Antimicrobial potential of pomegranate peel: a review

Abstract

Pomegranate peel (PoP) is a byproduct of the fruit juice processing industry, comprising nearly 30-40% of fruit portion. PoP is rich in polyphenols (phenolic acids, tannins and flavonoids particularly anthocyanins) which are known to have diverse biological functions including effectiveness against pathogenic microorganisms. PoP has shown a broad spectrum antimicrobial activity (AMA) of PoP against both Gram-positive and Gram-negative bacteria. It also presented promising AMA against antibiotic resistant microbial strains such as methicillin-resistant Staphylococcus aureus. The high levels of polyphenols, particularly punicalagin and ellagic acid, present in PoP have been responsible for its antifungal properties. PoP is effective against many fungi including both pathogenic (Aspergillus flavus) and opportunistic pathogens. These activities of PoP may be exploited as a phytomedicine for humans, in order to eliminate the use of antibiotics and reducing their cost. This review provides collective up-to-date information on the efficacy of plant-derived AMA of PoP.Pomegranate peel antimicrobial activity B. Singh et al. 960

Phenolic compounds in potato (Solanum tuberosum L.) peel and their health‐promoting activities

“…Therefore, the extraction of antioxidants from PPW has drawn much attention among the scientific community (Singh & Saldaña, ; Wijngaard et al ., ; Alvarez et al ., ). Phenolic acids possessing antioxidative activity are recoverable from the PP waste and can be utilised for value addition in the processed foods (Singh et al ., ). Moreover, the utilisation of wastes as resources make environment greener and healthy.…”

Combined Effect of Spirulina Platensis and Punica Granatum Peel Extacts: Phytochemical Content and Antiphytophatogenic Activity

“…Šavikin et al reported that pomegranate peel exhibits high levels of free radical scavenging activities and strong antimicrobial activity due to its phenolic content [9]. Several studies reported the efficacy of extracts from pomegranate peel to inhibit both Gram-positive and Gram-negative bacterial growth such as foodborne pathogens, spoilage bacteria and human pathogens [10]. It was reported as well that pomegranate extracts display antifungal properties [11].…”

Sensory, Tribological, and Rheological Profiling of “Clean Label” Starch–Lipid Complexes as Fat Replacers

“…[17][18][19] Starch-lipid complexes have some desirable functionalities in food systems. Singh and Byars [20] reported no occurrence of syneresis in yoghurt samples stored at 4 C when starch-lipid composites were used to replace milk solids in the production of low-fat yoghurts. Modification of maize and teff starches with stearic acid reduced the process of retrogradation in the resultant paste during cooling and storage.…”

“…[21] The enclosed lipid molecules in the form of amylose-lipid complexes, contribute to the stability of the amylose helix conformation by restricting the mobility of amylose [22,23] and thus prevents the amylose from getting involved in retrogradation. [20] Amylose-lipid complexes have been classified as part of the resistant starch fraction and do have similar health benefits as dietary fiber. [24,25] This is because complexes that are formed are less easily degraded by α-amylase enzymes.…”
