ABSTRACT

In this experiment, ants were used to extract lipids and proteins, and then decolorized. Finally, the alkali immersion method was used to remove acetyl groups and extract chitosan. The effect of alkali immersion method on the deacetylation of chitosan was determined by different temperature, treatment time and material-liquid ratio, so as to obtain the best conditions of deacetylation of chitosan. The experimental results show that the optimal condition for deacetylation of chitosan is 85℃, time 4 h, material-liquid ratio of 1:25. Chitosan has physiological functions such as bacteriostasis, fat reduction, anticancer, and improving immunity. It contains excellent cell affinity, degradability and biocompatibility, as well as various health functions such as enhancing immunity, improving digestive function, reducing cholesterol, regulating human acid-base metabolism balance, and eliminating harmful heavy metals.
