Abstract

Banana, botanically called Musa spp. is among the most cultivated and consumed fruits, which generates a huge amount of waste (peel) annually.The current review was to combine the activities and beneficial aspects of banana peel.The organic composition of banana peel comprising lipids, fibers, carbohydrates and protein which results in presence of several bioactive molecules.The literature revealed that these bioactive compounds including alkaloids, flavonoids, phenolics, steroids (tannic acid, catechol, β-sitosterol, ferulic acid) help to perform different biological activities and cures antitumor, antiparasitic, antibacterial, antifungal, antiaging, antioxidant and antiviral activities.The mechanism of its bioactive compounds helps to cure infections and diseases.The study states that banana peel is a valuable byproduct which has several benefits and it can be used in different industries like pharmaceutical, cosmetics, food, lather, biodiesel and bioethanol.

TL;DR

This narrative review argues that banana peel is an underused source of nutrients, bioactive phytochemicals, and functional/medicinal agents, with possible applications in food, pharmaceuticals, cosmetics, and bioenergy. It compiles compositional and bioactivity data from prior literature but does not present new experiments or a systematic synthesis.

Key findings

  • Banana peel is reported to contain carbohydrates, protein, fat, ash, fiber, minerals, amino acids, and bioactive classes such as alkaloids, flavonoids, phenolics, tannins, carotenoids, sterols, active amines, and polyamines. Proximate values include peel moisture 75.3±3.26, protein 5.3±0.02, crude fat 5.93±0.13, ash 15.29±0.05, and carbohydrates 8.8±0.54; pulp values differ. Amino acid values include leucine 10.97 g/100 g, phenylalanine 9.56 g/100 g, isoleucine 9.50 g/100 g, and lysine 7.16 g/100 g, with most listed amino acids exceeding the cited FAO/WHO standard except lysine.
  • Antioxidant-related findings include carotenoid content of 64 µg/g, gallocatechin at 158 mg/100 g DW in peel versus 29.6 mg/100 g DW in pulp, total phenolic content ranging from 4.95–47 mg GAE/g DM, and green peel phenolic content reported as 15–45% higher than ripe peel and 52% higher than over-ripened peel. Antioxidant assay results vary widely by solvent and method.
  • Antimicrobial activity is reported against Gram-negative and Gram-positive bacteria and fungi, with inhibition zones varying by solvent and organism; examples include Pseudomonas aeruginosa 9–19.57 mm, Escherichia coli 9–18.15 mm, Staphylococcus aureus 10–19.57 mm, and Candida albicans 9–17.61 mm.
  • Medicinal and cosmetic claims include anti-hyperglycemic, anti-ulcer, anti-inflammatory, and skin-related effects. Reported values include nitric oxide inhibitory activity with IC50 = 6.68±0.34 µg, an SPF value of 10.67 for ethanol extract with bisulphite immersion, and ulcer inhibition of 83.33% against ethanol-induced ulcers versus 100% against aspirin-induced and cold-restraint stress-induced ulcers.

Methods

  • Narrative review design: the paper synthesizes published literature on Musa spp. peel composition, bioactive compounds, and biological activities rather than reporting primary experiments.
  • Data are presented through tables on proximate composition, amino acids, minerals, bioactive compounds, antioxidant assays, and antibacterial activity.
  • No systematic search strategy, inclusion criteria, quality appraisal, or meta-analysis is described.

Limitations

  • The paper states no limitations.
  • Evident limitations: it is a narrative review without systematic search or critical quality assessment, many claims rely on secondary citations, and the tables contain inconsistent units, missing values, and heterogeneous conditions such as different solvents, varieties, and ripening stages.
  • Evident limitation: no new experimental validation is provided, so the medicinal and industrial potentials are largely inferential and require further testing.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Amino-acid comparison reverses several table values

    Minor

    The text says the listed amino acids exceed the standard except for lysine. Table 2 shows threonine and valine below their comparison values, while lysine is above its comparison value.

  • Gallocatechin study is attributed to the wrong numbered reference

    Minor

    The text attributes the gallocatechin comparison to Shinichi et al. [83], but reference 83 lists Agbo and colleagues, not Shinichi and colleagues.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
