CHITIN PREPARATION AND CHARCTERIZATION FROM CHICKEN BONEZahraa A. Abdul Muhsin, Ahmed Saad Aldhamin and Shafik S. Shafik
Chitin is the second most ubiquitous natural biopolymer after cellulose on earth. Chitin is estimated to be produced almost annually as much as cellulose. Biopolymer have received recent attention in research because of their unique characteristics used in many applications and considered one of the important biopolymer. Different procedures have been adopted in extracting chitin. This work proposed a new approach using chicken bone in preparing chitin. All the bones of the chicken were used as chitin source in this work. The two chemical methods, deproteinization and demineralization were used in extracting chitin. The prepared chitin through this work was characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier transforms infrared spectroscopy (FTIR). Many experiments were accomplished through this work, experiment E5 gave the best results, which is close to the standard result. The proposed work outperformed the state of art researches through the percentage of chitin extracted. The chitin extraction was 16.25% of the total weight of all chicken bone used in the experiment, compared to the state of art researches that used chicken feat only.
