The polysaccharide based composite biomaterial (coating) used in preserving fruits and vegetables during storage is attracting increased attention as it is biodegradable material that prolongs shelf life. In the present investigation, chitosan–pullulan (50:50) composite edible coating was prepared with pomegranate peel extract (0.02 g/mL) as an active antioxidant agent. The effect of treatment with pomegranate peel extract enriched chitosan–pullulan composite edible coating on the shelf life of mango fruits during 18 days of storage period at room (23 °C) and cold (4 °C) temperature was evaluated. Results of the present study demonstrated that the application of chitosan–pullulan composite edible coating significantly (p ≤  0.05) influences the storage life of mango fruits at both storage temperatures. The chitosan–pullulan composite edible coating reduced the physiological loss in weight (PLW), and maintained total soluble solids (TSS), acidity and pH of coated mango fruits as compared to the control. In addition, fruit sensory quality such as freshness, color, taste and texture were also retained by the treatment. Furthermore, sustained firmness, phenolic content and antioxidant activity confirmed the effectiveness of the pomegranate peel extract enriched chitosan–pullulan composite edible coating on mango fruits. The phenolic, flavonoid and antioxidant activity of coated fruits were retained by pomegranate peel rich edible coating. Therefore, the chitosan–pullulan (50:50) combination with pomegranate peel extract can be used as an alternative preservation method to prolong the shelf life of mango fruits at room and cold storage conditions. However, more in-depth studies are required at farm and transit level without affecting the postharvest quality of mango fruits, providing more revenue for farmers and minimizing postharvest losses.

ABSTRACT The effects of methanolic pomegranate peel extract (MPPE) on the quality of gutted rainbow trout (Oncorhynchus mykiss) were examined periodically during 6 months of storage at −18°C. Fresh samples were dipped (ratio of fish to liquid, 1:2 [wt/vol]) in sterile water or in sterile water containing 1, 2, or 4% (wt/vol) MPPE and packed in low-density polyethylene pouches. The control and treated samples were analyzed monthly for microbiological, chemical, sensory, and textural characteristics. Microbial growth in samples was significantly reduced by MPPE treatment (P < 0.05). Smaller increases in the values for total volatile base nitrogen, peroxide, and thiobarbituric acid–reactive substances and better oxidative stability were also obtained. Moreover, higher organoleptic scores were recorded. However, regarding the general acceptability, the highest score was achieved in the 1% MPPE group. Greater hardness and chewiness were obtained with 4% MPPE (P < 0.05). Therefore, dipping fish in MPPE can be considered an effective method to extend the shelf life and the overall quality of the product.

Fermented milk beverages supplemented with pomegranate peel extract and inoculated with Lactobacillus plantarum and Bifidobacterium longum subsp longum were produced. The antioxidant activity of fermented milk beverages supplemented with pomegranate peel 150 mg/L (FMPO 150) and 300 mg/L (FMPO 300) was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). In addition, the polyphenolic profile and sugars content were determined by HPLC analysis, and the volatile compounds were identified using GC-MS analysis. The effects of FMPO 150 and FMPO 300 (10 g/day) on the lipid profile and antioxidant/biochemical status of rats were also evaluated after 4 weeks of oral intake. Antioxidant activity of the fermented milk beverage FMPO 300 was higher than that of FMPO 150. GC-MS analysis of the volatile compounds revealed that diacetyl, acetoin, and acetaldehyde were the major constituents. FMPO 150 and FMPO 300 were efficient in reducing the LDL cholesterol and triacylglycerol and increased the HDL cholesterol in serum. Liver function biomarkers were not affected by the end of treatment (p<0.05). Also, the thiobarbituric acid-reactive substances (TBARS) were decreased, while the activity of antioxidant enzymes in the liver (GSH, CAT, SOD, and GPx) were increased. Hence, the combination of pomegranate peel extract and probiotic lactic acid bacteria in a fermented milk beverage provides not only probiotic benefits but also bioactive phenolic compounds that could be functional and possess therapeutic effects.

The effects of convection-oven precooking, frozen storage (−18 °C/ two months) and four different reheating methods—namely, boiling, pan-roasting, convection oven and microwave oven on pH, color, texture, antioxidant activity and warmed-over flavor of beef meatballs were investigated. In this study, four kinds of beef meatballs were prepared: with added butylated hydroxyl toluene (0.02% BHT, M1); with nutmeg extract (0.02%, M2); with nutmeg powder (0.02%, M3) and control (no antioxidant). Addition of (0.02%) nutmeg extracts in beef meatballs M2 resulted in a significant (p < 0.05) decrease in lipid and protein oxidation, hardness and gumminess values after convection oven precooking. Again, M2 reheated by microwave oven significantly (p < 0.05) reduced cooking loss, gumminess, springiness, rancid flavor, saltiness and burnt taste and increased oxidative stability, redness and adhesiveness with the chewiness intensity and overall acceptability compared to control, M1 and M3. Conclusively, the addition of nutmeg extracts (0.02%) as a natural plant antioxidant to precooked beef meatballs can result in reduced lipid and protein oxidation levels, stabilized color and texture values and improved overall acceptance after reheated by microwave oven during two months of frozen storage.

A novel antioxidant chitosan film incorporated with pomegranate peel extract (PPE) (0, 1%, 2%, and 3% (w/v)) was developed. The mechanical property, water vapor permeability, total phenolic content and antioxidant activity of the films were investigated. Fourier transform infrared (FTIR) spectra revealed that good interactions occurred between functional groups of chitosan with PPE. The flexibility and water vapor barrier property were improved by incorporation with PPE. Films containing PPE had higher total phenolic content and showed better antioxidant activity. These results suggest that chitosan films incorporated with PPE can be useful for meat preservation.

Background: Funcionalized multi-walled carbon nanotubes (ox-MWCNTs) were used for the preparation of therapeutic nanoparticles for delivery of some bioactive compounds. Consequently, this work deals with the preparation of grafted MWCNTs with n-vinyl caprolactam in the presence of pomegranate peel extract (P. granatum), titanium dioxide (TiO2) and/or silver nanoparticeles and their toxic effects on male mice using in vivo biological examination (liver and kidney dysfunction biomarkers) and the histopathological analysis. Methods: P. granatum extract was immobilized onto functionalized MWCNTs using simple adsorption technique. Moreover, The prepared materials were analyzed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM). In vivo examination using liver and kidney dysfunction biomarkers was investigated. In addition, the histopathological study was carried out. Results: The ox-MWCNTs induced significant elevation in the liver enzymes including AST, ALT and ALP relative to the control group. While, the treatment with P. granatum extract only did not induce any change in the liver and kidney biomarkers. In other words, P. granatum extract loaded onto functionalized MWCNTs showed low effects on liver enzymes and kidney function biomarkers in the treated mice in comparison with ox-MWCNTs and extract separately. Moreover, histopathological analysis revealed that the P. granatum extract functionalized MWCNTs exhibited normal renal tissue with no histopathological alteration. Conclusion: The grafted MWCNTs with n-vinyl caprolactam in the presence of pomegranate peel extract (P. granatum), titanium dioxide (TiO2) and/or silver nanoparticeles were successfully prepared. SEM-micrographs showed complete coating of MWCNTs fiber with the extract. The prepared materials resulted in no toxic effects and the histopathological findings were confirmed by inflammation of the liver and kidney tissues.
