E161B – Lutein

E161b, commonly known as Lutein, is a natural carotenoid pigment that imparts yellow to orange hues in various food products. It is naturally present in green leafy vegetables, egg yolks, and marigold flowers. Commercially, lutein is often extracted from marigold flowers (Tagetes species) for use as a food additive. 

Purpose in Products

Lutein (E161b) is utilized to provide a yellow to orange color to consumables, enhancing their visual appeal. It is commonly found in products such as:

  • Dairy Products: Flavored yogurts and cheeses.
  • Beverages: Fruit juices and soft drinks.
  • Confectionery: Candies and desserts.
  • Bakery Products: Cakes and pastries.

Its natural origin and vibrant color make it a preferred choice in food processing. 

Health Considerations

Lutein is generally recognized as safe for consumption and is associated with several health benefits:

  • Antioxidant Properties: Lutein exhibits antioxidant activity, which may help in reducing oxidative stress in the body.
  • Eye Health: Lutein is known for its role in maintaining eye health, particularly in protecting the eyes from blue light and reducing the risk of macular degeneration.

The European Food Safety Authority (EFSA) has evaluated lutein and established an Acceptable Daily Intake (ADI) of 0-2 mg/kg body weight. 

Impact on Children

Lutein is considered safe for children when consumed within recommended dietary limits. There is no specific evidence indicating adverse effects on children beyond general dietary considerations.

Impact on Taste

As a colorant, lutein has a neutral flavor profile and does not significantly alter the taste of the products to which it is added.

Compatibility with Other Additives

Lutein is compatible with a wide range of food additives and ingredients, making it versatile for various formulations without causing undesirable interactions.

Natural Occurrence

Lutein occurs naturally in several fruits and vegetables, including:

  • Green Leafy Vegetables: Spinach, kale, and broccoli.
  • Egg Yolks
  • Marigold Flowers

The concentration of lutein varies among these sources, with green leafy vegetables being particularly rich in this pigment. 

Alternatives and Substitutes

Natural alternatives to E161b include other carotenoid-based colorants such as:

  • Beta-Carotene (E160a): Provides yellow to orange hues.
  • Annatto (E160b): Offers an orange-red color.
  • Paprika Extract (E160c): Imparts a red hue.

The choice of alternative depends on the desired shade and compatibility with the food product.

Regulation
