Department of Agriculture (USDA) to remove
ORAC values from its website, leaving consumers questioning the true benefits of antioxidants and companies searching for a way to reliably measure antioxidant activity within the human body."
From a stock solution of DMSO, trolox (10 mmol x [L.sup.-1]) was diluted in
ORAC buffer solution to a concentration of 20 [micro]mol x [L.sup.-1].
(2002), the
ORAC technique can be used to evaluate the antioxidant activity in animal tissues, plant extract, natural products and foods.

Orac concludes: "If state right-to-try bills are basically symbolic rants against the FDA, the passage of a federal right-to-try bill would be a disaster for patients and the clinical trial process."
As with the anthocyanin concentrations previously reported, the
ORAC values recorded in this study (Figure 4) wines.
The accompanying chart shows berries pack a big antioxidant punch and tend to contain the highest
ORAC levels.
With the yield of total flavonoids and the value of
ORAC as the index, the ultrasonic power was 300 W, and the ethanol concentration, solid-liquid ratio, extraction time and temperature were changed in turn:
Moreover at least 10.000
ORAC as foods were prescribed in the dietary plan.
The LOX/RNO and
ORAC methods found in quinoa flour a remarkable antioxidant activity in the hydrophilic, lipophilic and free-soluble phenolic extracts-higher than that contained in durum wheat, although lower than that found in emmer hulled wheat.
