Antimicrobial Activity of Pomegranate Peel and Its Applications on Food Preservation

Table 1

Antibacterial effects of pomegranate peel against different pathogens.

Bacteria	Peel preparation and dose	Mechanism of action	Reference
Eight different food contaminants/pathogenic bacteria	Under high pressure at 300 MPa	Due to high antioxidant activity and high total phenolic content	[13]
B. coagulans, B. cereus, B. subtilis, S. aureus, E. coli, K. pneumoniae, and P. aeruginosa	10 g sample (sample = 10 g peel extracted with 250 ml 80% methanol) extracted with 100 mL water	Estimated to be a result of high phytocompounds including phenols, tannins, and flavonoids.	[29]
S. aureus and Salmonella	2, 4, 6, 8, 10, 12, and 14% PPE with 20% polyethylene glycol	Inhibition of films against targeted microorganisms	[42]
S. aureus	The ethyl acetate extract of pomegranate peel	Due to the high concentrations of tannins	[43]
Gram-positive and Gram-negative bacteria including E. coli, B. subtilis, E. aerogenes, S. marcescens, Brucella spp., S. cerevisiae, and R. glutinis.	Water extracts of pomegranate peels (50/100 w/v)	Due to high tannins content	[44]
