Proximate Composition, Minerals Content, Antibacterial and antifungal Activity Evaluation of Pomegranate (Punica granatum L.) Peels Powder

Abstract

3 Abstract: The study on the proximate composition, minerals contents, antibacterial and antifungal activities of the most popular consumed fruit Pomegranate (Punica granatum L) peels has been carried out using recommended method of analysis. The result of the analysis shows that the moisture content (04 ± 0.22%), ash (05 ± 0.14%), fat(9.4 ± 0.1%), pH(3.75 ± 0.2), TSS (0.7 ± 0.04%), acidity (4.86 ± 0.5%), crude fiber (21 ± 0.6%), Total sugar (31.38 ± 0.3%), Reducing Sugar (30.40 ± 0.11%), Non-Reducing sugar (0.98 ± 0.12%), Nitrogen (1.395 ± 0.30%) and Protein (8.719± 0.10%). The minerals content were determined by analyzing the samples for sodium, potassium, iron, manganese and zinc ppm values were 1100 ±0. 4, 10000 ±0. 6, 60.5 ±0. 2, 4.5 ± 0.8 and 4.0 ± 0.65 respectively. Among the selected bacterial and fungal cultures, the highest antibacterial activity was recorded against Klebsilla pneumoniae and among fungi high activity against Aspergillus parasiticus was recorded. The peel extract were shown no activities against Salmonella typhi, Bacillus cereus and Aspergillus flavus.
