Physicochemical and antibacterial properties of chitosan extracted from swimming crab shells and wooden grasshoppers using different extraction methods

Marine by-products and insects are among the sources of chitin used in chitosan production and increase the value of the product that may be used in the food industry. The conversion of chitin to chitosan requires proper extraction methods in order to minimise energy use and waste while also producing good-quality chitosan. This study aimed to evaluate different methods of extracting chitosan from two sources and to characterise its physicochemical and antibacterial properties. The study...
