Experimental Analysis of Anaerobic Co-digestion: Potential of Fruit Wastes

This study focuses on converting fruit waste into usable clean energy by an innovative, cost-effective anaerobic biodigester. The biodigester is designed to anaerobically digest various fruit wastes and starter inoculums of cow dung that are locally obtained. A batch vertical digester of 1000 liters capacity built of fiber with a phonematic agitator positioned in the center is used to improve mixing. The retention time is 30 days with a substrate of banana peels co-digested with mango and papaya peels individually in the ratio of 50:50. The combined wastes generated the biogas and the total quantity of biogas generated for all combined wastes over 21 days varies between 530L/day and 480L/day respectively. In this work, banana and mango peel (waste/water) split 50:50 gives a peak yield of 530L/day. The average ambient temperatures are kept in the range of 25°C to 35°C (i.e., mesophilic range). The pH range of 6.4 to 7.8 is consistently maintained and seems to be stable. Therefore, this proposed anaerobic digester would reduce the disposal of solid waste, and it is cost-effective. After cleaning, it is observed that the combined peels of bananas and papaya contained 91.95% of the estimated biogas and methane, which can be used to solve energy issues such as electricity production and cooking purposes.

Mango (Mangifera indica) seeds and peel-derived hydrocolloids: Gelling ability and emulsion stabilization

Mango is a tropical fruit that is consumed worldwide and is distinguished by its sweet and juicy flesh. Unfortunately, the peels and seeds of mango fruit are often discarded despite the fact that they contain compounds that can be valorized for certain applications. In this study, a physicochemical and hydrodynamic characterization of hydrocolloids extracted from the peel and seeds of mango fruit was performed and the impact on the microstructure and rheological behavior of derived gels, as well as the ability to form emulsions, were analyzed. The physicochemical parameters and proximate compositions of the different samples showed that the hydrocolloids extracted from the seeds are rich in proteins whereas those from the peel are rich in carbohydrates. The molecular weights calculated from the hydrodynamic characterization (Mv) are 101515 g/mol and 102,580 g/mol for hydrocolloids extracted from the peel and seeds, respectively. Dispersions of these hydrocolloids in water produced hydrogels upon heating, which exhibited a shear thinning response that can be described by the Williamson model. The ability of these hydrocolloids to form thermally-induced strong gels was monitored and analyzed by means of curing tests. Throughout thermal treatments, the storage modulus showed a significant increase, especially at concentrations greater than 2.5 wt%. Mango seeds and peel-derived hydrocolloids are also able to stabilize o/w emulsions. Derived emulsions showed D50 mean diameters and zeta potential values (ζ) in the ranges from 10.04 to 82.52 μm and from -17.63 to -11.12 mV, respectively. On the basis of the observed rheological behavior of hydrogels and emulsion-forming ability, the hydrocolloids derived from mango seeds and peels possess suitable characteristics to be potentially implemented in diverse food matrices, offering functional and nutritional benefits to final consumer products.

Phenolic content of Thai Bao mango peel and its in-vitro antioxidant, anti-cholinesterase, and antidiabetic activities

Plant phenolics have been known for various biological activities. This study aims to extract and examine the presence of phenolics in Bao mango (Mangifera indica L. var.) peel ethanolic extract (MPE). Further, antioxidant, anti-diabetic (α-amylase, and α-glucosidase inhibitory activity), and anti- Alzheimer’s disease (AD) (acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and β-secretase (BACE-1) inhibitory activity) efficacy of MPE were determined. The results indicated that mangiferin (8755.89 mg/ 100 g extract) was the major phenolic compound in MPE. An antioxidant mechanism revealed that MPE had a higher radical scavenging ability (4266.70 µmol TE/g extract) compared to reducing power (FRAP) or oxygen radical absorption capacity (ORAC). Further in-vitro enzyme inhibitory assay against diabetic and AD involved enzymes showed that MPE had stronger inhibitory action against an enzyme involved in diabetes compared to their standard drug (Acarbose) (P < 0.05). While a lower IC50 value was observed against AD-involved enzymes compared to their standard drug (donepezil) (P < 0.05). The results show that Thai Bao mango peel byproduct can be a potential source of nutraceuticals to lower diabetes and improve cognitive health.

Facile synthesis of eco-friendly mango peel-derived porous carbon for optimizing microwave absorption

An environment-friendly and cost-effective method to deal with electromagnetic pollution is fabricating porous carbon from biomass as a raw material with a simple technique. The purpose of this research is to create porous carbon from mango peel biomass for optimizing microwave absorption. The resulting porous carbon (PC) has the potential to be an effective microwave absorber. Scanning Electron Microscopy (SEM) depictions also revealed the porous carbon with homogeneous shapes and uniform size distribution. Complex permittivity studies were performed to evaluate their microwave absorption capabilities, resulting in a high reflection loss of −50.2 dB at a thickness of 2.1 mm and an effective absorption bandwidth (EAB) of 3.39 GHz for the sample carbonized at 800 °C. The exceptional microwave absorption ability of porous carbon (PC) can be attributed to its effective impedance matching and consequent attenuation of microwaves through dielectric loss. This research introduces a novel biomass source, readily available in nature, which can be easily processed to enhance microwave absorption properties.

Anti‐Cancer Activity of Ethanolic Extract from ‘Bao’ Mango (Mangifera indica) Peel and Its Nanoencapsulation Against Triple‐Negative Breast Cancer Cell Lines

AbstractMango (Mangifera indica) has been one of the most cultivated fruits in Thailand and other South and Southeast Asian countries. ‘Bao’ mango is a distinct petite mango variety that is available all year round. This study aimed to investigate the antioxidant and anti‐breast cancer activities of Bao‐mango peel extract (MPE). The total phenolic content (TPC) of MPE was 280.57 ± 7.95 μg quercetin per g of powder. Based on antioxidant activity analyses, MPE had IC50values of 35.09 and 23.80 ± 0.48 μg/mL for 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) and 2,2′‐azino‐bis‐3‐ethylbenzthiazoline‐6‐sulphonic acid (ABTS) radical scavenging activities, respectively. Additionally, MPE exerted an inhibitory action against MDA‐MB‐231 breast cancer cells with an IC50of 39.08 ± 5.22 μg/mL. Furthermore, nanoencapsules loaded with MPE using chitosan‐coated poly lactic‐co‐glycolic acid (CS‐PLGA‐(MPE)) were also prepared. It exhibited spherical morphology with an average size of 251.90 ± 19.61 nm. Encapsulation efficiency (EE) of nanoparticles was 30.48 %. Moreover, the CS‐PLGA‐(MPE) exhibited higher anticancer activity by affecting cell viability and inhibiting the cell migration and invasion of MDA‐MB‐231 breast cancer cells, compared to the free MPE. Therefore, these findings indicated that MPE and CS‐PLGA‐(MPE) nanoparticles could be promising alternatives to chemicals used for breast cancer treatment.

Perseverance according to the Book of Job 2:1-13 and implications for people today

Human understanding today is always presented with the concept that those who obey and are faithful to God will be blessed and those who do evil will suffer. On the other hand, humans always want to have something obtained instantly. The book of Job struggles with that understanding and attempts to decipher the concept of recompense. Because of the reality of life in this world, humans are always faced with two sides of life, namely difficult and happy. Researchers use qualitative methods with a literature approach (librabry Research) for this paper. Job's struggles, as the book of Job testifies, are evidence of his perseverance in facing everything in life. Contrary to the concept in Israel that obedience and faithfulness bring blessings. The concept of Job in the face of hardship and pleasure is a character that every human or believer must possess. It turns out that the concept of God as the giver of blessings and punishments based on human works was renewed into a God far beyond human thought and wisdom. Man has limitations to experience God's work in this world. Man's tendency to frame God in man's limited thinking makes it difficult for man to understand what God has done. Olh is therefore in chapters 2:1-13 (are we willing to receive good from God, but not bad? Here comes Job's perseverance.)

Nyaa, ‘motlhanka wa Jehofa’! (Stop it, ‘man of God’!): An Ubuntu Pentecostal response to gender-based violence within the Neo-prophetic Movement in South Africa

Background: Statistics from the Pew Research Centre indicate that in sub-Saharan Africa, 796 million out of 822 m people claim the same Christian religious affiliation. Pentecostal Christians total 107 m. These figures suggest that religion shapes the worldview of many sub-Saharan inhabitants. Many are adherents of Ubuntu, which does not dichotomise lived experiences from the influence of the spiritual (the Supreme Being, spirits, and the ancestors). On the one hand, the World Health Organization has labelled South Africa as the rape capital of the world because it accounts for the highest figure of gender-based violence (GBV) globally. Intimate partner violence (IPV) and non-partner violence, characterised by rape and attempted rape, constitute a significant portion of sexual violence, which is the primary and highest category of GBV in South Africa. The second, third, and fourth categories are physical violence, socio-economic and financial violence, and psychological/emotional violence. Various South African courts have sentenced several pastors from the Neo-prophetic Movement (NPM) for non-partner violence.Objectives: The aim of this study is to reflect on non-partner violence within the NPM in South Africa and to respond to this scourge by applying Ubuntu Pentecostalism as a framework.Method: This article thus poses the question: How might South African Pentecostals address the scourge of non-partner violence within the NPM? It, thus, uses Ubuntu Pentecostalism.Results: The article shows that is that is possible to mobilise members of NPM and the surrounding community to counteract the scourge of non-partner violence among NPM in South Africa.Conclusion: The article concludes by providing a four-step strategy to curb th scourge of non-partner violence in the NPM in South Africa.Contribution: This strategy contributes to curbing the scourge of non-partner violence within the NPM in South Africa.

Anaerobic co-digestion of municipal mixed sludge and mango peel biowaste: Performance and stability analysis for different ratios

In an urban context, municipal mixed sludge (MMS) and fruit and vegetable waste (FVW) are becoming the major organic solid wastes in human society. Thus, anaerobic digestion as a low carbon energy strategy to minimize their environmental polluting risk was studied. To overcome the drawbacks of anaerobic digestion of MMS, an alternative approach is proposed, involving the addition of increasing proportions of mango peel pulp (MPP) as a co-substrate. Different ratios of MMS:MPP (v:v) were studied: 80:20 (T1), 70:30 (T2), 60:40 (T3). The increase in the organic loading rate was well incorporated by the reactor's biomass activity, and it had no negative effects on the reactor stability and performance operational parameters. Results indicated that the addition of MPP had a beneficial effect on specific methane production, where the highest value was registered in T2 (0.47 L CH4/g VS added), with a 1.8-fold increase in this operational parameter. Moreover, bioenergy recovery within the same trial followed the same profile, representing a two-fold increment.

Additionally, the antioxidant and antimicrobial activities associated with mango peel highlight its potential applications in food preservation and as a natural additive. The review also discusses the potential use of mango peel extracts in the development of functional foods and nutraceuticals. Furthermore, the sustainable utilization of mango peel as a value-added product aligns with the principles of circular economy and waste reduction. This comprehensive exploration of mango peel as a valuable food source underscores the need for further research and development to unlock its full potential, promoting a more sustainable and holistic approach to food utilization.

Characterization of Langra Mango Peel Powder and Assessment of Its Prebiotic and Antioxidant Potential

The possibility of developing waste by-products of food processing into functional food additives along with probiotics is an interesting avenue to research. This study investigated the nutritional and functional attributes of dried mango peel powder (MPP) of Langra cultivar and its putative potential to act as a prebiotic in the presence of two probiotic strains Lacticaseibacillus rhamnosus NCDC347 and Limosilactobacillus fermentum NCDC143 @ 2.5 &amp; 5% after 24 to 48 h fermentation. Proximate analysis revealed that the MPP contains 6.45 % moisture, 6.34 % protein, 3.88 % fat, 2.50 % ash, 32.86 % crude dietary fiber, and 47.97 % of total carbohydrate content. MP displayed substantial antioxidant potential with 54.6% DPPH inhibitory activity, 15.67 mg GAE/g TPC, 8.88 mg QuE/g TFC, OHC of 1.47 g oil/g, and a WHC of 4.7 g water/g. MPP could selectively stimulate the growth of two probiotic strains over enteric bacteria. It was revealed that a combination of MPP @5% with L. fermentum NCDC143 after 24 h fermentation had the best in vitro prebiotic activity score of 3.35 and 3.53 against Escherichia coli ATCC 25922 and Enterococcus faecalis NCDC114, respectively. The prebiotic activity score of MPP was better than commercial prebiotic malto-dextrin for all combinations of probiotic and enteric strains tested. The percentage DPPH inhibition activity of MPP increased during fermentation with L. fermentum NCDC143, highlighting its role as a source of antioxidants. These findings contribute to the formulation of synbiotic products that are able to maintain selected healthy microbiota in the human gut.

Optimization of mango peel pectin extraction (Mangifera indica L.): For the production of jam and jelly

Pectin extracted from mango (Mangifera indicia L.) peel is commonly utilized as a gel-forming agent in food and pharmaceutical applications. In Ethiopia, there is a substantial amount of mango fruit production and the peel removed from mango fruits are discarded as waste. However, there was limited scientific data on the development of pectin from mango peel and its utilization in jam and jelly making. Therefore, the study aimed to develop pectin from mango peel and utilization optimized pectin in jam & Jelly developments. For expermental work, the mango kent variety was collected from the Bako Agricultural Research Center. Seventeen experimental runs were generated after the minimum and maximum temperatures (60–100 °C), time (60–120 min) and pH (2–3) were adjusted by Design Expert® software version 13.0.5.0 using the Response Surface Methodology. All physicochemical and sensory properties were determined using standard procedures and analytical graded chemicals. The results showed that the highest (64.63 %) extraction yield of mango peel pectin was recorded at 100 °C, 60 min and pH.2. Optimum process variables for pectin yield (65.20 %) extracted from dried mango peel were recorded at temperature 94.64 °C, time 118.67 min, and pH 2.01,The optimized mango pectin yield has 497.5 equivalent weight, 6.15 methoxy, 70.3 anhydrouronic acid, and 49.69° of esterification content. Mango jam and jelly were developed using optimized pectin yield of 3.64 and 3.42, 4.30 and 4.46 for pH and titrable acidity, respectively. The results of the sensory panelists showed that mango jam and jelly developed with pectin significantly (p < 0.05) liked the aroma and general acceptability compared to the control sample. The findings highlighted that the pectin optimized from dried mango peel has a good potential to develop jams and jellies with better physicochemical properties and sensory acceptability.

Chemical analysis and bioactive compounds from agrifood by-products of peruvian crops

Many countries face the problem of agroindustrial waste elimination, which is linked to environmental damage caused by improper waste management. These wastes contain bioactive compounds often discarded due to a lack of knowledge. The objective of this study was to analyze five types of agroindustrial waste from Peru, including avocado (Persea americana) seeds, lucuma (Pouteria lucuma) seeds, grape (Vitis vinifera) pomace, mango (Mangifera indica) peel, and cocoa (Theobroma cacao) pods. This study includes proximal analysis, determination of total phenolic compound content, analysis of phenolic compounds by UHPLC– Q/Orbitrap/ESIMS/MS (Ultrahigh-performance liquid chromatography-electrospray ionization Q-Orbitrap mass spectrometry), and the evaluation of antioxidant, antimicrobial, and antifungal activities of different samples. The results showed that lucuma seeds had the highest protein content of 6.59 g/100 g DW. Mango peels showed the highest fat content of 4.89 g/100 g DW, cocoa pods had the highest crude fiber content of 26.91 g/100 g DW, and cocoa pods exhibited the highest ash content of 7.14 g/100 g DW. The highest carbohydrate content was found in avocado seeds at 85.85 g/100 g DW. Mango peels (56.66 mg GAE/g DW), avocado seeds (56.35 mg GAE/g DW), and cocoa pods (51.52 mg GAE/g DW) extracts showed the highest phenolic compound contents. Mango peel extract exhibited the highest antioxidant activities evaluated by the ABTS (995.01 μmol TEAC/g DW), DPPH (953.54 μmol TEAC/g DW), and FRAP (1661.13 μmol TEAC/g DW) assays. Extracts from cocoa pods, grape pomace, and lucuma seeds showed inhibitory activity on the growth of Staphylococcus aureus and Escherichia coli. In contrast, the extract of lucuma seeds was the only one that showed antifungal activity over Penicillium digitatum. As a result, several phenolic compounds were detected in each, indicating their potential use in developing functional foods and food preservation, among other applications.

A novel strategy to transform mango peel waste into useful product– Preparing antibacterial film containing tea polyphenols for chicken breast preservation

Studies on the use of antibacterial packaging films to delay the deterioration of meat products are gaining interest. Many petroleum-based packaging materials are difficult to degrade, seriously pollute the environment, and pose a threat to human health. This study aimed to prepare antibacterial packaging films using mango peel waste for chicken breast stored at 4 °C for 12 days. The influence of tea polyphenols on various film properties was characterized and changes in various physicochemical indicators of chicken breast meat during storage were determined. Scanning electron micrographs showed that tea polyphenols made the mango peel antibacterial film denser, and their introduction reduced water vapor transmission by 32.5%, oxygen transmission rate by 84.3%, carbon dioxide transmission rate by 80.0%. The mango antibacterial film containing 1.4 g/hg tea polyphenols effectively maintained the color and texture of chicken breast meat and inhibited water loss, pH increase, microbial growth, reproduction, and reduce the production of thiobarbituric acid by 19.0% and volatile alkali nitrogen by 60.6% in chicken breast meat, indicating that chicken breasts wrapped in this film had a longer shelf life. This study provides a basis for the further application of mango peel antibacterial films in the food industry.

Antioxidant and antimicrobial activities of mango peel and radish peel-a comparative investigation

The present study investigated the antioxidant and antimicrobial activities of Bao mango and daikon radish peel (Thai variety) ethanolic extracts. The percentage extraction yield of radish peel was higher compared to the mango peel (p &amp;lt; 0.05). However, Mango peel extract (MPE) contained higher total phenolic content (TPC) than radish peel extract (RPE) (p &amp;lt; 0.05). Similar to the TPC value, antioxidant activities including DPPH radical scavenging activity, reducing power, and peroxidation inhibition were higher in the MPE, compared to the RPE, except for metal chelating activity. The antimicrobial analyses suggested that the MPE showed lower minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values compared to the RPE (p &amp;lt; 0.05) against Gram-positive and Gram-negative bacteria. High-performance liquid chromatography (HPLC) revealed that mangiferin was the major phenolic compound present in MPE, followed by 3, 4 dihydroxybenzoic acid. Therefore, MP could be used as a promising natural antioxidant and antimicrobial agent for food applications.
