Assessment of some Australian red wines for price, phenolic content, antioxidant activity, and vintage in relation to functional food prospects.
J Food Sci 2011 Nov-Dec; 76(9):C1355-64JF

Abstract

Twenty-three Cabernet Sauvignon wines from the Mudgee region and thirty-two Shiraz wines from the Hunter Valley region were analyzed for phenolic content and antioxidant activity. Concentrations of (+)-catechin, quercetin, and transresveratrol, total phenolic content, and DPPH antioxidant activity varied considerably, both within and between varieties. Individual phenols, total phenols, and antioxidant activity were correlated with price and vintage. Shiraz wines showed positive and significant correlations for catechin and quercetin concentrations with total phenols, antioxidant activity, and vintage; and for total phenols and antioxidant activity with vintage. Cabernet Sauvignon wines showed positive and significant correlations for quercetin concentration with total phenols and antioxidant activity. There was a negative and significant correlation found between price and antioxidant activity for Cabernet Sauvignon wines. Results are discussed in terms of the potential for wine to be considered a functional food.

PRACTICAL APPLICATION

We report on potential health benefits (antioxidant activity) of 55 wines typical of 2 geographically close, but distinct, wine regions of Australia. Our results highlight the variability in functional components as an issue that needs further research and consideration in relation to wine as a functional food. The price of studied wines is not reflective of their health functionality, based on antioxidant activities.
