Dye contamination is a serious environmental issue, particularly affecting water bodies, driving efforts to synthesize adsorbent materials with high dye-removal capacities. In this context, eco-friendly and cost-effective derived from bioresidues are being explored recycle valorize waste. This study investigates the synthesis, characterization, application of biohydrogel made unripe plantain peel (PP), modified carboxymethyl groups crosslinked using varying concentrations citric acid (CA), an economical organic acid. The were characterized by ATR-FTIR, TGA, SEM, confirming successful synthesis hydrogels, which exhibited rough, irregular surfaces micropores. Additionally, analyzed for their pH point zero charge, swelling capacity, methylene blue (MB) dye removal efficiency. results indicate that formed 1% CA most favorable characteristics MB removal.

With the constantly escalating demand for safe food packaging, utilization of biodegradable polysaccharide-based nanocomposite films is being explored as an alternative to traditional petrochemical polymer (polyvinyl alcohol, polybutylene succinate, etc.). Polysaccharide-based have excellent mechanical properties, water vapor transmission rates, and other physical characteristics. Films can fulfill numerous demands fruit packaging in daily life. Additionally, they be loaded with various types non-toxic non-biocidal materials such bioactive substances metal nanomaterials. These enhance bacterial inhibition reduce oxidation fruits while maintaining fundamental functionality. The article discusses design preparation strategies their application preservation. films, addition materials, mechanisms action are further discussed. In addition, this research crucial preservation efforts both scientific industrial applications.

Microbial contamination challenges have led to the development of active edible coatings for fruit preservation. Herein, a Konjac glucomannan (KGM) coating loaded with Ocimum gratissimum (OG) essential oil stabilized by pectin superior resistance air permeability, oxidation, and fungal, was prepared in situ on surface Mandarin oranges enhance postharvest quality. The results demonstrated that KGM-pectin-OG (K-P-OG) 1.5 wt% exhibited good performance terms stability, adhesion, wetting. Meanwhile, had an ideal permeability due its compact dense structure based compatibility interactions between components. oxygen K-P-OG 7.9 × (10-16 g·cm)/(cm2·s·Pa), which six orders magnitude lower than KGM coating. antioxidant, vitro, vivo antifungal activities against Penicillium italicum were strengthened OG emulsion mainly depended concentration. storage showed 1.5% extended shelf life 8 days, reduced weight loss rate 13%, increased firmness POD during 24.14% 100%, respectively, compared control group. These demonstrate can effectively maintain nutrient content extend time enhancing antioxidant capacity inhibiting respiration microorganism growth. This study presents strategy developing
