Chitin and Chitosan: a review of extraction processes and applications

chitin, chitosan, biopolymers, extraction processes, chemical extraction

Sinopse

Chitin is the second most abundant carbohydrate in nature,
after cellulose, and can be extracted by chemical or biological
methods, involving steps of demineralization, deproteinization and
depigmentation. Chitin and chitosan can be obtained from chemical
or biological methods and increasingly more effective methodologies
are being developed, including green and sustainable technologies
to minimize the environmental impact in obtaining these materials.
The physicochemical properties of chitin and chitosan are being
increasingly explored, due to their properties such as biodegradability,
biocompatibility, antimicrobial activity, blood coagulation ability and
film formation ability, which allows the development of different
applications, especially in areas such as biomedicine, materials
engineering, agriculture, among others. This book offers an in-depth
exploration of the processes and methodologies for obtaining chitin
and chitosan, emphasizing both chemical and biological approaches.
It examines critical steps such as deproteinization, demineralization,
and depigmentation, while also addressing innovative green
technologies that align with sustainability goals. The text delves
into the physicochemical properties of these biopolymers, such as
their molecular weight, solubility, and viscosity, which underpin their
versatility. Furthermore, it provides comprehensive insights into their
applications, particularly in biomedicine and agriculture, showcasing
the potential of these materials to revolutionize areas like antimicrobial
solutions, food preservation, and advanced biomaterials. This detailed
treatment positions the book as a valuable resource for researchers
and practitioners in materials science and applied biotechnology
