Title: Antioxidant and anti-virulence activity of pomegranate peel extract and their use in functional foods


Pomegranate peels (Punica granatum) are usually discarded as waste even a significant portion of polyphenols are often present in high concentrations in the outer parts of fruits. The objective of this study was to establish an extraction procedure for polyphenols and proanthocyanidins from pomegranate’s peels (PMP), and to assess their potential radical scavenging activity. The recovery of polyphenols and proanthocyanidins was the highest at 50°C for 20 min. The antibacterial activity was found to be dose dependent with an MIC value of 0.6 and 1.4 mg/ml for E. coli and Pseudomonas aeruginosa, respectively. The assay of E. coli adhesion carried out at MIC showed a reduction of up to 80% of the adhesion index accompanied with a reduction in motility and ornithine decarboxylation as indicated by MIO test. P. aeruginosa gelatinase and lecithinase activities were reduced by 40.28% and 53.84%, respectively. The extracted polyphenols were encapsulated by ionic gelation method using sodium alginate and pectin. Different microencapsulation parameters were studied to enhance the loading efficiency and the final microbeads were used for the preparation of functional milk. Results showed that 62.23% of polyphenols remained stable for 11 days in milk fortified with alginate-pectin (2:1) microbeads.
