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.
