Rhodoxanthin (E161f)

Purpose and Function

Rhodoxanthin (E161f) is a naturally occurring red carotenoid from the xanthophyll group. It is found in certain plants, algae, and some birds’ feathers, giving them a reddish hue. In the food industry, rhodoxanthin is used as a natural red to pinkish-orange colorant in various food products. Common applications include:

• Beverages: Used in fruit juices, smoothies, and flavored drinks for a natural reddish tint.
• Confectionery: Added to candies, jellies, and gummies for color enhancement.
• Dairy products: Applied in products like flavored yogurts and ice creams to provide a pink or reddish hue.
• Processed foods: Used in sauces, soups, and savory snacks for color.

Rhodoxanthin (E161f) is valued for its ability to impart natural red tones to foods, making it a natural alternative to synthetic red dyes.

Potential Risks and Side Effects

E161f is considered safe for consumption when used within regulatory limits. It is naturally present in various fruits and vegetables. However, some considerations include:

• Excessive intake: As with other carotenoids, excessive consumption of rhodoxanthin could lead to carotenodermia, a harmless condition where the skin takes on a yellow-orange tint. This effect is temporary and resolves when intake is reduced.
• No known allergies: Rhodoxanthin is naturally found in certain plants and foods and is generally well tolerated by most individuals, with no significant reports of allergic reactions.
• Health benefits: Like other carotenoids, rhodoxanthin may have antioxidant properties, contributing to overall health by helping protect cells from oxidative damage.

Overall, Rhodoxanthin (E161f) is considered a safe, natural additive with potential health benefits, particularly as an antioxidant.
