A blue food dye from red algae is now approved for US food
What happened
US health regulators have approved a new blue color additive for food. This means food manufacturers can now use galdieria extract blue, derived from red algae, in various products.
Why it matters
For decades, the palette of natural food colors has been limited, especially for stable blues. This new approval expands the options for food companies looking to use natural ingredients. It could lead to more vibrant and naturally colored foods on grocery shelves.
The signal
Watch for new food products appearing with 'galdieria extract blue' on their ingredient lists, particularly in categories like candy, baked goods, and beverages.
