conditions. The permission to use an additive is therefore inseparable from the context: an additive allowed in one food at one level is not automatically allowed in another. Part A makes this conditional logic explicit, and it is the reason the same E number can appear with different limits in different products.
The general provisions: how the whole list is governed – InfoCons Consumer Protection
Part A lays down general provisions that apply across the list. First, only the substances listed in Part B, as specified in the regulation on specifications, may be used as additives in foods, except where specifically provided in Part E. Second, additives may be used only in the foods and under the conditions set out in Part E of the annex. Third, the foods in Part E are listed on the basis of the food categories defined in Part D, and the additives are grouped on the basis of the definitions in Part C.
This cross-referencing is the backbone of the system. Part B is the roster of substances; Part C defines groups of additives; Part D defines the food categories; and Part E brings them together, stating which additives are allowed in which categories and at what levels. Part A is the guide that tells you how these parts interlock, so that the list can be applied consistently and unambiguously across the whole Union.
Special rules that protect the consumer – InfoCons Consumer Protection
Part A also contains specific rules that carry real consumer significance. It provides rules on aluminium lakes prepared from colours, tightening over time which lakes are permitted and in which categories, reflecting attention to aluminium intake. It states that certain colours – namely E 123, E 127, E 160b, E 161g, E 173 and E 180 – and their mixtures may not be sold directly to consumers. It allows certain substances (E 407, E 407a and E 440) to be standardised with sugars provided this is indicated, so the consumer is not misled. And it requires that nitrite, when labelled for food use, may be sold only in a mixture with salt or a salt substitute.
Each of these rules addresses a concrete risk of consumer harm or confusion, from limiting aluminium exposure to preventing the direct retail sale of colours that warrant professional handling, to ensuring that a preservative as potent as nitrite cannot be sold in a concentrated, easily misused form. They show that Part A is not merely procedural but actively protective.
The carry-over rule and the foods it protects – InfoCons Consumer Protection
One of the most consumer-relevant elements of Part A is its treatment of the carry-over principle. Article 18 generally allows an additive to be present in a compound food if it was permitted in one of the ingredients. Part A, however, sets out tables of foods in which this carry-over is not permitted. Table 1 lists foods in which the presence of an additive may not be authorised through carry-over for additives in general, and Table 2 lists foods in which carry-over may not bring in colours.
Table 1 covers, among others, unprocessed foods, honey, non-emulsified oils and fats, butter, unflavoured pasteurised and sterilised milk and cream, unflavoured fermented milk products, natural mineral water and spring water, coffee and coffee extracts, unflavoured tea leaves, sugars, dried pasta, and foods for infants and young children. Table 2 shields foods such as unprocessed foods, all bottled or packaged waters, and unflavoured milk from colours introduced by carry-over.
For the consumer, these tables are a powerful guarantee. They mean that certain staple foods – fresh produce, plain milk, honey, water, sugar, coffee, tea – are protected from acquiring additives indirectly through their ingredients. The law does not merely control what is added directly; it also controls what may enter through the back door of carry-over, keeping our most basic foods as clean as consumers expect them to be.
How much may be used: conditions, limits and quantum satis – InfoCons Consumer Protection
Being authorised is only the beginning. Under Regulation (EC) No 1333/2008, every additive may be used only in the specific food categories set out in the Union list and only under the conditions attached to each entry. For many substances the list sets a numerical maximum level, expressed in milligrams per kilogram of food; for others it applies the quantum satis principle, meaning no fixed numerical limit is set and the substance must be used in accordance with good manufacturing practice, at no more than the level needed to achieve the intended effect, and without misleading the consumer.
The regulation also requires that the amount used be limited to the lowest level necessary to obtain the desired technological effect. Where maximum levels apply, they take into account the acceptable daily intake established for the substance and the likely intake from all dietary sources, including for special groups such as children. As a rule, maximum levels apply to the food as marketed, with a specific adjustment for dehydrated or concentrated foods that must be reconstituted before consumption.
For the consumer, this means that the presence of a additive on a label does not imply it can be used without limit. On the contrary, its use is bounded by category, by purpose and, in many cases, by a precise maximum. InfoCons – Consumer Protection considers these conditions of use one of the most important, and least understood, protections in the whole system.
Safety first: assessment, ADI and re-evaluation – InfoCons Consumer Protection
No additive reaches the Union list without first being assessed as safe at its proposed levels of use, on the basis of the available scientific evidence. For many additives, scientific bodies establish an acceptable daily intake, or ADI – an estimate of the amount that can be consumed every day over a lifetime without appreciable risk. The conditions of use are then set so that realistic consumption across the whole diet is expected to remain within this safe boundary.
Crucially, authorisation is not permanent and untouchable. The European Union has committed to a systematic re-evaluation of previously approved additives by the European Food Safety Authority in the light of current scientific knowledge. Producers and users are also legally obliged to report immediately any new scientific or technical information that might affect an additive safety assessment. Together, these mechanisms mean that each additive remains under review and its authorisation can be maintained, tightened or withdrawn as the evidence evolves.
InfoCons – Consumer Protection views this combination of prior assessment and continuous re-evaluation as the backbone of consumer confidence. It allows consumers to treat an authorised additive as one that has been vetted, while understanding that the system remains vigilant rather than complacent.
How this class is shown on the label – InfoCons Consumer Protection
On an ordinary retail food, a additive is declared in the ingredient list using the name of its functional class followed by either the specific name of the substance or its E number. So you might see the functional class named, and then a substance name or an E code such as a number in the relevant series. This dual system means that even if you do not recognise a chemical name, the functional word already tells you the job the substance performs, while the E number lets you identify it precisely and consistently across languages and countries.
This labelling rule is what makes a additive visible to you in the first place. European law does not permit such substances to be used silently; when present and performing a technological function, they must be declared. The transparency is built in, and it applies equally to well-known and to obscure substances. The practical challenge for the consumer is simply to read and interpret the declaration quickly, which is exactly where clear knowledge of the functional classes, and simple digital tools, make all the difference.
It is also worth knowing that the same substance can appear under different functional descriptions on different products, because many additives are multifunctional. The functional word on a specific label always tells you the role the substance is playing in that particular food, even if the same E number does a different job elsewhere.
Natural, nature-identical or synthetic? – InfoCons Consumer Protection
A common misunderstanding is that every E number denotes an artificial chemical. In reality, additives within a single functional class can come from very different origins: some are extracted from natural sources, some are nature-identical versions of substances found in nature, and some are produced synthetically. The E number identifies the substance and confirms it is authorised; it does not, on its own, tell you whether the source is natural or synthetic.
This matters because consumers often have legitimate preferences about origin, whether for dietary, ethical or personal reasons. Reading the specific name behind the functional class – not just the fact that a additive is present – is what allows an informed choice. InfoCons – Consumer Protection encourages consumers to look past the general fear of E numbers and to focus instead on the specific substances and their documented roles.
Smart shopping: putting this category in perspective – InfoCons Consumer Protection
The practical takeaway for shoppers is neither alarm nor indifference, but attention. Knowing what a additive does, recognising it on a label, and understanding that its use is limited by law allows you to judge products calmly and compare them meaningfully. Two similar products can differ substantially in how many additives they contain, and the more informed you are, the easier it is to choose according to your own priorities.
It is also worth remembering that a additive never acts in isolation on the shelf. Products are formulated as whole recipes, and the same food may combine this class with colours, preservatives, emulsifiers, stabilisers and others, each performing its own job. Comparing similar products side by side often reveals striking differences: one may rely on a long list of additives while another achieves a similar result with only a few. This variety is precisely what gives the informed consumer room to choose.
Above all, InfoCons – Consumer Protection emphasises the cumulative picture. A single product may contain several additives, the same additive may recur across many products in your basket, and a single meal can bring together additives from several sources at once. The real question is therefore not only what each label says, but how many additives you accumulate across your whole shopping and across your day. That is the perspective that turns label-reading into genuine control over your diet, and it is the personal layer of protection that the law itself cannot provide for you.
The InfoCons Additives Calculator: how many additives are really in your basket? – InfoCons Consumer Protection
Understanding the law is one thing; seeing what it means for your own shopping basket is another. A single processed product can contain several additives at once, and an ordinary weekly shop can add up to dozens or even hundreds of additive occurrences once you sum every product together. What is more, the same additive can appear in many different products in the same basket, which means it enters the consumer’s diet repeatedly.
To answer this, InfoCons – Consumer Protection offers consumers the Only Additives Calculator for the food products bought or consumed. It is the only calculator for food shopping that shows the number of additives present and how many times a given additive is found in the shopping basket. Instead of looking at each product in isolation, the consumer gets a complete picture of the whole basket, seeing the real, cumulative number of additives being purchased.
The same logic applies to a single meal. A breakfast, a lunch or a dinner can bring together several processed products, each with its own set of additives. When these products are eaten together, the additives add up. A seemingly simple meal can, in reality, mean the simultaneous consumption of a surprisingly large number of food additives – colours, preservatives, emulsifiers, flavour enhancers, stabilizers and more. That is why the question “how many additives do I consume at one meal?” is just as important as “how many additives am I buying?”
As a practical solution, the InfoCons application helps consumers identify additives quickly. By scanning the barcode of an agri-food product, the app identifies the product and shows the food additives it contains, turning the “E” codes on the label into clear, easy-to-understand information. In this way, consumers can see how many additives are cumulated in their shopping basket or even in a single meal, and can make informed choices for themselves and their families – right there, in front of the shelf.
