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.eninfo:eu-repo/semantics/openAccessUltrasonicationAegle marmelos shellPolysaccharidePhotocatalytic dye reductionEdible coatingArticle10.1016/j.fochx.2024.10189524Q1WOS:0013428829000012-s2.0-8520664725239498254N/A
