Abstract

In this study, the physicochemical properties and antioxidant activities of the commercially produced 15 pomegranate sour samples and one control sample were determined and their compliance with the TS 12720 (traditional sour pomegranate concentrate standard) was evaluated. Antioxidant activity values of pomegranate sours extracts were determined using 6 different methods. The samples had strong antioxidant capacity, except for N10 and N15. In addition, glucose, fructose, sucrose, HMF and acidity measurements of the same samples did not show compatibility with TS 12720. The pH values of the samples of N7, N8, N10, N11, N14 and N15 were not in accordance with the standard values (2.4-4.0) The titratable acidity values measured in samples of N1, N3, N4, N6, N10, N13, N15 were below the value (>6.0% (m/m)) in the standard. While the brix values of the samples were measured between 59.20-75.70, the brix values of the N12, N13 and N14 samples were determined below the standard brix value (>68%). The highest HMF value of the samples were determined as 8117.66. According to TSE 12720, the HMF content should be not exceed 50 mg/kg. However, the HMF values of the samples were detected above the maximum limit value except for N8 and N16.
