“…Postharvest vitamin C content of pomegranate is dependent on storage period and temperature (Kader, ). In current study, vitamin C content decreased during storage regardless of treatments (Figure b), also, a decrease in vitamin C was reported during cold storage periods (Arendse, Fawole, & Opara, ; Mphahlele, Fawole, Stander, & Opara, ). Vitamin C losses during storage were delayed by preharvest MeJA treatments and 2 mM MeJA was more effective than 1 mM (Figure b).…”

The fruit of pomegranate is bioactive compound source but is sensitive to low storage temperature. Methyl jasmonate (MeJA) spray on pomegranate trees was used in an attempt to evaluate its possible effect on fruit bioactive constituent changes and chilling injury (CI) incidence. Pomegranates trees were treated 15 days before harvest with distilled water or 1 and 2 mM MeJA, and then harvested fruit was stored at 4°C about 80 days. It was found that preharvest MeJA treatments improved arils color at harvest and reduced the postharvest CI index. Electrolyte leakage increased over storage, however, it was significantly higher in control rather than those treated. In addition, MeJA treatments significantly increased flavonoids, total antioxidant activity (TAA), total phenolics (TP), and total anthocyanins in comparison with untreated control. Practical applications The demand for pomegranate fruit is rising because of its special taste and unique bioactive constituents. Therefore, find out methods to store it and deliver in expanded time has commercial value. The common method to extend food life is low temperature but pomegranate shows chilling evidence when stored at low temperature. Several methods have been used to alleviate chilling. In current study, methyl jasmonate was sprayed on tree and its possible effect on fruit that stored at low temperature was assessed. The results revealed that MeJA might have potential preharvest application to reduce chilling, retain the quality and nutrition value in pomegranate arils by affecting the antioxidant systems.

This study was aimed at exploring biological properties of PoP for their potential use as an ingredient of choice in nutraceuticals and ethnic drug formulations. Pomegranate peel extracts (PoPx), derived from hydro-alcoholic extracts were evaluated for antioxidant, antimicrobial and potential antiulcer properties. Higher levels of total phenolics (427.19 mgGAE/g of extracts) recovered from hydro-alcoholic extracts exhibited significant (P < 0.05) ferric reducing antioxidant power (FRAP) and 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radicals scavenging activity. PoPx inhibited urease activity by 97.9% and IC50 for all extracts was estimated to be in a range of 30–44.4 μM. Potent inhibitory effects of PoP extracts were observed against Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhimurium and Aspergillus niger and minimum inhibitory concentration (MIC) was recorded between 0.25–0.89 mg/mL. The study indicates that PoPx of the white rind cultivar is a potential source of active biomolecules that could further be explored as a source of bioactive compounds and therapeutic agent against various ailments.\ud Practical Applications\ud \ud The findings of this study propose PoP of white rind cultivar as valuable waste of pomegranate juice processing industry. The proposed methodology for PoPx recovery and the bioactivities reported could equally benefit the processors for low cost recovery of protective biomolecules. The study further defines admissible levels of extracts being exploited by the industry for manufacturing nutraceuticals, functional food preparations and designing ethnopharmacological drugs of choice

“…In addition to the effects of postharvest factors such as storage conditions and packaging, the postharvest quality of pomegranate fruit is influenced by preharvest factors such as maturity status, climatic conditions, genotype and season. 12,13 Thus pomegranate fruit acceptability by consumers and processors depends on a combination of several attributes, including physical appearance (colour and size) and chemical constituents (sugar content, acidity and flavour). 14 The composition and concentration of chemical attributes have been of interest because of their important influence on sensory properties.…”
