Properties: Colorants
Food colorants are chemical substances used to give food color or enhance its visual appeal. They have specific properties and characteristics:
Coloring: The main function of food colorants is to provide color to foods. They can produce a wide range of colors, from vivid and strong tones to delicate and pastel shades.
Solubility: Food colorants must be able to dissolve or disperse in the liquid or medium in which they are used. This allows for an even distribution of color throughout the food product.
Stability: Food colorants should be stable and retain their color under food processing and storage conditions. They should not degrade due to heat, light, oxygen, or pH changes.
Taste neutrality: Food colorants are typically taste-neutral so as not to affect the flavor of the food in which they are used. They should not add unwanted aromas or odors.
Safety: Food colorants must be safe for consumption. In most countries, there are strict regulations and testing procedures to ensure the safety of food colorants.
Compatibility: Colorants should be well compatible with other ingredients in foods and should not cause undesirable chemical reactions or precipitations.
Reversibility: Some food colorants are reversible, meaning they can change under certain conditions. This can be useful for achieving the desired color in a product and then changing the color over time to monitor product quality.
It is important to note that the use of food colorants is strictly regulated in many countries to ensure their safety and compliance with the above properties. The use of colorants in foods therefore requires careful selection and dosing to achieve desired aesthetic goals without compromising the quality or safety of the food.
Origin: Colorants
The origin of food colorants can be diverse. Food colorants can be synthetically produced or of natural origin. Natural food colorants often come from plants, fruits, vegetables, insects, or minerals. Examples of natural colorants are carmine (from cochineal scale insects), curcumin (from turmeric), chlorophyll (from plants), and anthocyanins (from berries). Synthetic food colorants are produced through chemical processes and can produce a wide range of colors. They are often made from petrochemical raw materials. Examples of synthetic colorants are Tartrazine (Yellow 5), Azorubine (Red 122), and Brilliant Blue FCF (Blue 1). The origin of the colorants should be indicated on food labels to provide transparency for consumers.
Uses: Colorants
The use of colorants in foods is intended to enhance the visual appeal and aesthetic quality of foods without significantly altering their taste or aroma. Colorants are added to foods for various reasons, including:
Coloring: Colorants give foods a wide range of colors to make them more appealing and attractive to consumers.
Brand Identification: Certain colors can be associated with specific brands or products. The use of colorants can contribute to ensuring brand identity and product consistency.
Seasonal or Thematic Adaptation: Food manufacturers can use colorants to adapt products for certain seasons or holidays. For example, red and green colorants could be used around Christmas.
Product Differentiation: Colorants can help visually distinguish similar food products from each other, even if they have similar ingredients.
Kid-friendly Products: In some cases, colorants are used to make foods more attractive for children.
It is important to note that the use of colorants in foods is subject to strict regulations and guidelines in most countries. These regulations set maximum limits for the use of colorants and monitor their safety and quality. Food colorants must typically be listed on food product labels so consumers are informed about their presence.
Storage: Colorants
The storage of colorants in foods requires specific measures to ensure the quality and stability of the colorants. Here are some important points for storing food colorants:
Temperature: Food colorants should be stored in a cool and dry storage area. Storage at room temperature is often sufficient. Extreme temperatures, whether very high heat or cold, should be avoided as they can affect the stability of the colorants.
Light Protection: Colorants can be affected by light sensitivity. Therefore, they should be protected from direct sunlight or intense lighting. This can be achieved through the use of lightproof packaging or storage rooms.
Airtight Sealing: The packaging of colorants should be airtight to keep moisture and oxygen away. Moisture can cause colorants to clump, while oxygen can affect their stability.
Separate Storage: Colorants should be stored separately from strongly scented or aromatic substances as they can easily absorb odors and aromas.
Expiration Date: Most food colorants have a shelf life or expiration date. Make sure to use the colorants before they expire to ensure quality and desired coloring results.
Hygiene: Ensure that the storage environment is clean and hygienic to prevent contamination of the colorants.
The specific requirements for storing colorants can vary depending on the type of colorant and manufacturer instructions. It is advisable to check the packaging or accompanying documents for instructions and follow them carefully to maintain the quality of the colorants.
Health: Colorants
The effect of food colorings on health can vary from person to person. Generally, food colorings are considered safe when used according to legal regulations. However, some people may react allergically to certain colorings or develop intolerances. There have also been concerns regarding the possible effects of synthetic colorings on children with Attention-Deficit/Hyperactivity Disorder (ADHD). Therefore, individuals who react sensitively to colorings should carefully read labels and pay attention to their individual reactions.
Season of Colorants:
The use of food colorants in foods is strictly regulated in many countries to ensure the health and safety of consumers. However, there is no specific "season" for food colorants as they can be used throughout the year in foods according to the requirements of manufacturers and consumer preferences.
Food colorants are often used to give foods color or enhance their visual appeal. They may be present in products such as candies, beverages, baked goods, pastries, snacks, and many other foods. The choice and use of colorants can vary by season, holidays, or special occasions as some food manufacturers release products with seasonal themes.
It is important to note that the use of food colorants is strictly regulated in some countries, and there may be maximum limits set for the amount and type of colorants used. This ensures that consumers are protected from health risks.
If you seek specific information about food colorants or their usage during a particular season or context, you should consider the regulations and practices of your country or region as well as the labels and product information on foods.

Colorants taste: Colorants are generally taste-neutral, which means that they usually do not have a significant taste or aroma and do not affect the flavor of the food in which they are used.
Additives (E numbers) in Foods
The more appealing a product looks, the more likely it is to be purchased. However, many people overlook that, for example, in pineapple yogurt, it's not necessarily the case that particularly good fruit was used and generously added, but rather that it’s merely an illusion created by colorants. Colorants (E numbers) cannot be consumed by everyone because they can cause allergies. Therefore, it is naturally also important to understand the significance of additives and colorants (E numbers).
History of Colorants
The history of colorants is also interesting. Towards the end of the 19th century, synthetic colorants were used in the dyeing industry. They fascinated because they colored more effectively than natural colorants previously used. It's hard to believe, but there were no laws for food coloring as late as 1875. Therefore, it could not be prevented that many foods were treated with toxic colorants, such as mercury sulfide in cheese. This and other colorants could cause significant harm to people. In 1887, a law was finally enacted for foods banning heavy metal additives. Until the year 1970, new laws continued to emerge, reducing synthetic colorants further. It's also alarming that it wasn't until 1993 that food legislation was harmonized across Europe. Even today, not all additives are used in every country. Unfortunately, many additives and their risks for humans have yet to be researched, which should alarm consumers.
Only 40 approved food colorants are allowed in the present day. Among them, there are still some metals. All extracted colorants that are added to foods must be labeled. However, if a colorant is already present in a specific substance and is no longer extracted, the manufacturer does not have to label this substance. Even when a manufacturer chooses Carotin, a natural colorant (E 160a), they must also label it.
Colorants (E numbers) and their Significance
Manufacturers are required to provide information about the contents of foods. E numbers are consistent across all countries, and once you understand their meaning, you can recognize them abroad without needing to speak that language. This is advantageous; unfortunately, one must first know the significance of the E numbers. There are various ways to do this. Firstly, there are many books dedicated solely to additives and colorants (E numbers). A so-called food lexicon translates all E numbers.
Those who don't want to buy an expensive book can also use the internet, where numerous options exist to find out about E numbers and their meanings. This way, one quickly learns that for example, E 100 stands for Curcumin, a colorant obtained from turmeric or synthetically produced. Or that E 102 means Tartrazine, which is even banned in some countries because it can cause allergies and asthma. Staying briefly on this topic, many doctors advise against consuming additives and colorants (E numbers) due to the high allergy risk.
