Evaluation of Peel, Pulp and Juices of Citrus Fruits for Vitamin C Content, Antioxidant and Antibacterial Activity

Abstract Citrus fruits like Sweet Orange, Malta, and Lemon are extensively cultivated in India. This research aims to analyze the vitamin C, antioxidant, and antibacterial activities of these fruits. Aqueous extracts from the peel, pulp, and juice of these fruits, along with samples stored at 4°C, were prepared for analysis. The DPPH method was employed for antioxidant assessment, antibacterial properties were evaluated using the Agar well diffusion method, and vitamin C content in juices was estimated pH-metrically.
The results from the DPPH method indicated that storage at lower temperatures reduced antioxidant properties. All fruit juices exhibited higher antioxidant activity compared to their peel and pulp counterparts. Orange juice demonstrated the highest antioxidant activity, followed by Malta peel. Lemon juice was found to have the highest vitamin C content.
None of the extracts exhibited antibacterial properties against Pseudomonas, Streptococcus pyogenes, Klebsiella pneumoniae, and Bacillus cereus. The study suggests that orange juice is the most potent natural antioxidant among the selected citrus fruits. A mixture of all fruit juices exhibited synergistic effects, while combinations of any two juices showed antagonistic effects.
