Pembuatan Dan Karakterisasi Kitosan Kulit Udang Galah

Abstract: Kitosan merupakan biopolimer yang diturunkan dari kitin, sumber alam yang dapat diperbarui yang sangat berlimpah di dunia setelah selulosa. Kitosan disintesis dari sumber alam yang berasal dari limbah krustasea, ikan, dan kulit udang. Salah satu aplikasi limbah kulit udang yang paling umum yaitu isolasi kitosan. Preparasi kitosan terbagi menjadi tiga tahap. Deproteinasi, dealuminasi, dan deasetilasi. Isolasi kitosan meliputi preparasi limbah kulit udang menjadi kitin dan deasetilasi kitin menjadi kitos… Show more

“…This degree of deacetylation in this study is better compared to the degree of deacetylation of chitosan from fishery waste, which was 61% (Ahmed, 2015) and from other L. vannamei shells, which was 76.24% (Imtihani & Permatasari, 2020). Azizati (2019) stated that the degree of deacetylation of chitosan from freshwater prawn shells is 93.47%. According to Aulia & Rahayu (2015), the higher the degree of deacetylation of chitosan, the lower the acetyl groups, leading to stronger interactions between ions and hydrogen bonds.…”

“…This process employed NaOH to catalyze the hydrolysis of chitin, transforming it into chitosan. Within the deacetylation process, the linkage between carbon within acetyl groups and nitrogen is disrupted, resulting in the formation of amine groups (Azizati, 2019). The intricate mechanism of this reaction is illustrated in Figure 1b.…”

“…Zam et al (2021) melaporkan adanya pita serapan pada daerah 3.448,72 cm -1 yang juga merupakan pita serapan OH‾, namun terdapat pita serapan lemah antara 3.748,82-3.873,06 cm -1 pada kitosan yang diyakini sebagai pita serapan N-H yang berasal dari gugus amida. Pada spektra FTIR kitosan, terdapat puncak serapan pada daerah 3.448 cm -1 (vibrasi ulur N-H dan OH‾ dari kitosan) 2.877 dan 1.381 cm -1 (vibrasi ulur C-H), 1.658 dan 1.324 cm -1 (amida I dan amida III), 1.597 cm -1 (vibrasi tekuk NH 2 yang kemungkinan overlap dengan amida II) (Azizati, 2019).…”
