Abstract

Fruits health benefiting properties are because of their richness in vitamins, minerals, micro-nutrients, antioxidants etc., which helps the body prevent or at least prolong the natural changes that causes by the or during the disease process. Considering so many benefits of antioxidants, this study was designed to find out which fruit provide us with the highest levels of antioxidants. Since now-a-days majority of people prefer drinking commercially available fruit juices, this research will also focus on the comparison of the freshly extracted fruit juices with the commercially available fruit juices. The total amount of the antioxidants in different fruit juices were determined using two methods Ferric ion reducing antioxidant power assay and Phosphomolybdeum method. The results obtained showed that the antioxidants levels of freshly extracted fruit juices were higher when compared to commercially available juices. Also freshly extracted pomegranate juice exhibited the highest antioxidants when compared with other fruit juices.
