Blue #1 And Vegetable Annatto Color

Blue #1 is a synthetic blue dye made from petroleum. Annatto is a natural colorant extracted from the seeds of the achiote tree (Bixa orellana), which provides yellow to orange hues. When combined, they are used to create specific color shades in food products.

These ingredients are added to foods primarily as color additives. Blue #1 provides a vibrant blue, while annatto contributes yellow or orange. Together, they can create various colors, often found in products like ice cream and frozen yogurt to achieve desired visual appeal.

Blue #1 is an FDA-approved color additive. However, in April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue #1. JECFA has evaluated Blue #1 and set an acceptable daily intake. Annatto is also an FDA-approved color additive, and JECFA has evaluated it and set an acceptable daily intake. Some individuals may experience mild allergic reactions to annatto.
