Description
A solvent‑based extraction that isolates carminic acid from dried cochineal insects for use as a natural red colorant.
Technical
The process crushes dried cochineal insects and extracts carminic acid in water at 60–80 °C for 1–2 h, optionally adding ~50 % ethanol to boost yield. Maintaining the extraction pH at 4–5 preserves pigment stability, after which the filtrate is concentrated under reduced pressure (40–50 °C) to obtain a dry powder or liquid concentrate.
