Abstract:

 A cuttlebone sourced from Sepia officinalis, acquired from the Iskenderun fish market, served as the raw material for the extraction of chitin CT and chitosan CS. The chemical structure and physico-chemical properties of both CT and CS were comprehensively characterized through Fourier-transform infrared FTIR, X-ray diffractometry XRD, and scanning electron microscopy SEM. The yields of CT and CS obtained from the cuttlebone of S. officinalis were calculated as 32.1 and 72.6, respectively. The results of FTIR spectrum analysis revealed the presence of functional groups at various bands, confirming the samples to be CT and CS. The deacetylation degree DD value was determined to be 84.20 based on the FTIR results. The crystal index CrI of CT obtained from the cuttlebone was calculated as 60.13. Morphological distinctions between CT and CS biopolymers were emphasized by the results of SEM analysis. The successful extraction of these biopolymers from the cuttlebone of S. officinalis, species of significant commercial importance and widespread consumption, was accomplished. These biopolymers derived from the shells of marine animals can be utilized as sustainable and environmentally friendly materials in various applications. These have the potential to offer alternative and innovative solutions in various fields such as batteries, microwave electronics, packaging materials and the pharmaceutical industry.

 İskenderun balık pazarından temin edilen Sepia officinalis kaynaklı mürekkep balığı kemiği, kitin CT ve kitosan CS üretiminde kullanıldı. Hem CT hem de CSnin kimyasal yapısı ve fiziko-kimyasal özellikleri, Fourier-dönüşümlü kızılötesi FTIR, X-ışını difraktometre XRD ve Taramalı Elektron Mikroskobu SEM aracılığıyla kapsamlı bir şekilde karakterize edildi. Mürekkep balığı kemiğinden elde edilen CT ve CS verimleri sırasıyla 32,1 ve 72,6 olarak hesaplandı. FTIR spektrum analizi sonuçları, çeşitli bantlarda işlevsel grupların varlığını ortaya koyarak örneklerin CT ve CS olduğunu doğruladı. Deasetilasyon derecesi DD değeri, FTIR sonuçlarına göre 84,20 olarak belirlendi. Mürekkep balığı kemiğinden elde edilen CTnin kristal indeks CrI değeri 60,13 olarak hesaplandı. SEM analizi sonuçları, CT ve CS biyopolimerleri arasındaki morfolojik farklılıkları vurguladı. Bu önemli ticari öneme sahip ve yaygın tüketilen bir tür olan S. officinalisin kemiğinden başarıyla elde edilen bu biyopolimerler, denizel canlıların kabuklarından elde edilen sürdürülebilir ve çevre dostu malzemeler olarak kullanılabilir. Bu malzemeler, piller, mikrodalga elektronikler, ambalaj malzemeleri ve ilaç endüstrisi gibi çeşitli alanlarda alternatif ve yenilikçi çözümler sunma potansiyeline sahiptir.
