The original ORAC assay (analysis) method uses several substances to analyze the antioxidant potential of a food, like Goji berry, usually comparing foods by weight (100g). Because of interference, masking of a food by the extracting (chemical) agents used to analyze antioxidant potential, a falsely low ORAC value can be derived when testing dry Goji berries using the common assay method, according to Brunswick Laboratory, the company that helped developed the ORAC assay.
A preferred and possibly superior method of ORAC testing is an analysis of the water of soaked Goji berries (Scientific Certification Systems, Inc.). Since water has no known antioxidant make-up, any antioxidants found in such water, after soaking a food, will give a truer picture of the food being analyzed. Using this method, Extreme Health’s wildcrafted Tibetan Goji Berry, has a documented result of over 36,000 ORAC units per liter; and, over 13,500 ORAC units per 100g of dry berries tested.
Why is ORAC important?
An ORAC unit (oxygen radical absorbance capacity scale) is defined as a measure of the ability of antioxidants to absorb oxygen “free radicals” in the body. The ORAC assay integrates the strength and duration of antioxidant protection for a product into a single numerical value, and has been shown to highly correlate with the level and the time of protection in cells, body tissues and blood levels. There is a near perfect correlation between the ORAC value and the antioxidant and immune system protection in the body.
So ORAC is important because it is an indication of a foods ability to provide the body and blood with immune enhancing factors (antioxidants) that combat oxidizing (rusting) of the bodies cells, membranes, and tissues; in a word – anti-aging potency.
