Acai berry, freeze-dried

The antioxidant value of Acai berry, freeze-dried described in ORAC units is:
102,700 μ mol TE/100g.

The acai (açaí) berry is the fruit of the açaí palm, native to tropical Central and South America. The purple variety of acai berry most often used commercially was found to have the following levels of antioxidant activity: excellent against peroxyl radicals, good against peroxynitrite and poor against hydroxyl radicals. The assay for superoxide gave a value of 161,400 units per 100 g, the highest yet found for any plant evaluated to date. The total ORAC value against peroxyl radicals, determined from both hydrophilic and lipophilic sources, was 102,700 units per 100 g.

The ORAC value is expressed in micromoles of Trolox Equivalents per 100 grams of sample (this is the laboratory measure of ORAC).
