Abstract: (3364 Views)
Different factors are involved in the removal of inorganic compounds from the shells of crustaceans. In this study, different effective factors were optimized for the removal of inorganic compounds from the chitin of crab shell Portunus segnis. The best yields were obtained with hydrochloric acid (99.05 ± 0.94). Some organic acid (acid acetic, acid lactic and mixture of them) showed a good potential for inorganic acid substitution for removal of inorganic compounds. In general, an increase in the concentration of acid (up to 10%), ratio powder to acid (w/v)(up to 1:20), temperature (up to 50°C) and time (up to 1h) were associated with the increased the efficiency of this process but excessive amounts of these factors increase the costs and cause negative effects on the chitin structure. Microwave and shakers save time in order to achieve the best efficiency. Moreover, reducing the sample size of powder was correlated with the efficiency increase of the removal of inorganic compounds. The optimization of the extraction method can increase the quality of substance and save the energy, time and cost.
