Abstract:
The article analyzes the global wines production and consumption in the period from 2000 to 2020. The authors studied the total antioxidant activity of 19 samples of red wine from the Old and New World. They found that in the studied red wine samples, the total antioxidant activity value was in the range from 8,408 to 19,249 mmol-eq/dm3 . In red Old-World wines samples, the total antioxidant activity values were in the range from 10.056 to 19.249 mmol-eq/dm3 , while the highest were in red wines produced in Italy from the grape varieties Nero di Troia, Corvina and Rondinella, as well as in French wines from the varieties Merlot and Cabernet Franc; the smallest antioxidant activity values were in Italian wines produced from varieties Cabernet Sauvignon and Spanish wines from the varieties Tinta Roriz, Turiga Nacional, Turiga Franca. In the studied samples of red New-World wines, the total antioxidant activity values accounted for the range from 8.408 to 16.456 mmol-eq/dm3 , while the highest values were for Australian wines produced from the Shiraz grape variety and American wines from the Merlot variety; the lowest indexes were for American wine produced from the grape variety Pinot Noir. In the red Russian wines samples, the total antioxidant activity values were in the range from 5.903 to 15.566 mmol-eq/dm3 , while the highest indicators were in the wine from the varieties Merlot and Cabernet Sauvignon produced by the manufacturer “Usadba Divnomorskoe”; the lowest figures were for the wine produced from the “Pinot Noir” variety of the same producer. The antioxidant activity of wines varied from 26.3 to 60.1 % of the recommended daily intake in terms of ascorbic acid (ascorbic acid AOA – (32.024 ± 0.350) mmol-eq/dm3 ). The researchers revealed that the antioxidant activity as an identification marker for French wines must be at least (15.0 ± 0.5) mg-eq/dm3 , for Italian wines – at least 16.5 mg-eq/dm3 , for wines from Cabernet Sauvignon grapes, possible deviation was 5 mg-eq/dm3 . For New-World wines and Russian wines, the antioxidant activity must be at least (10.0 ± 0.5) mg-eq/dm3 , for wines from Pinot Noir grapes, possible deviation was 2 mg-eq/dm3 .
