“…However, PFE in the study of Hasan Khan (2018) was not found to induce the inhibitory activity against tested bacteria which could possibly be ascribed to the pomelo variety or maturity stage. Besides, S. typhimurium, and P. aeruginosa were found to be highly susceptible to the treatment that was in agreement with previous reports(Aydeniz Günes ¸er et al, 2018;Tawfik, Al-Haliem, & Al- Ani, 2010;Van Hung, Yen Nhi, Ting, Lan Phi, & Al Loman, 2020).…”

The pomelo flavedo extract (PFE) from the pomelo peel (an agricultural waste) is well known with many functional properties. In this study, the incorporation of PFE into the bio-based polymer (pectin) for the formulation of the coating film was generally developed. The PFE showed a very high inhibitory effect against Pseudomonas aeruginosa (9.22 ± 0.37 mm of inhibition zone diameter), whereas Escherichia coli was found to be resistant to the PFE treatment. The incorporation of varying PFE contents into the pectin film with glycerol as a plasticizer for developing PFE-Gly-Pectin composite film and its effect on the film performance was investigated. PFE was found to reduce the swelling degree and increase the solubility of the Gly-Pectin film as well as increase the flexibility of the resulting film. However, the molecular structure, structural morphology, and contact angle of the Gly-Pectin film were insignificantly affected by the presence of PFE. The composite film at the PFE:Pectin ratio of 3.4 g/g was selected for the preliminary preservation of jackfruit bulbs which was stored at ambient temperature. As a result, coated jackfruit bulbs appeared to maintain a better quality after 3 days with an alleviated change in weight loss, color parameters, and total soluble solids, whereas the uncoated jackfruits showed signs of spoilage on Day 2 of the storage period. Therefore, the PFE conjugated pectin film suggested potential in the preservation of food materials.

The flavonoids are compounds synthesized by plants, and they have properties such as antioxidant, anticancer, anti-inflammatory, and antibacterial, among others. One of the most important bioactive properties of flavonoids is their antioxidant effect. Synthetic antioxidants have side toxic effects whilst natural antioxidants, such as flavonoids from natural sources, have relatively low toxicity. Therefore, it is important to incorporate flavonoids derived from natural sources in several products such as foods, cosmetics, and drugs. For this reason, there is currently a need to extract flavonoids from plant resources. In this review are described the most important parameters involved in the extraction of flavonoids by unconventional methods such as ultrasound, pressurized liquid extraction, mechanochemical, high hydrostatic pressure, supercritical fluid, negative pressure cavitation, intensification of vaporization by decompression to the vacuum, microwave, infrared, pulsed electric field, high-voltage electrical discharges, and enzyme-assisted extraction. There are no unified operation conditions to achieve high yields and purity. Notwithstanding, progress has been achieved in the development of more advanced and environmentally friendly methods of extraction. Although in literature are found important advances, a complete understanding of the extraction process in each of the unconventional techniques is needed to determine the thermodynamic and kinetic mechanisms that govern each of the techniques.

“…In the experiment, the antioxidant activity did not correlate with the enzyme concentration. Van Hung et al, [20] reported the antioxidant activity of pomelo peel powder, using enzyme-assisted powder with water extraction over 60 min. It showed a lower DPPH scavenging ability compared with this study at any concentration (28.6% ± 1.1%).…”

The purpose of this study was to evaluate the antioxidant, antibacterial, and anti-UVB of three kinds of fermented fruit peel extracts by pectinase enzyme, including pomegranate, pomelo, and banana peel. The antioxidant was evaluated by the DPPH (2,2-Diphenyl-1-picrylhydrazyl) free radical scavenging method. Antibacterial activity against Escherichia coli and Staphylococcus aureus was assessed by disk diffusion assay, and the photoprotective activity was measured using a photospectrometric method. The results revealed that pomegranate peel extract at 3000 IU/g peel exhibited potent free radical scavenging property against DPPH, with the smallest IC50 value at 0.18%, which was better than that of pomelo peel extract at 55.79%. Furthermore, the results suggested that the pomegranate peel extract also exhibited antibacterial activity against E. coli better than pomelo peel extract, but none of the three samples shows the antibacterial capacity against S. aureus. Moreover, 10% pomegranate peel extract also expressed the strongest anti-UVB activity, with an SPF value of 36.582. The research demonstrates pomegranate peel’s bioactivity potential for further experiments.
