Diffusive model with variable effective diffusivity considering shrinkage in thin layer drying of chitosan
Batista, Lucia de Moraes; Rosa, Cezar Augusto da; Pinto, Luiz Antonio de Almeida (Elsevier, 2007)In the thin layer drying of chitosan, a diffusive model considering the material volume change was used, due to the occurrence of shrinkage during the operation. The samples were placed in a rectangular tray with 4 mm of ... -
Optimization of deacetylation in the production of chitosan from shrimp waste: use of response surface methodology
Weska, Raquel; Moura, Jaqueline Motta de; Batista, Lucia de Moraes; Rizzi, Jaques; Pinto, Luiz Antonio de Almeida (Elsevier, 2007)The use of chitosan in diverse areas is directly related to the polymer’s molecular weight and degree of deacetylation, which depends on the conditions of chitin deacetylation. The aim of the present study consisted of ...
