Green Apple Contains Yellow 5 & Blue 1

Yellow 5, also known as Tartrazine, is a synthetic yellow azo dye. Blue 1, also known as Brilliant Blue FCF, is a synthetic blue colorant. Both are widely used to add color to foods.

These synthetic dyes are added to foods to provide or enhance color, making products more visually appealing. They are commonly found in candies, beverages, baked goods, and frozen desserts like ice cream and frozen yogurt.

Yellow 5 and Blue 1 are FDA-approved color additives. The FDA has stated that Yellow 5 can cause hives in a small percentage of individuals, and some studies have suggested a link between artificial food colors and hyperactivity in children, though the evidence is mixed. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Yellow 5 and Blue 1. JECFA and EFSA have evaluated these dyes and established acceptable daily intakes.
