The objective of this study was to produce high viscosity chitosan from shrimp chitin prepared by using a two-step biological treatment process: decalcification and deproteinization.
Glucose was fermented with Lactobacillus pentosus L7 to lactic acid.
At a pH of 3.9 ± 0.1 , the calcium carbonate of the shells was solubilized in 48 hours.
The amounts of residual calcium in the form of ash ( 1.4 ± 0.5 % ) and crude protein ( 23.2 ± 2.5 % ) were further eliminated by the activity of proteolytic Bacillus thuringiensis SA.
After decalcification and deproteinization of the shrimp shells, residual calcium and crude protein of shrimp chitin flakes were 1.7 ± 0.4 % and 3.8 ± 1.3 % , respectively.
Chitin was deacetylated with 50% NaOH at 121°C for 5 hours.
After deacetylation, the chitosan had residual calcium, crude protein content, and degree of acetylation of 1.6 ± 0.6 % , 0.4 ± 0.3 % , and 83.2 ± 1.5 % , respectively.
The viscosity of chitosan prepared from chitin extracted by this two-step biological process was 1,007 ± 14.7 m P a · s , whereas chitosan prepared from chemically processed chitin had a viscosity of 323 ± 15.6 m P a · s , indicating that biologically purified chitin gave chitosan with a high quality.
