Citrus Fruit Peels in Combating Various Foodborne Pathogens
Journal Title: RADS Journal of Biological Research and Applied Science - Year 2018, Vol 9, Issue 2
Abstract
Foodborne diseases are the world's main problem in a society nowadays; many phytochemicals are of great interest to scientists. Herbal medicines can be used to treat many infectious diseases. In our study, we focus on screening of antibacterial activity of the lemon (Citrus limon) and orange (Citrus sinesis) peels against various pathogens. Bioactive compounds have been found in variety of citrus fruits that have favorable impact on human health. The major component; flavonoids have been found in the peels of citrus fruits in large amount. Citrus peel has a rich amount of flavonoid and other poly methylated flavonoids (exceptional to some plants). These antibacterial compounds exhibit antibacterial activity and have wide application in both food and pharmaceuticals industries. The citrus peel extracts show effective antimicrobial activity. The antagonistic activity of selected citrus peel extracts was determined by agar well diffusion; against test organisms i.e. Escherichia coli, Salmonella typhi and Bacillus subtilis isolated from food products. Effectiveness of peel extracts are measured in terms of inhibitory zones in millimeter. The methanol extract of lemon peel displayed zone of inhibition in between 5mm to 8mm and methanol extract of orange peel displayed zone of inhibition about 10mm and 11mm. It was observed that lemon peel extract has maximum antibacterial activity against Bacillus subtilis (8mm) and minimum antibacterial activity against Salmonella typhi (5mm) whereas orange peel extract has maximum antibacterial activity against Bacillus subtilis (11mm) and minimum antibacterial activity against Salmonella typhi (10mm). Both Citrus peels extract showed considerable antibacterial activity against all tested foodborne pathogens. Our main focus was the use of herbal treatments against various infections which overcome the emergence of upcoming superbugs.
