What the label is naming
Red 3 is erythrosine, also E127. It has historically shown up in candies, baked decorations, and maraschino-style cherries. The catalog records the printed name only and does not track regulatory status as a verdict.
Where it hides
Cherries in syrup, cake decorations, and older candy formulas. Many red foods use Red 40 instead. Both can appear, and each is highlighted on its own span.
