The purity of the chitin powder obtained through this process was compared with that of the chitin powder extracted through traditional methods. The results indicated that the highest purity of chitin (79.65%) was achieved when using DESs with ultrasound assistance. It is higher than the purity of chitin (75.63%) extracted under the same processing conditions but without the ultrasonic assistance. The purity of the obtained chitin was lower than that of the traditionally extracted chitin, but it had a higher recovery efficiency. In this study, envừonmentally friendly DES was used in order to demonstrate the potential of DES in recovering natural biopolymers.
