Musa spp. (banana) is consumed globally as a healthy fruit and improves the immune system. Banana blossoms are a by-product of banana harvesting rich in active substances such as polysaccharides and phenolic compounds; however, these blossoms are typically discarded as waste. In this report, a polysaccharide, MSBP11, was extracted, purified and identified from banana blossoms. MSBP11 is a neutral homogeneous polysaccharide with a molecular mass of ∼214.43 kDa and composed of arabinose and galactose at a ratio of 0.303:0.697. MSBP11 exhibited potent antioxidant and anti-glycation activities in a dose-dependent manner and can be used as a potential natural antioxidant and inhibitor of advanced glycosylation end products (AGEs). In addition, banana blossoms have been shown to decrease the levels of AGEs in chocolate brownies, which might possibly be developed as functional foods for diabetic patients. This study provides a scientific basis to further research the potential application of banana blossoms in functional foods.

Background Banana anthracnose, caused by Colletotrichum musae, is one of the most severe postharvest diseases in banana. Melatonin is widely known for its role in enhancing plant stress tolerance. However, little is known about the control of melatonin on anthracnose in postharvest banana fruit.Results In this study, exogenous melatonin treatment could significantly reduce the incidence of anthracnose in ripe yellow banana fruit and delay fruit senescence. However, melatonin treatment did not affect the growth of Colletotrichum musae in vitro. Transcriptomic analysis of banana peel showed that 339 genes were up-regulated and 241 were down-regulated in the peel after melatonin treatment, compared with the control. Based on GO terms and KEGG pathway, these up-regulated genes were mainly categorized into signal transduction, cell wall formation, secondary metabolism, volatile compounds synthesis and response to stress, which might be related to the anti-anthracnose of banana fruit induced by melatonin treatment. This view was also supported by the increase of volatile compounds, cell wall components and IAA content in the melatonin-treated fruit peel via the metabolomic analysis. After melatonin treatment, auxin, ethylene and mitogen-activated protein kinase (MAPK) signaling pathways were enhanced, which might be involved in the enhanced fruit resistance by regulating physiological characteristics, disease-resistant proteins and metabolites.Conclusion sOur results provide a better understanding of the molecular processes in melatonin treatment delaying banana fruit senescence and anthracnose incidence.

A low-cost biochar was prepared through slow pyrolysis of banana pseudostem biowaste at different temperatures, and characterized by surface area and porosity analysis, scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS). It was shown that the biochar prepared at low pyrolysis temperature was rich in oxygen-containing groups on the surface. Adsorption experiments revealed that the biochar prepared at 300 °C (BB300) was the best adsorbent for Cr(VI) with 125.44 mg/g maximum adsorption capacity at pH 2 and 25 °C. All the adsorption processes were well described by pseudo-second-order and Langmuir models, indicating a monolayer chemiadsorption. Furthermore, it was demonstrated that adsorption of Cr(VI) was mainly attributed to reduction of Cr(VI) to Cr(III) followed by ion exchange and complexation with the biochar.Keywords:biochar;banana pseudostem;chromium;adsorption mechanism

An investigation of the metabolism and transfer of imidacloprid (IMI) in banana plants and soil was performed using high-resolution mass spectrometry. Results indicated the presence of eight IMI metabolites in soil and leaves that resulted from hydroxylation of the imidazolidine ring, the reduction and loss of nitro groups, and oxidative cleavage of methylene bridges. Six metabolites, including 4/5-hydroxy IMI (4/5-hydroxy), IMI olefin (olefin), and 6-chloronicotinic acid (6-CNA), were detected in the fruits following leaf treatment, while only three were detected after soil treatment. Quantitative analysis showed that the total amount of imidacloprid and its metabolites transferred from leaves to fruits was higher than that transferred from soil to fruits. Therefore, leaf transfer was considered the main means by which IMI and its metabolites transferred to banana fruits. We found that adjuvants tank-mixed with IMI could reduce the total concentration of pesticide transfer from leaves to fruits, especially reducing the amount of metabolites transformed from the reduction and loss of nitro groups and oxidative cleavage of methylene bridges, thus reducing the pesticide residue in fruits and achieving the purpose of reducing the safety risk.

The dye and heavy metal are two principal concomitant pollutants in industrial wastewaters, posing a serious threat to public health and the environment. Herein, we developed a novel strategy to convert banana peels into hierarchically porous carbon (BPCA) and porous carbon oxide (BPCAO) for the simultaneous removal of methylene blue (MB) and Co(II). The as-prepared carbons were systematically characterized by SEM, TEM, BET, FT-IR and XPS. Compared to BPCA, BPCAO showed a better adsorption performance due to its abundant surface oxygen-containing groups. In the mono-component systems, both MB and Co(II) adsorption onto BPCAO were well described by the pseudo-second-order and Langmuir models. The maximum adsorption capacities of MB and Co(II) were calculated to be 1303.54 and 122.39 mg/g at 298 K, respectively. In the binary system, the interaction between MB and Co(II) was determined and it depended on the initial concentration of Co(II). The adsorption mechanism of MB involved electrostatic interaction, π-π stacking and hydrogen-bonding while that of Co(II) was mainly ruled by the complexation and/or ion-exchange. This study indicated BPCAO could be a favorable biomass-derived adsorbent for the simultaneous removal of the dye and heavy metal.

Banana is one of the most important food crops which is generally planted in tropical countries and has beneficial applications in the food industry. A large amount of by-products such as leaves, inflorescence, pseudostem, and rhizomes serves as a source for different industries. Most of these by-products may serve as an undervalued commodity with a limited commercial value, application and in some cases, it is considered as an agricultural waste. This also paves the way to utilize a huge amount of untapped biomass and resolve some of the environmental issues. Most of the edible bananas are cultivated mainly for their fruits, thus, banana farms could generate several tons of underused by-products and wastes. The present review mainly discusses the utilization of banana by-products such as peels, leaves, pseudostem, pseudostem juice, stalk, and inflorescence in various industries as a thickening agent, alternative source for renewable energy, nutraceuticals, livestock feed, natural fibers, coloring agents, bioactive compounds, and bio-fertilizers. Banana waste serves as a potential source for the production of valuable products and preserves renewable resources and provides additional income to the farming industries.

The study aimed to develop a nanofiber film for photocatalytic degradation of ethylene and slowing down the ripening of banana fruit. Nanofibers containing different amounts of TiO2 nanoparticles (1 wt%, 5 wt%, and 10 wt%) were prepared using electrospinning method. Nanofibers containing 5 wt% TiO2 exhibited a nano-scale structure, good nanoparticle uniformity, and an anatase phase as characterized by scanning electron microscopy, energy dispersive X-ray spectrometer, transmission electron microscopy, and X-ray diffraction. Nanofibers containing 5 wt% TiO2 were tested in a photocatalytic reactor and showed higher photocatalytic activity for the degradation of ethylene. The utility of the photocatalytic reaction was further confirmed via a banana fruit-ripening test. The TiO2 nanofiber successfully delayed the color change and softening of bananas during storage. The results suggest that the TiO2 nanofiber offers photocatalytic degradation of ethylene and could potentially be used as packaging material for delaying postharvest fruit ripening.

Banana is one of the most important fruits over the world. The chemical composition is critical for the organoleptic properties and health benefits. As one of the leading bioactive components in banana pulp, the polysaccharides may contribute to the beneficial health effects. However, their precise structure information remains unknown. A leading acidic polysaccharide (ABPP) of banana pulp was purified and identified by nuclear magnetic resonnance spectroscopy (NMR) and gas chromatography-mass spectrometry (GC–MS). →4-α- d -Gal p A-1→ and →4-α- d -Gal p AMe-1→ constituted the backbone. No branch chains were detected. The molecular weight was determined to be 8.9 kDa by gel permeation chromatography, which was smaller than previously reported fruit-derived polygalacturonic acids. The precise structure was identified as below. Digestion by enzyme would lead to production of oligogalacturonic acids and quick accumulation of 5000–7000 Da fraction.

Background Behavior-based manipulation is an essential part of Drosophila integrated pest management (IPM). Effective compounds are useful for improving the efficiency of baits and the development of attract-and-kill or push–pull strategies to manage Drosophila populations. Here, we investigated the olfactory behavior of two Drosophila species, as well as their pupal parasitoid, to volatiles from bananas, for the identification of effective compounds to control fly populations. Results The results showed that overripe bananas were most attractive to both flies, with a higher attraction index (AI) in Drosophila melanogaster than in Drosophila suzukii . The profiles of volatile organic compounds (VOCs) from bananas with three different ripening stages were compared, and six VOCs were selected for behavioral tests. D. suzukii showed significantly different responses to isoamyl alcohol with D. melanogaster . The effects of ethyl butyrate and ethyl isovalerate on the two flies were dose-dependent, with lower concentrations acting as repellent and higher concentrations acting as attractant. Isoamyl acetate, isoamyl butyrate and isoamyl isovalerate (0.005–0.05% v/v) were attractive to both flies. The parasitoid wasp Pachycrepoidus vindemmiae was repelled by isoamyl alcohol and ethyl butyrate, and attracted by ethyl isovalerate, but showed no significant response to isoamyl acetate, isoamyl butyrate and isoamyl isovalerate at the tested concentration . Conclusion This study indicated that the behavioral response of Drosophila to the odor of chemical compounds is dose-dependent. Isoamyl alcohol and isoamyl acetate at certain concentrations could be used as repellents, whereas ethyl isovalerate as an attractant in control strategy design for D. suzukii. © 2023 Society of Chemical Industry.

Banana puree, which serves as a vital intermediate raw material in the production of banana-based products, is prone to browning and aroma loss during the processing stage. This study focuses on elucidating the patterns of browning and aroma loss and investigating the mechanisms behind these phenomena, using Cavendish banana and Pisang Awak banana as subjects. The results showed that Cavendish banana exhibited superior processing suitability in terms of flavor. Through untargeted metabolomics analysis, it was found that the homogenization process affects aroma synthesis and browning pathways, particularly α-linolenic acid metabolism. Targeted metabolomics analysis further identified that the synergistic effect of multiple phenolic substances plays a crucial role in banana browning. Additionally, research indicated that adding 0.5 % cinnamic acid could effectively delay the browning of banana puree and enhance overall flavor quality by inhibiting lipoxygenase activity. This study offers a theoretical foundation for addressing bottleneck issues in the banana processing industry.

Ethylene-induced quality deterioration of postharvest fruits aggravates food wastage worldwide, therefore, the development of effective approaches for reducing ethylene concentration of packaged fruits is of paramount importance in extending shelf life and minimizing food spoilage . In this work, a modified HKUST-1 (i.e., HKUST-1-P) was added to a chitosan quaternary ammonium salt (CQAS)-gelatin matrix to prepare a food packaging film (i.e., HPCGF) with ethylene adsorption property and improved water stability. Molecular simulation revealed that the ethylene preferentially bonds to the C and O sites of HKUST-1, followed by the H and Cu sites to achieve adsorption. The physical adsorption performance of HKUST-1 and HKUST-1-P was 89.91 and 89.05 cm 3 /g STP, respectively. Moreover, HPCGF showed improved physicochemical (e.g., thermal stability, mechanical, and gas barriers) properties that are beneficial for food packaging. As a validation experiment, the effectiveness of HPCGF for preserving a climacteric fruit (banana) was demonstrated by absorpting the ethylene, maintaining the color and hardness, delaying lipid peroxidation , and prolonging shelf life of bananas. This study will aid in the development of novel packaging materials with ethylene adsorption properties for preserving perishable foods, helping reduce food waste.

Ethylene, released from fruits and vegetables (F&V) after harvest and during storage, often accelerates the ripening or over-ripening and may be caused decay, leading to substantial economic loss. Dendritic mesoporous silica supported (DMS) platinum (Pt/DMS) catalyst as ethylene scavenger was prepared and various characterization results indicated that the as-prepared Pt/DMS with ultra-low Pt loading exhibited excellent ethylene scavenging performance, which could maintain the complete ethylene conversion (100%) over 50 h at 25 °C and even 0 °C for 100 min with superior consecutive cycles by repeating the use of Pt/DMS. The presence of Pt/DMS delayed banana softening, and browning, reduced weight loss and kept the freshness for 14 days. In conclusion, the active packaging incorporated with Pt/DMS catalysts with high ethylene scavenging efficiency is expected to be extremely beneficial to the post-harvest storage life of other fruits and vegetables that needs further related investigation.
