The role of base types and concentration in the deacetylation process of manufacturing chitosan from green mussel shells (Perna viridis)

In the food industry, chitosan is useful as a preservative, edible film, heavy metal binder, and so on. Chitosan is produced by removing the acetyl groups in chitin using a strong base. Green mussel (Perna viridus) shells, which are waste from the fishing industry, have the potential to be utilized as raw materials for chitosan production because they are estimated to contain about 15-35% chitin. The deacetylation process was conducted using alkali at high temperatures, leading to the release...
