Natural concentrate of 100% dry raisin extract, under vacuum, at a maximum temperature of 45oC, Color golden to dark brown. Thick liquid with a sweet taste and aroma of raisins.

Stafidin is the syrup of raisins and is used in baking, confectionery and winemaking.

The characterization of the composition and the assessment of the antioxidant capacity of staphidine was extensively studied at the Laboratory of Pharmacognosy and Chemistry of Natural Products at the Department of Pharmacy of the University of Patras in Rio by researchers Konstantinos Zahari-Angelopoulos and Fotini N. Lamaris.




The total of phenolic components was estimated by the Folin-Ciocalteu method, while the determination of flavonoids by a colorimetric method using AlCl3. The estimation of sugar content was done with the colorimetric method of anthrone.

Then the phytochemical composition analysis of staphidine was further done. The researchers identified quercetin and kaempferol, glucose, sucrose, fructose and valine.

The results of this study showed that the colorimetric analyzes had a high content of sugars but also a high polyphenolic content which is almost ten times that of raisins.

According to them, the antioxidant capacity appeared extremely high, while staphidine also reduced peroxidation by 83%. This means that staphidine is of high nutritional value and an excellent antioxidant for the body, and for this reason, the researchers said, it is indicated for further study.
