Raspberry Antioxidants

Red Raspberries and Antioxidants

The Oxygen Radical Absorbance Capacity (ORAC) measure the antioxidant activity of foods. Specifically, ORAC measures the time it takes to prevent an oxidation reaction. Antioxidants inhibit oxidation which is known to have a damaging effect on tissues.

Health research indicates that people who consume a diet rich in fruits and vegetables with a high ORAC values may slow the aging process. The ORACfl (umoleTE/g) analysis, which utilizes Fluorescein as the fluorescent probe, provides a measure of the scavenging capacity of antioxidants against the peroxyl radical, which is one of the most common reactive oxygen species (ROS) found in the body.

Trolox, a water-soluable Vitamin E analog, is used as the calibration standard and the ORAC result is expressed as micromole Trolox equivalent(TE) per gram.
