Effects of a wide variety of antioxidants and related compounds on the stability of betanine were measured in air‐saturated solutions at 40°C pH 5.0. No phenolic or sulfur‐containing antioxidant was effective in stabilizing the pigment. Ascorbic and isoascorbic acids had similar effects in improving betanine stability in a citrate buffer. When citric acid was combined with ascorbic acid, the antioxidant effect was no greater than when ascorbic acid was used alone.
