Purpose and Function

Alkannin is a natural red pigment extracted from the roots of the Alkanna tinctoria plant, commonly known as the alkanet. It is primarily used as a colorant in food and cosmetics due to its vibrant red hue. The main purposes and functions of alkannin in the food industry are as follows:

  • Colorant: Alkannin is used as a natural food colorant, providing a red to violet hue to products. It is a popular choice in products where natural coloring agents are preferred over synthetic dyes. Alkannin is used in various foods, beverages, and confections to achieve the desired red coloration.
  • Cosmetic Use: Beyond its use in food, it is also employed in the cosmetic industry to color lipsticks, lotions, and other skincare products. It has been valued for its stable color properties in oil-based formulations.
  • Traditional Uses: Historically, alkannin has been used as a dye for textiles and as an ingredient in herbal medicine for its purported anti-inflammatory and wound-healing properties.

Alkannin’s use as a colorant is favored for its natural origin, making it suitable for products marketed as natural or organic.


Potential Risks and Side Effects

E103 is generally regarded as safe when used in food and cosmetics. However, there are some potential concerns and considerations:

  • Allergic Reactions: While rare, some individuals may experience allergic reactions to alkannin, especially when used in topical cosmetic products. Symptoms can include skin irritation, redness, or itching.
  • Toxicity Studies: Animal studies have shown that high doses might have hepatotoxic (liver-damaging) effects. However, these findings are typically associated with doses much higher than those used in food products.
  • Regulatory Status: Alkannin is not approved as a food additive in all regions, which limits its use in certain markets. It is important for manufacturers to comply with local regulations regarding its application in food products.

Overall, E103’s safety profile in food use is considered acceptable, but its application should be in compliance with regulatory standards.
