“…Banana is a prominent tropical fruit with a high nutritional value [1,2]. It is freshly consumed or processed into different products, such as a snack, pesticide, or food colorant [3][4][5][6]. The popularity of bananas as functional foods has significantly increased due to their high carbohydrate content and low digestibility [7].…”

Methods and Potential in Valorization of Banana Peels Waste by Various Extraction Processes: In Review

Over 114 million metric tons of bananas are produced each year. The peel, which accounts for roughly one-third of the fruit’s weight, is commonly discarded as waste in the food industry. For centuries, the peel has been prized for its potential to heal a host of ailments. This by-product contains a large concentration of compounds with potent antioxidants linked to several health benefits. Consequently, the extracted valuable components, such as pectin, from this by-product could be applied to the pharmaceutical and food industries. More than 13% of pectin recovery is extracted by current extraction methods, such as ultrasound-assisted extraction. Subcritical water extraction also successfully extracts the pectin with high quality of extract. This review focuses on banana production and the role of pectin. Significant factors affecting its presence within the banana peel, the extraction methods, and current extraction applications are also presented and discussed, highlighting future research into its potential uses.

“…Banana contains antioxidants with many health benefits. However, the use of chemicals such as Thiabendazole (TBZ), Mancozeb and Benomyl to reserve the fruit is detrimental to the health of consumers and harmful to the environment [16,17]. Therefore, research efforts and innovative methods are under exploitation towards finding sustainable solutions as alternatives to replace the current chemicals being used to preserve banana.…”

An investigation was carried to assess in-vitro management of crown rot disease on Banana using extracts of cocoa leaves. The causative organism (Botryodiplodia theobromae) was sub cultured and the concentration determined through microbial count. Different cocoa leaves extracts were prepared using two different solvents. A conventional fungicide known as Mancozeb was used as a positive control and the nutrient broth only served as negative controls to help in assessment of the antimicrobial effect of the cocoa leave extracts. Phenolic Methanol Extracts (PME), Crude Cocoa Leaves Aqueous Extracts (CCAE) and Mancozeb were employed to prepare aqueous solutions through serial dilution with varied concentration. The nutrient broth (100 µL of double strength), 100 µL each of the plant extract concentrations, and 20 µL of inoculums were dispensed in a sterile micro-titre plate containing 96 wells. Incubation of the micro-titre plate was carried out at a temperature of 37°C for 1 day (24 hours). Susceptibility or otherwise of the microorganism (B. theobromae) from four sample stations was analyzed with 20 µL of a 5% solution of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT. The presence of blue-black wells indicated the growth of B. theobromae. The experiment was conducted in triplicates for PME (refined), CCAE and Mancozeb. The minimum inhibition concentrations (MICs) of PME (refined) that inhibited the growth of B. theobromae collected from four different locations were 5mg/ml, 2.5 mg/ml, 10 mg/ml and 2.5 mg/ml respectively for B. theobromae (B1)(Offinso), B. theobromae (B2)(Effiduase), B. theobromae (B4)(Kejetia) and B. theobromae (B5)(Ejisu) which was lower compared to the MICs of CCAE which was 30 mg/ml for the four sample stations. Comparatively, the MIC of the PME (5 mg/ml, 2.5 m g/ml, 10 mg/ml and 2.5mg/ml) was almost equivalent to the MIC of the conventional fungicide (Mancozeb) (2.5 mg/ml) for all the four sample stations of B. theobromae.

“…Moreover, CO2 can be recycled safely, which represents an economic and environmental benefit (Crampom et al, 2011). Because of these characteristics, this technique has been investigated exploring different kind of raw materials with the objective to obtain high aggregated value components (Sartori et al, 2017).…”

Supercritical extraction process has been used to obtain bioactive compounds from microalgae biomass that differs in composition because it has protein, esters, carotenoids, chlorophyll, enzymes, antibiotics, vitamins, and hydrocarbons. Due to this, the study of the technical feasibility of supercritical extraction of microalgae and the evaluation of the chemical composition from residual biomass of microalgae Desmodesmus sp. is the goal of this work looking for its reutilization in cosmetic, food and pharmaceutical applications. The experimental unit used is formed, basically, of a 42 mL extractor, a high pressure pump, and a micro-metering valve used for sampling. The study showed that it was obtained a higher mass yield at 90 °C and 440 bar of pressure. The residual biomass still contained a high percentage of proteins and carbohydrates, indicating that it could be used in nutraceuticals applications, and as biofertilizers.
