“…Our data is in contradiction with Cha et al findings who observed that the decreasing order of TPC and TFC in Korean Opuntia humifusa fruit was 80% ethanol > 80% methanol and 80% acetone (p > 0.05) whereas they are in [31,41,42]. Although alcoholic aqueous mixtures have been confirmed to be very effective for the extraction of high polyphenols and flavonoids, some recent studies proved that different combinations of acetone and water (50-80%) exhibited the highest values of TPC and/or TFC sometimes without any significance difference with their homologous alcoholic water mixtures [42][43][44][45][46][47][48].…”

Opuntia stricta the shrubby plant is naturally occurring in all parts of the world used as popular ornamental and is known to have medicinal properties due to its phytochemical compositions. In this study, the effect of solvents (80% ethanol, 80% methanol and 80% acetone (v/v) in water) on the extraction yield, total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity and antibacterial activity of Opuntia stricta fruit were investigated. For the antioxidant activity assay, three different in-vitro methods DPPH, ABTS and FRAP were followed. The One-way ANOVA calculations showed that the extraction solvents influenced greatly and significantly the TPC, TFC and antioxidant capacity. Overall, 80% ethanol showed highest percentage of extraction yield while 80% acetone extract showed the lowest extraction yield but the highest TPC, TFC and antioxidant activity of Opuntia stricta fruit. In addition, Pearson’s correlation analysis proved a strong correlation between TPC, TFC and all antioxidant methods used. The antibacterial tests demonstrated that 80% methanol and 80% acetone extracts exhibited the highest zones of inhibition (11.66 and 11.33 mm respectively, p > 0.05) against Salmonella thyphimurium. Likewise, the 80% acetone extract revealed the best inhibitory effect contra Escherichia coli (p > 0.05) with an inhibition zone of 11 cm. Unfortunately, it was observed that gram-positive bacteria were less sensitive to all Opuntia stricta extracts compared to the gram-negative bacteria.

“…Hence, these compounds could act as natural additives to food preservation and quality improvement, providing an alternative to synthetic antimicrobial and antioxidant use (Hygreeva et al, 2014; Karre et al, 2013; Oswell et al, 2018). Antibacterial effects of pomegranate peel extracts have been described in several studies (Sharayei et al, 2020; Singh et al, 2019), such as antimicrobial activities against Gram‐negative bacteria ( Escherichia coli , Enterobacter aerogenes and Pseudomonas aeruginosa ) and Gram‐positive bacteria ( Staphylococcus aureus , Listeria monocytogenes , Bacillus subtilis , Bacillus cereus and Enterococcus faecalis ), as well as against yeasts and fungi ( Aspergillus niger, Candida albicans , Fusarium oxysporum ) (Balaban, Koc, Sar, & Yesilcimen Akbas, 2021; Fawole et al, 2012; Malviya et al, 2014; Türkyılmaz et al, 2017). Besides, Bakkiyaraj et al (2013) and Balaban, Koc, Sar, and Akbas (2021) described pomegranate antibiofilm formation of S. aureus, E. coli, C. albicans, B. subtilis, B. cereus and E. faecalis .…”

As an agro‐food by‐product, pomegranate peel is a potential source of bioactive compounds with preservative properties. Ultrasound‐assisted extraction (UAE) is a green extraction method that is useful in increasing extraction yields and reducing extraction time without using toxic solvents. This study aimed to optimize the UAE of a pomegranate peel for its use as a preservative using water as the solvent, maximizing its antioxidant potential for its particular application to chicken burgers. A Box–Behnken design was applied using extraction time, extraction temperature, and ultrasound amplitude as independent variables. The response surface methodology (RSM) results showed that the highest concentration of the phenolic compound is obtained at amplitude—50%, temperature—38°C, and time—15 min. The extracts with RSM conditions at a concentration of 0.8% indicated that the extracted preservative exerts the ability to delay meat oxidation on days 1, 2, 4, and 7, even better than ascorbic acid. Practical applications The waste and elimination of agro‐industrial by‐products generate significant environmental impacts and critical economic losses. Today, a sustainable paradigm it seeks to add extra value to these by‐products by giving them a new application in the production chains, thus favoring the circular economy. The ultrasound‐assisted process is an excellent tool to obtain green compounds that cover the recent concern from the industry and consumers for healthier foods. In this case, the application of the pomegranate peel extract is presented as an alternative to synthetic preservatives due to its great antioxidant capacity.

In this work, seven different extracts from pomegranate (Punica granatum L., cv. Hicaz nar) peel were prepared by using different solvents (ethanol, methanol, either alone or in combination with acid, acetone and water). The phenolics (punicalagins and ellagic acid), organic acids (citric acid and malic acid) and sugars of pomegranate peel extracts were determined. The highest amounts of punicalagins and ellagic acid were detected by ethanol-acid extract as 13.86% and 17.19% (w/v) respectively, whereas the lowest levels were obtained with acetone and water extracts. Moreover, the methanol-acid (3.19% malic acid) and ethanol-acid (1.13% citric acid) extracts contained the highest levels of organic acids. The antimicrobial activities of extracts were investigated by agar well diffusion method. Methanol-acid and ethanol-acid extracts exhibited the highest antimicrobial effects on all tested microorganisms, giving inhibition zones ranging in size from 17 to 36 mm. Although similar antimicrobial activities were observed by ethanol, methanol, and acetone extracts (up to 24 mm), the lowest antimicrobial activities were attained by water extract (0-15 mm). All extracts were generally more effective against Gram-positive bacteria: Enterococcus facealis, Bacillus subtilis, Bacillus cereus than Gram-negative ones: Escherichia coli and Enterobacter aerogenes. It was shown that extracts from pomegranate peels represent a good source of bioactive compounds.
