FAQ

Frequently asked questions.

What is Blue 1 made from?▾
Blue 1 is a synthetic dye, chemically produced in laboratories. Its origins trace back to petroleum and it does not occur naturally in any edible plants or animal products. It's specifically engineered for its coloring properties.
Which food products commonly use Blue 1?▾
Blue 1 is frequently found in beverages, candies, ice creams, cereals, and baked goods, especially those designed to be brightly colored. It's responsible for many of the intense blue shades seen in snack foods and desserts.
Would Nonna have used Blue 1 in her cooking?▾
Nonna would never have used Blue 1. Blue food coloring was simply not part of traditional Italian cuisine, and certainly not a synthetic, petroleum-derived chemical. Her kitchen relied on natural ingredients and colors.
