- Description
- The increasing substantial generation of food waste poses a critical challenge for global waste management. A potential solution involves extracting commercially valuable products, such as biopolymers, from food waste. Cellulose biopolymer emerges as a promising candidate in this context. The current research investigates the potential of employing banana bracts (Musa acuminata) as a low-cost substrate for the extraction of cellulose biopolymer. Cellulose extraction from various residues of banana processing waste has been previously researched. However, there is a limited amount of the literature on cellulose extraction from the bracts that are left over after processing. The initial extraction phase involves an ethanol-toluene treatment to remove the laxatives, followed by an alkali treatment using KOH and bleaching using a mixture of acetic acid and sodium chlorite solution to derive white cellulose fibres. The extraction of cellulose from banana bracts yielded 36.98 0.0094% (w/w%). Examination of functional groups utilizing Fourier transform infrared provided characteristic peaks of cellulosic material. X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy were used to comprehend further the molecular architecture, thermal stability, and purity of the extracted cellulose. The cellulose mixture of varying concentrations (0.5, 0.75, and 1.0% [w/v%]) was coated on cherry tomatoes to investigate their shelf-life extension property. The cherry tomatoes (Solanum lycopersicum var. cerasiforme) coated with 0.75% (w/w%) cellulose solution retained firm structure and fresh appearance after 8days, in contrast with the decayed control group. The current investigation focuses on novel insights into the potential of banana bracts as a valuable resource in the pursuit of sustainable and cost-effective cellulose extraction, for both waste management and enhancing the preservation of perishable food items.
