Abstract:The current investigation deals with the application of a one-pot system to facilitate the production of cellulose nanocrystals (CNCs) from banana peel by a combination of microwave pre-treatment and mild oxidative hydrolysis with hydrogen peroxide (H2O2, 0–30 wt%) and sulfuric acid (H2SO4, 0–10%). H2O2 causes decolorization of the banana peel suspension from dark brown to light yellow, while further treatment with H2SO4 produces a white suspension, indicating successful removal of the non-cellulosic component… Show more
“…CNF and LCNF are commonly extracted from plants such as trees, and agricultural wastes as the promising raw materials such as pampas grass, silk thread, coconut, Phormium tenax [13], Muntingia calabura [14], lemongrass [15], lettuce peel [16], sugarcane bagasse [17], corn straw [18], Eucalyptus [19], pineapple crown [20], algae Gracilaria sp. [21], banana peel [22,23], and banana pseudo-stem [24].…”
This study presents a novel approach for the extraction of cellulose nanofibers (CNF) and lignocellulose nanofibers (LCNF) from Musa basjoo pseudo-stems, a relative of bananas, without the need for extensive drying. Instead, wet pseudo-stems were compressed and treated with NaOH solutions at varying temperatures and durations. The extracted material exhibited the characteristic peaks of cellulose I in X-ray diffraction (XRD) patterns, similar to those obtained from dried pseudo-stems. Fourier-transform infrared (FT-IR) spectroscopy confirmed the presence of cellulose I in the treated material and lignocellulose nanofiber clearly shown at 1600-1500, 1421, 1365, and 1161 cm-1. Composition analysis by Van Soest fiber analysis revealed a higher cellulose content in the treated material of wet pseudo-stems compared to that obtained from dried pseudo-stems, indicating the effectiveness of this low-energy extraction method. Meanwhile, field-emission scanning electron microscopy (FE-SEM) images demonstrated clear LCNF in the nanometer scale fibers after NaOH treatment. Overall, this study successfully demonstrated the extraction of LCNF from wet pseudo-stems of Musa basjoo with NaOH treatment at 70°C for 3 hours with 80% extraction result, providing a more efficient and low-energy approach for utilizing waste from Musa basjoo and bananas.
