 Why
do you think your paper is highly cited?
There is considerable interest in the food and nutraceutical
industries regarding antioxidant capacity and appropriate
methods for determining antioxidant capacity in foods.
|
“...to develop standardized protocols for testing through multi-laboratory validation procedures.”
|
|
This paper presents, in review form, the advantages and
disadvantages of several analytical methods for determining
antioxidant capacity in foods and nutraceuticals, and the
justification for selecting two methods to develop standardized
protocols for testing through multi-laboratory validation
procedures.
Does
it describe a new discovery, methodology, or synthesis of
knowledge?
The manuscript describes a synthesis of knowledge that is
available relative to analytical methods for determining
antioxidant capacity.
Could
you summarize the significance of your paper in layman's terms?
The manuscript proposes the use of two different methods for
measuring antioxidant capacity: one, the Folin-Ciocalteu assay,
because of its simplicity and long history of use by analytical
chemists and the other, the oxygen radical absorbance capacity (ORAC)
assay, because of its relevance to human biology.
How
did you become involved in this research, and were any problems
encountered along the way?
We became involved in this research in 1996 when we were
contemplating studies of factors in the body which might impact
oxidative stress and antioxidant status. We realized that one of
the methods that we were using would likely have application to
measuring the antioxidant capacity in foods, and perhaps be more
useful than most of the existing techniques.
