Description
Cuiqin Li and three colleagues extract purple pigments from black rice with a green solvent and ultrasound, in a 2026 study. The pigments fight oxidation and may help control blood sugar, but standard extraction yields are low.
Their recipe blends a choline-based solvent with lactic acid, plus water, and warms the mix with ultrasound. Tuned settings beat ethanol extraction by a clear margin, reaching about thirty-seven milligrams of pigment per gram of rice. The main pigment was confirmed as cyanidin-3-glucoside. Extracts from the new method fought oxidation harder and blocked two sugar-splitting enzymes more strongly. The authors propose the extract for supplements and natural food coloring.
