A preparation rather than a single compound
Cochineal red complex is formulated for a specific colour strength and stability, so buyers specify carminic acid content and shade rather than the raw material name.
Colour shifts with pH
It is red at acid pH and shifts toward purple as pH rises, so the target pH of the product determines the shade achieved and the dose needed.
Typical Applications
- Dairy desserts and yogurt — 20-60 ppm for a stable pink.
- Beverages — 10-50 ppm at acid pH for a clear red.

Why did my shade change?
pH shift. It is red below pH 5 and purple above pH 7.
Is it heat stable?
Yes, which is the main advantage over natural alternatives.
