The International Numbering System for Food Additives (INS) is a European-based naming system for food additives, aimed at providing a short designation of what may be a lengthy actual name.[1] It is defined by Codex Alimentarius, the international food standards organisation of the World Health Organization (WHO) and Food and Agriculture Organization (FAO) of the United Nations (UN). The information is published in the document Class Names and the International Numbering System for Food Additives, first published in 1989, with revisions in 2008 and 2011. The INS is an open list, "subject to the inclusion of additional additives or removal of existing ones on an ongoing basis".[1]
INS numbers consist of three or four digits, optionally followed by an alphabetical suffix to further characterize individual additives. On packaging in the European Union (EU), approved food additives are written with a prefix of E. An additive that appears in the INS does not automatically have a corresponding E number.
INS numbers are assigned by the committee to identify each food additive. INS numbers generally correspond to E numbers for the same compound, e.g. INS 102, Tartrazine, is also E102. INS numbers are not unique and, in fact, one number may be assigned to a group of similar compounds.
List of INS numbers
This section is missing information about many/most US approvals; animal feed-only approval (very common on E numbers); approvals that have been retracted + retraction years. Please expand the section to include this information. Further details may exist on the talk page.(May 2019)
Except where stated, the list of INS numbers and associated food additives is based on the most recent publication of the Codex Alimentarius,[2]Class Names and the International Numbering System for Food Additives, first published in 1989, with revisions in 2008 and 2011.
E number and American approval flags are derived from other sources.
In the table below, food additives approved for the EU are listed with an 'E',[3] and those approved for Australia and New Zealand with an 'A'.[4][5] and for the US with a U, even though the US does not use the INS numbering system.
Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities. Some additives have been used for centuries as part of an effort to preserve food, for example vinegar (pickling), salt (salting), smoke (smoking), sugar (crystallization), etc. This allows for longer-lasting foods such as bacon, sweets or wines. With the advent of ultra-processed foods in the second half of the twentieth century, many additives have been introduced, of both natural and artificial origin. Food additives also include substances that may be introduced to food indirectly in the manufacturing process, through packaging, or during storage or transport.
E numbers, short for Europe numbers, are codes for substances used as food additives, including those found naturally in many foods such as vitamin C, for use within the European Union (EU) and European Free Trade Association (EFTA). Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority (EFSA). The fact that an additive has an E number implies that its use was at one time permitted in products for sale in the European Single Market; some of these additives are no longer allowed today.
Food coloring, or color additive, is any dye, pigment, or substance that imparts color when it is added to food or drink. They can be supplied as liquids, powders, gels, or pastes. Food coloring is used in both commercial food production and domestic cooking. Food colorants are also used in a variety of non-food applications, including cosmetics, pharmaceuticals, home craft projects, and medical devices. Colorings may be natural or artificial/synthetic.
Disodium inosinate (E631) is the disodium salt of inosinic acid with the chemical formula C10H11N4Na2O8P. It is used as a food additive and often found in instant noodles, potato chips, and a variety of other snacks.
Quinoline Yellow WS is a mixture of organic compounds derived from the dye Quinoline Yellow SS. Owing to the presence of sulfonate groups, the WS dyes are water-soluble (WS). It is a mixture of disulfonates (principally), monosulfonates and trisulfonates of 2-(2-quinolyl)indan-1,3-dione with a maximum absorption wavelength of 416 nm.p. 119
Sunset yellow FCF is a petroleum-derived orange azo dye with a pH dependent maximum absorption at about 480 nm at pH 1 and 443 nm at pH 13 with a shoulder at 500 nm. When added to foods sold in the United States it is known as FD&C Yellow 6; when sold in Europe, it is denoted by E Number E110.
The Codex Alimentarius is a collection of internationally recognized standards, codes of practice, guidelines, and other recommendations published by the Food and Agriculture Organization of the United Nations relating to food, food production, food labeling, and food safety.
Canthaxanthin is a keto-carotenoid pigment widely distributed in nature. Carotenoids belong to a larger class of phytochemicals known as terpenoids. The chemical formula of canthaxanthin is C40H52O2. It was first isolated in edible mushrooms. It has also been found in green algae, bacteria, crustaceans, and bioaccumulates in fish such as carp, golden grey mullet, seabream and trush wrasse.
Sodium propanoate or sodium propionate is the sodium salt of propionic acid which has the chemical formula Na(C2H5COO). This white crystalline solid is deliquescent in moist air.
Green S is a green synthetic coal tar triarylmethane dye with the molecular formula C27H25N2O7S2Na.
Dimethyl dicarbonate (DMDC) is a colorless liquid and a pungent odor at high concentration at room temperature. It is primarily used as a beverage preservative, processing aid, or sterilant being highly active against typical beverage spoiling microorganisms like yeast, bacteria, or mould.
Caramel color or caramel coloring is a water-soluble food coloring. It is made by heat treatment of carbohydrates (sugars), in general in the presence of acids, alkalis, or salts, in a process called caramelization. It is more fully oxidized than caramel candy, and has an odor of burnt sugar and a somewhat bitter taste. Its color ranges from pale yellow to amber to dark brown.
ISO 22000 is a food safety management system by the International Organization for Standardization (ISO) which is outcome focused, providing requirements for any organization in the food industry with objective to help to improve overall performance in food safety. These standards are intended to ensure safety in the global food supply chain. The standards involve the overall guidelines for food safety management and also focuses on traceability in the feed and food chain.
Colour retention agents are food additives that are added to food to prevent the colour from changing. Many of them work by absorbing or binding to oxygen before it can damage food (antioxidants). For example, ascorbic acid is often added to brightly coloured fruits such as peaches during canning.
Violaxanthin is a xanthophyll pigment with an orange color found in a variety of plants. Violaxanthin is the product of the epoxidation of zeaxanthin where the oxygen atoms are from reactive oxygen species (ROS). Such ROS's arise when a plant is subject to solar radiation so intense that the light cannot all be absorbed by the chlorophyll.
Rhodoxanthin is a xanthophyll pigment with a purple color that is found in small quantities in a variety of plants including Taxus baccata and Lonicera morrowii. It is also found in the feathers of some birds. As a food additive it is used under the E number E161f as a food coloring. It is not approved for use in the EU or US; however, it is approved in Australia and New Zealand.
Hydroxypropyl distarch phosphate (HDP) is a modified resistant starch. It is currently used as a food additive. It is approved for use in the European Union, the United States, Australia, Taiwan, and New Zealand.
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) is an international scientific expert committee that is administered jointly by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO). It has been meeting since 1956 to provide independent scientific advice pertaining to the safety evaluation of food additives. Its current scope of work now also includes the evaluation of contaminants, naturally occurring toxicants and residues of veterinary drugs in food.
The Food Chemicals Codex (FCC) is a collection of internationally recognized standards for the purity and identity of food ingredients.
