Brilliant yellow but light sensitive
Curcumin gives a bright, clean yellow that is hard to match naturally, but it fades in light and shifts to orange above pH 7. Packaging and pH control are part of using it successfully.
Dispersible grades make the difference
Native curcumin is barely water soluble. Commercial grades are emulsified or dispersed so they can be dosed into aqueous products without ringing or precipitation.
Typical Applications
- Yellow beverages and dairy — 10-50 ppm in acid systems with opaque packaging.
- Confectionery and snacks — 20-100 ppm for yellow shades.
Frequently Asked Questions
Why does my yellow fade?
Light exposure. Use opaque packaging and an encapsulated grade.
Does it work above pH 7?
It shifts to orange-red and loses brightness, so it suits acid products better.
Does it taste of turmeric?
At normal dosage no; high doses carry a spice note.
