title: Total Phenolic Content and Antioxidant Capacity of Polish Apple Ciders.
abstract: The total phenolic content and antioxidant capacity of three apple ciders produced in Poland were examined. The total phenolic content was determined by the Folin-Ciocalteau method and results were expressed in gallic acid equivalents with range from 0.21±0.003 to 0.30±0.004 mg/ml and Trolox equivalents ranging 0.88±0.012 to 1.24±0.015 mg/ml. The antioxidant activity was estimated by two methods: 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay with results expressed as EC50(ml/assay) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid method with results expressed as Trolox equivalent antioxidant capacity. The antioxidant properties of tested ciders were correlated with total phenolic content. Additionally, the correlation between 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid and 2,2-diphenyl-1-picrylhydrazyl radical scavenging methods was estimated.
