Exploring the World of Food Colorants

Food colorants, as the name suggests, are substances that impart color to food items or restore their original color. These colorants can be derived from natural food components or other natural sources that are not typically consumed as food or used as a regular food ingredient.

Understanding Food Colorants

Food colorants are substances that come from natural sources like foods and other edible materials. They are made through physical or chemical methods, which focus on pulling out the color pigments without changing the food's nutrition or smell.

There are two key types of food colorants. The first type is called edible colors, which are mixed into foods directly. The second type is used to color the surface of foods, for example, the outer layer of cheeses or the designs on Easter eggs. This group is generally not applied to the parts of the food we eat.

Classification of Food Colorants

Food colorants can be broadly classified into two categories based on their potential side effects:

  1. Dyes without Side Effects: This category mainly includes vitamin groups (such as vitamin B2), provitamins (such as beta-carotene), and natural components such as chlorophyll, carotenoid, and beetroot. These colorants are generally considered safe, and they can be used in foods without specific indications.
  2. Dyes with Side Effects: Certain dyes, especially azo dyes, can pose a potential risk factor for human health. These dyes can sometimes cause allergic reactions, even in very small amounts. These reactions are particularly common in individuals who have allergies to specific substances.

Application of Food Colorants

The use of food colorants is not universal. They are typically used in the following food categories:

  • Confectionery: This includes icings, sugar-based products, cocktail cherries, candied fruit, packaged ice creams, and marzipan.
  • Fish: Fish roe products, jarred shrimp, and canned salmon fillets often contain food colorants.
  • Other products: Low-calorie jams, creams, jellies, puddings, sweet sauces, soups, effervescent drinks, packaged drinks, margarine, cheeses, herbal liqueurs, and certain types of preserves also contain food colorants.

The use of food colorants is subject to regulations and varies by region, and not all products within these categories will necessarily contain colorants. It's always good practice to check product labels for specific information.

Labeling of Food Colorants

Food colorants often have complex chemical compositions, which can make their labeling seem complicated. These are typically listed by their specific chemical names or designated numbers (such as E-numbers in the European Union).

The specifics of labeling regulations can vary by country or region. For instance:

  • In the European Union and many other regions, it is mandatory to clearly indicate the presence of colorants in foods. This is often done by stating "colored with [name of the colorant]" on the label.
  • In the United States, the Food and Drug Administration (FDA) requires that food color additives must be declared in the ingredient statement on the food label. The label should specify each color additive by its common name (e.g., "FD&C Red No. 40" or "Red 40").

The specific names of the colorants used in a food product are typically listed in the ingredients section, along with other additives. This allows consumers to identify specific colorants used, which is particularly important for those with allergies or sensitivities to certain additives.

It's important to note that regulations regarding food labeling, including the indication of colorants, can differ significantly depending on the jurisdiction. For the most accurate information, one should refer to the specific food labeling laws applicable in their region.

Classification of Dyes

Food colorants can be classified based on the color they impart to the foods and their origin. Here is a simple classification based on the color they provide:

  • E100-109: Yellow color
  • E110-119: Orange color
  • E120-129: Red color
  • E130-139: Blue color
  • E140-149: Green color
  • E150-159: Brown-Black color
  • E160-199: Mixed colors


Food colorants play a significant role in making our food appealing. However, it's essential to be aware of the potential side effects of certain dyes and make informed choices when purchasing food products. Always check the labels and understand what each colorant means for your health.
