Antioxidant (ORAC) Value of Various Cod Liver Oils

Antioxidant (ORAC) Value of Various Cod Liver Oils

Cod Liver Oil Fish

USDA researchers have developed a new laboratory test to measure the oxygen radical absorption capacity of different foods and natural substances.  Known as the ORAC scale, it is one of the most sensitive and reliable methods for measuring antioxidant capacity.

ORAC, short for Oxygen Radical Absorbance Capacity, is a test tube analysis that measures the total antioxidant power of foods and other chemical substances.

Comparison ORAC values for a number of food items, prepared by the US Department of Agriculture and published in November 2007. 

All antioxidant capacity measurements for ORAC values are reported in mol of Trolox Equivalents per 100 grams (molTE/100 g).

The study below was lead by Dr. Vicki Schlegel Ph.D, Analytical Laboratory Supervisor, Associate Professor Department of Food Science and Technology University of Nebraska - Lincoln

The especially high ORAC antioxidant values found in the GPP samples are natural, from the sea and fermentation process.  The four other brands add an antioxidant preservative as part of product blend and may be part of their corresponding values.
