Özet
Aegle marmelos (AM) fruit shell, considered waste, is an excellent source of bioactive compounds, including polysaccharides. Therefore, this study focuses on the extraction of AM polysaccharides using an ultrasonicationassisted approach. Different parameters, including ultrasonic power (200-600 W), time (5-15 min), and solid-tosolvent ratio (10-20 mg/mL), were employed, and significantly (p < 0.05) higher yield (16.93 %) was achieved at 400 W for 10 min. Monosaccharides composition revealed galactose (30.56 +/- 0.76 %), galacturonic acid (24.72 +/- 0.12 %), arabinose (17.26 +/- 0.35 %), xylose (11.48 +/- 0.21 %), glucose (10.52 +/- 0.26 %), and rhamnose (5.39 +/- 0.67 %), which were then confirmed by C-13 spectrum. AM polysaccharides revealed nanoscale size with excellent structural crystallinity and thermal stability. Edible coatings of varying concentrations (0.5-2 %) were formulated and optimized 1 % coating, demonstrating efficacy in mitigating weight loss, microbial proliferation, and browning in cut apples. As well, AM polysaccharides prominently degraded 82.79 +/- 0.39 % of methyl green. Overall, bael shells as a valuable source of polysaccharides, offering the potential for both photocatalytic dye degradation and food preservation.
