In both methods, 500 g of shrimp waste, 7% (w/v) inoculum, and 10 % (w/w) sucrose were used, incubating at 30 °C. The purification procedure involved treatment with 0.4 M NaOH and 0.6 M HCl.

SEM-EDS analysis was conducted to examine morphology, elemental composition, and mineral distribution. Crystalline phases were quantified by X-ray diffraction, including amorphous content, crystallinity index, and α-chitin crystal domain size. The crystalline phases detected included α-chitin, hydroxyapatite [Ca₅(PO₄)₃OH], calcite [CaCO₃], and portlandite [Ca(OH)₂]. FT-IR spectroscopy confirmed the presence of α-chitin, phosphate, and carbonate groups. TG-DSC analysis revealed that irradiated samples exhibited slightly lower thermal stability than non-irradiated ones.
