Antioxidant Capacity of a Turkish Traditional Alcoholic Drink, Raki

Raki is an aniseed flavoured traditional Turkish alcoholic drink. Antioxidant capacity of raki samples from different commercial brands were evaluated by CUPRAC, DPPH, TEAC and ORAC assays and correlations between these assays and total phenolic content were also investigated. Additionally, the one-way ANOVA and Bonferroni tests were performed to compare differences between values of the samples. Results indicated that different raki samples exhibited different antioxidant capacity and total phenolic content. The mean antioxidant capacity values of samples were in the order of: ORAC>TEAC>CUPRAC>DPPH. The correlations of total phenolic content of samples with their CUPRAC, TEAC and ORAC results were found statistically significant, while DPPH assay showed no significant correlation.
