A Smart Shopper's Guide: How to Identify Red Dye in Food?

According to the Environmental Working Group (EWG), artificial food dyes, including red ones, are present in thousands of consumer food products. Knowing how to identify red dye in food is a crucial skill for anyone aiming to reduce their intake of artificial ingredients, empowering you to make healthier, more informed choices for yourself and your family.

Quick Summary

This article reveals how to locate both artificial and natural red dyes in packaged foods by carefully reading ingredient labels. It details the common names and codes for different red colorants, including Red 40, Red 3, and carmine, and provides a comparative look at their sources and stability. The guide also offers practical tips for avoiding these additives in various products.

Key Points

• Check the Label First: The most effective way to identify red dye is by reading the ingredients list on a product's packaging.

• Recognize the Names: Look for names like Red 40 (Allura Red AC) and Red 3 (Erythrosine) and their corresponding E-numbers (E129 and E127).

• Be Aware of 'Natural' Options: Some products use carmine, or cochineal extract, a dye derived from insects, which is relevant for vegans and those with allergies.

• Look Beyond Red Products: Red dye can be used to achieve other colors and is often found in non-red items, so checking the label is always necessary.

• Seek Organic and Whole Foods: Choosing USDA-certified organic products or prioritizing unprocessed, whole foods guarantees they are free of artificial dyes.

• Understand Label Order: Ingredients are listed by weight, meaning a dye appearing higher on the list indicates a higher concentration in the product.

Understanding Common Artificial Red Dyes

Artificial food dyes, often derived from petroleum, are added to foods to enhance their appearance. The most common artificial red dyes in food are Red 40 and Red 3. While the FDA has banned Red 3 for use in food, products containing it may still be available until 2027. These dyes can appear under different names on ingredient lists.

• Red 40 (Allura Red AC): A widely used synthetic, petroleum-based dye known for its stable red color.

  • Common names: Allura Red AC, Red 40 Lake, FD&C Red No. 40, E129.
  • Found in: Sports drinks, sodas, cereals, condiments, baked goods, and candies.

• Red 3 (Erythrosine): A cherry-red coloring traditionally used in candies and maraschino cherries. Its use is being phased out due to potential health concerns.

  • Common names: Erythrosine, FD&C Red No. 3, E127.

The #1 Method: Mastering Food Labels

Reading the ingredients list on a product label is the most reliable way to identify red dye in food. Food regulations require color additives to be listed, though names can vary by region.

Here’s what to look for:

• The Ingredients List: Check the list, usually on the back or side of packaging. Ingredients are listed by weight, so items higher on the list are present in larger amounts.
• Specific Names: Look for terms like “Red 40,” “Allura Red,” or “Red 3”. Red dyes can be used to create colors other than red.
• E-Numbers: In many countries, E-numbers identify color additives. Red 40 is E129, and Red 3 is E127.

What About 'Natural' Red Dyes?

Some red colorants come from natural sources, such as carmine, which is derived from insects.

• Carmine (Cochineal Extract): A vibrant red dye made from crushed cochineal insects.
  • Common names: Cochineal extract, carmine, carminic acid, Natural Red 4, E120.
  • Found in: Juices, yogurts, candies, and ice cream.
  • Considerations: Not suitable for vegans and vegetarians and can cause allergic reactions in some people.
