Soy Lecithin And Yellow 5 Lake

Soy lecithin is a mixture of fats, called phospholipids, extracted from soybeans. It is a natural byproduct of soybean oil processing. Yellow 5 Lake is a synthetic food coloring, made from the petroleum-based dye Tartrazine (Yellow 5) combined with an insoluble metallic salt, usually aluminum hydroxide.

Soy lecithin acts as an emulsifier, helping ingredients like oil and water mix and stay blended, and also as a stabilizer. It is commonly found in products such as chewing gum, chocolate, and baked goods. Yellow 5 Lake is used to provide a yellow color to foods and beverages, especially in products like candies and chewing gum where color stability is important.

Soy lecithin is generally recognized as safe (GRAS) by the FDA, and JECFA has evaluated it without setting a numeric limit. Yellow 5 Lake is an FDA-approved color additive. JECFA has evaluated Tartrazine (Yellow 5) and set an acceptable daily intake. Some studies have suggested a possible link between synthetic food dyes and hyperactivity in some children, but the evidence is mixed. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5.
