Μελέτη χημειοφωταυγειομετρικών μεθόδων σε ροή (FIA-CL) για εκτίμηση αντιοξειδωτικής ικανότητας αλκοολούχων ποτών

Study of chemiluminometric methods in flow injection analysis (FIA-CL) for the evaluation of antioxidant capacity of alcoholic beverages

In the present research work, a study of various chemiluminometric methods in
flow injection analysis (FIA-CL) was accomplissed in order to assess the
antioxidant capacity of alcoholic beverages. The antioxidant capacity of a
natural product is the ability to bind free radicals, particularly reactive
oxygen species. Phenolic compounds are among the most important antioxidants.
These compounds react with free radicals or reactive forms of oxygen and
protect our body from many diseases. Phenolic derivatives are found in
vegetables and in other products such as natural juices, alcoholic beverages,
etc.
The antioxidant activity of phenols has been estimated by various analytical
techniques, particularly spectrophotometric methods. In this context, four
methods of flow injection analysis via chemiluminescencent (FIA-CL) were
examined, optimized and applied. The first two methods are based on the
chemiluminescent reaction of luminol and lucigenin to various active forms of
oxygen. The other two methods are based on the reducing power, through which
the antioxidant activity of various substances was determined. Each method was
applied to standard substances and different alcoholic beverages (wine, beer
and spirits). The results were examined and compared.
