What You Need to Know
The process relies on thermally assisted solvent extraction of bixin and norbixin from Bixa orellana seeds into lipid media at 60–80 °C, where heat increases carotenoid solubility while preserving their conjugated double‑bond system. Subsequent acidification (5–10 % vinegar) protonates residual pigments, lowering their oxidation potential and forming a stable emulsion that retains color and flavor during a brief simmer.
