What are food additives
In its broadest sense, a food additive is any substance added to food. Legally, the term refers to “any substance the intended use of which results or may reasonably be expected to result — directly or indirectly — in its becoming a component or otherwise affecting the characteristics of any food” 1). This definition includes any substance used in the production, processing, treatment, packaging, transportation or storage of food. The purpose of the legal definition, however, is to impose a premarket approval requirement. Therefore, this definition excludes ingredients whose use is generally recognized as safe (where government approval is not needed), those ingredients approved for use by U.S. Food and Drug Administration (FDA) or the U.S. Department of Agriculture (USDA) prior to the food additives provisions of law, and color additives and pesticides where other legal premarket approval requirements apply.
- Direct food additives are those that are added to a food for a specific purpose in that food. For example, xanthan gum — used in salad dressings, chocolate milk, bakery fillings, puddings and other foods to add texture — is a direct additive. Most direct additives are identified on the ingredient label of foods.
- Indirect food additives are those that become part of the food in trace amounts due to its packaging, storage or other handling. For instance, minute amounts of packaging substances may find their way into foods during storage. Food packaging manufacturers must prove to the U.S. Food and Drug Administration (FDA) that all materials coming in contact with food are safe before they are permitted for use in such a manner.
Food additives can be used to 2):
Improve the taste or appearance of a processed food
- Provide color and enhance flavor: Certain colors improve the appearance of foods. Many spices, as well as natural and man-made flavors, bring out the taste of food. For example, beeswax – glazing agent 3) may be used to coat apples to improve their appearance.
- Give the food a smooth and consistent texture: Emulsifiers prevent liquid products from separating. Stabilizers and thickeners provide an even texture. Anticaking agents allow substances to flow freely.
Improve the keeping quality or stability of a food
- Control the acid-base balance of foods and provide leavening: Certain additives help change the acid-base balance of foods to get a certain flavor or color. Leavening agents that release acids when they are heated react with baking soda to help biscuits, cakes, and other baked goods rise. For example, sorbitol – humectant 4) may be added to mixed dried fruit to maintain the moisture level and softness of the fruit.
Preserve food when this is the most practical way of extending its storage life.
- Improve or preserve the nutrient value: Many foods and drinks are fortified and enriched to provide vitamins, minerals, and other nutrients. Examples of commonly fortified foods are flour, cereal, margarine, and milk. This helps make up for vitamins or minerals that may be low or lacking in a person’s diet. All products that contain added nutrients must be labeled.
- Maintain the wholesomeness of foods: Bacteria and other germs can cause foodborne illnesses. Preservatives reduce the spoilage that these germs can cause. Certain preservatives help preserve the flavor in baked goods by preventing the fats and oils from going bad.
Preservatives also keep fresh fruits from turning brown when they are exposed to the air. For example, sulphur dioxide – preservative 5) is added to some meat products such as sausage meat to limit microbial growth.
Many substances used as additives also occur naturally, such as vitamin C or ascorbic acid 6) in fruit, or lecithin 7), which is present in egg yolks, soya beans, peanuts and maize. The human body cannot distinguish between a chemical naturally present in a food and that same chemical present as an additive.
Side Effects of Food Additives
Most concerns about food additives have to do with man-made ingredients that are added to foods. Some of these are:
- Antibiotics given to food-producing animals, such as chickens and cows
- Antioxidants in oily or fatty foods
- Artificial sweeteners, such as aspartame, saccharin, sodium cyclamate, and sucralose
- Benzoic acid in fruit juices
- Lecithin, gelatins, cornstarch, waxes, gums, and propylene glycol in food stabilizers and emulsifiers
- Many different dyes and coloring substances
- Monosodium glutamate (MSG)
- Nitrates and nitrites in hot dogs and other processed meat products
- Sulfites in beer, wine, and packaged vegetables
The United States Food and Drug Administration (FDA) has a list of food additives that are thought to be safe. Many have not been tested, but most scientists consider them safe. These substances are put on the “generally recognized as safe (GRAS)” list. This list contains about 700 items.
Congress defines safe as “reasonable certainty that no harm will result from use” of an additive. Examples of items on this list are: guar gum, sugar, salt, and vinegar. The list is reviewed regularly.
Some substances that are found to be harmful to people or animals may still be allowed, but only at the level of 1/100th of the amount that is considered harmful. For their own protection, people with any allergies or food intolerances should always check the ingredient list on the label. Reactions to any additive can be mild or severe. For example, some people with asthma have worsening of their asthma after eating foods or drinks that contain sulfites.
It is important to keep gathering information about the safety of food additives. Report any reactions you have to food or food additives to the FDA Center for Food Safety and Applied Nutrition (CFSAN). Information about reporting a reaction is available at: The Center for Food Safety and Applied Nutrition. (https://www.fda.gov/AboutFDA/CentersOffices/OfficeofFoods/CFSAN/ContactCFSAN/default.htm 8)
What Is a Color Additive ?
A color additive is any dye, pigment or substance which when added or applied to a food, drug or cosmetic, or to the human body, is capable (alone or through reactions with other substances) of imparting color. FDA is responsible for regulating all color additives to ensure that foods containing color additives are safe to eat, contain only approved ingredients and are accurately labeled.
Color additives are used in foods for many reasons:
- To offset color loss due to exposure to light, air, temperature extremes, moisture and storage conditions;
- To correct natural variations in color;
- To enhance colors that occur naturally; and
- To provide color to colorless and “fun” foods.
Without color additives, colas wouldn’t be brown, margarine wouldn’t be yellow and mint ice cream wouldn’t be green. Color additives are now recognized as an important part of practically all processed foods we eat.
FDA’s permitted colors are classified as subject to certification or exempt from certification, both of which are subject to rigorous safety standards prior to their approval and listing for use in foods.
- Certified colors are synthetically produced (or human made) and used widely because they impart an intense, uniform color, are less expensive, and blend more easily to create a variety of hues. There are nine certified color additives approved for use in the United States (e.g., FD&C Yellow No. 6. See chart for complete list.). Certified food colors generally do not add undesirable flavors to foods.
- Colors that are exempt from certification include pigments derived from natural sources such as vegetables, minerals or animals. Nature derived color additives are typically more expensive than certified colors and may add unintended flavors to foods. Examples of exempt colors include annatto extract (yellow), dehydrated beets (bluish-red to brown), caramel (yellow to tan), beta-carotene (yellow to orange) and grape skin extract (red, green).
How Are Additives Approved for Use in Foods ?
Today, food and color additives are more strictly studied, regulated and monitored than at any other time in history. FDA has the primary legal responsibility for determining their safe use. To market a new food or color additive (or before using an additive already approved for one use in another manner not yet approved), a manufacturer or other sponsor must first petition FDA for its approval. These petitions must provide evidence that the substance is safe for the ways in which it will be used. As a result of recent legislation, since 1999, indirect additives have been approved via a premarket notification process requiring the same data as was previously required by petition.
When evaluating the safety of a substance and whether it should be approved, FDA considers:
- The composition and properties of the substance,
- The amount that would typically be consumed,
- Immediate and long-term health effects, and
- Various safety factors.
The evaluation determines an appropriate level of use that includes a built-in safety margin – a factor that allows for uncertainty about the levels of consumption that are expected to be harmless. In other words, the levels of use that gain approval are much lower than what would be expected to have any adverse effect.
Because of inherent limitations of science, FDA can never be absolutely certain of the absence of any risk from the use of any substance. Therefore, FDA must determine – based on the best science available – if there is a reasonable certainty of no harm to consumers when an additive is used as proposed.
If an additive is approved, FDA issues regulations that may include the types of foods in which it can be used, the maximum amounts to be used, and how it should be identified on food labels. In 1999, procedures changed so that FDA now consults with USDA during the review process for ingredients that are proposed for use in meat and poultry products. Federal officials then monitor the extent of Americans’ consumption of the new additive and results of any new research on its safety to ensure its use continues to be within safe limits.
If new evidence suggests that a product already in use may be unsafe, or if consumption levels have changed enough to require another look, federal authorities may prohibit its use or conduct further studies to determine if the use can still be considered safe.
Regulations known as Good Manufacturing Practices (GMP) limit the amount of food ingredients used in foods to the amount necessary to achieve the desired effect.
Why Are Food and Color Ingredients Added to Food ?
Food additives perform a variety of useful functions in foods that consumers often take for granted. Some food additives could be eliminated if we were willing to grow our own food, harvest and grind it, spend many hours cooking and canning, or accept increased risks of food spoilage. But most consumers today rely on the many technological, aesthetic and convenient benefits that additives provide.
Following are some reasons why food additives are added to foods 9):
- To Maintain or Improve Safety and Freshness: Preservatives slow product spoilage caused by mold, air, bacteria, fungi or yeast. In addition to maintaining the quality of the food, they help control contamination that can cause foodborne illness, including life-threatening botulism. One group of preservatives — antioxidants — prevents fats and oils and the foods containing them from becoming rancid or developing an off-flavor. They also prevent cut fresh fruits such as apples from turning brown when exposed to air.
- To Improve or Maintain Nutritional Value: Vitamins and minerals (and fiber) are added to many foods to make up for those lacking in a person’s diet or lost in processing, or to enhance the nutritional quality of a food. Such fortification and enrichment has helped reduce malnutrition in the U.S. and worldwide. All products containing added nutrients must be appropriately labeled.
- Improve Taste, Texture and Appearance: Spices, natural and artificial flavors, and sweeteners are added to enhance the taste of food. Food colors maintain or improve appearance. Emulsifiers, stabilizers and thickeners give foods the texture and consistency consumers expect. Leavening agents allow baked goods to rise during baking. Some additives help control the acidity and alkalinity of foods, while other ingredients help maintain the taste and appeal of foods with reduced fat content.

In a laboratory study involving mice 10) dietary emulsifiers promoted colon cancer in a mouse model by altering gut microbes and increasing gut inflammation. Our digestive tract is home to 100 trillion bacteria. Collectively known as the gut microbiota, these bacteria help with metabolism and maintaining a healthy immune system. Changes in this microbial community can cause chronic diseases. Dietary emulsifiers are added to many processed foods to improve texture and extend shelf life. Chemically similar to detergents, they have been shown to alter the mucus barrier and the microbes associated with it. To determine whether these might play a role in chronic diseases, the researchers fed mice low levels of 2 commonly used emulsifiers, carboxymethylcellulose or polysorbate-80, in drinking water or in food 11).
Mice fed the emulsifiers for 12 weeks developed low-grade intestinal inflammation and metabolic syndrome — a group of conditions that increase the risk for type 2 diabetes, heart disease, and stroke. Mice that were genetically engineered to be more prone to inflammation and gut microbe changes developed colitis when fed the emulsifiers.
Mice that consumed the emulsifiers had an altered bacterial composition and thinner intestinal mucus, so that bacteria were closer to the cells lining the colon. The mice also had weight gain, increased food consumption, increased fat mass, and impaired glucose handling, a sign of metabolic syndrome.
When the researchers fed emulsifiers to germ-free mice, which don’t have gut microbiota, the mice showed no signs of gut inflammation, mucus thinning, or metabolic syndrome. This suggests that the effects of the emulsifiers were most likely caused by altering gut bacteria.
When gut microbes from normal, emulsifier-fed mice were transplanted into germ-free mice that hadn’t been fed emulsifiers, the mice developed low grade inflammation, increased fat mass, and glucose intolerance. These results showed that changes in the gut microbiota caused by dietary emulsifiers can drive inflammation and metabolic changes.
Here, the researchers demonstrate in a preclinical model of colitis-induced colorectal cancer that regular consumption of dietary emulsifiers, carboxymethylcellulose or polysorbate-80, exacerbated tumor development. Enhanced tumor development was associated with an altered microbiota metagenome characterized by elevated levels of lipopolysaccharide and flagellin. We found that emulsifier-induced alterations in the microbiome were necessary and sufficient to drive alterations in major proliferation and apoptosis signaling pathways thought to govern tumor development. Overall, our findings support the concept that perturbations in host–microbiota interactions that cause low-grade gut inflammation can promote colon carcinogenesis.
The researchers are now testing additional emulsifiers. They are also designing experiments to examine the effects of food additives in humans.
