The most stable bright red
Allura Red holds its shade through pasteurisation, light exposure and long shelf life better than most alternatives, which is why it remains widely used in beverages despite the warning requirement.
Replacing it is not straightforward
Natural reds such as carmine and beetroot either carry allergen concerns or fade faster, so reformulation usually accepts a shorter colour life or a different shade.
Typical Applications
- Red beverages and cordials — 10-30 ppm for a stable red.
- Confectionery — 20-40 ppm in combination with other colours.
