Among the 11 fruits' pulps tested, acerola was the highest-scoring domestic fruit, meaning it had the most antioxidant potency, with a TEAC (Trolox equivalent antioxidant activity) score of 53.2 mg.
Oxygen radical absorbance capacity (ORAC) used to be an alternative measurement, but the United States Department of Agriculture (USDA) withdrew these ratings in 2012 as biologically invalid, stating that no physiological proof in vivo existed to support the free-radical theory.
