“…Citrus grandis L. Osbeck, locally known as Robab Tenga in Assam (Pomelo in English) belongs to the family Rutaceae, which is widely cultivated in Northeast India and also readily available in sub-Himalayan foothills. Along with the food values, it also has some medicinal properties with antioxidant activity and higher flavonoid, ascorbic acid and polyphenol contents, which may play crucial role in reducing metal salts into stable metal nanoparticles [8][9][10][11]. On the other hand, growing antibiotic resistance among microbes due to their frequent use emerges itself as an issue of global concern.…”

Biogenic silver nanoparticles (AgNPs) were synthesized by using Citrus grandis (L.) Osbeck fruit extract through a simple one step method by reducing silver nitrate (AgNO 3) at room temperature. Citrus grandis (L.) Osbeck is an indigenously available edible citrus fruit tree in Northeast India and sub-Himalayan foot hills. Formation of AgNPs were confirmed primarily by UV-Vis spectrophotometer and extensively characterized by TEM and XRD. The plasmon resonance at 435 nm confirmed the formation of AgNPs and TEM analysis showed AgNPs with average size of 11 ± 3.57 nm. XRD analysis showed crystalline nature of the Ag NPs with fcc lattice points attributed to (111), (200), (222) and (311) planes. The AgNPs showed excellent antimicrobial activities against both Gram positive (Bacillus cereus) and negative (Pseudomonas syringae pv. syringae) plant pathogens. It exerted MIC value of 20 and 30 µg/mL, respectively against B. cereus and P. syringae pv. Syringae, whereas MBC value of 70 and 80 µg/mL were observed against B. cereus and P syringae pv. Syringae, respectively. The Ag NPs showed no considerable cytotoxicity against murine macrophage RAW264.7 cell line which indicates its further possible application for animal model trial.

“…Citrus fruits are considered one of the most grown crops worldwide, including Jordan, with high nutritive and health values. The health benefits of citrus fruits have been attributed mainly to the presence of antioxidants such as phenolics and ascorbic acid (Kumar, Lamers, Singh, Ladaniya, & Sthapit, 2015). Jordan environment is rich and there is diversity in the Jordanian crop production (Qura'n, 2010).…”

Citrus fruits are considered one of the most grown crops worldwide including Jordan with high nutritive and non-nutritive value. The consumption of foods that contain natural antioxidants is thought to be an efficient way for reducing the risk for oxidative stress diseases. Determination of antioxidant content and capacity allows the screening of plants that are probably involved in the prevention and/or treatment of oxidative stress diseases. This study aimed at comparing four fresh Jordanian citrus fruits (namely: orange, lemon, pomelo, and mandarin) for their antioxidant content (using two methods namely: Folin-Ciocaltaeu method and total flavonoids method) and capacity (using two methods namely: 2,2-diphenyl-picrylhydrazyl (DPPH) and cupric antioxidant reducing capacity (CUPRAC) assays). Three solvents were used for the fruit extraction (ethanol, methanol, and water). There were significant (P < 0.05) differences between the fruits in terms of antioxidant content and capacity. Regardless of the extraction solvent, the fruit content of total polyphenols (M catechin/100 g) was as follows: lemon > mandarin > pomelo > orange. The total flavonoid content (mM rutin/100 g) of the fruits was: orange > mandarin > lemon > pomelo. On the other hand, the antioxidant capacity (M trolox/100 g) of the fruits was: lemon > mandarin > orange > pomelo. The antioxidant capacity (measured as mg vitamin C/ml extract) of the fruits was: mandarin > orange > pomelo > lemon. Different extracts of different fruits showed significantly (P < 0.05) different antioxidant contents and capacities. No correlation between antioxidant content and antioxidant capacity of the studied fruits has been found.

Disinfectant of pummelo (Citrus Grandis L. Osbeck) fruit juice using gaseous ozone

This work studied the effectiveness of gaseous ozone disinfection on pummelo (Citrus Grandis L. Osbeck) fruit juice components. Unfiltered and filtered pummelo fruit juices were treated with gaseous ozone for up to 50 min with ozone concentration fixed at 600 mg/h. A microbiological and physicochemical properties analysis were conducted on the ozone-treated fruit juices samples. It was found that the survival rate of aerobic bacteria, yeast and mold in unfiltered pummelo fruit juice were higher compared to filtered juice, as the juice components acted as protective barriers to the microorganisms. The microorganisms' inactivation in pummelo fruit juices was also observed to have increased as the ozone treatment time increased. Significant effects on total colour difference, ascorbic acid content, and total phenolic content were also observed over increased ozone-treatment time. However, ozone was shown to be ineffective in activating PME activity in both types of juice. The experimental results of this study indicated that pummelo fruit juice components had significant effects on the effectiveness of gaseous ozone, however, the degree of the effects depends on the different fruit components (total soluble solids, total phenolic content). As a conclusion, filtered juice showed better quality characteristics in comparison to unfiltered juice post-ozone treatment.
