Chitosan is a polysaccharide obtained from chitin and agricultural, therapeutic, and industrial processes. Among these, the food industry seems to be the one that exploits this raw material preparation, or even as beverage additives biotechnological applications of chitosan in the food industry. For that, searches in scientific bases were used to carry out the bibliographic survey (ScienceD Springer, TandFonline, PubMed, Wiley Online Library and Google Scholar). A large volume of publications was identified, signaling the importance of the topic for the industrial area, from the available publications properties (biodegradability, biocompatibility, atoxicity) and that occasional deficiencies can be addressed by associating this polymer to other natural compounds. The scientific volume
